The use of lightweight blocks in construction helps to reduce dead loads and reinforcing steel by up to 18% compared with traditional concrete blocks, as the weight of the pozzolanic blocks is decreased to 45% less than that of traditional concrete block.
The pozzolanic block is designed for high buildings so it is perfectly suitable for high buildings, which reduces dead loads and maintains durability and stability. The pozzolanic blocks are used in all modern and traditional construction. It is an alternative for traditional cement blocks, hospitals, hotels, restaurants, Conferences, mosques, churches, apartments, palaces, villas, conditioning rooms, and other high and standard buildings.

The nature of the gaps within the volcanic blocks and the neutral nature of the pozzolana material shall reduce the passage of inside out the building in addition to the acoustic echo frequencies of big halls and have a high capacity to absorb the sound, where sound insulation reaches 2.5 cm / decibel.
Pozzolana ability to absorb sound and curb the vibration of mechanical energy comes from the nature of the vacuum pozzolana material, which constitutes more than 60% of its size, so it is reducing the noise inside out the building, echo frequencies in big halls and prevent the passage of vibration and sounds of machines. It also has a high capacity to absorb overall noise which includes all the annoying and unwanted sounds resulting from the external environment and Transient Noise which is ongoing and continuous, interrupted after a period of time and shortly replaced by other sounds (trains, planes, cars) in addition to Pulse Noise which includes all the annoying and unwanted sounds that follow at short periods and are more striking on the human because of its very loud.
The efficiency of walls in preventing noise passage depends on its mass, whenever it is thicker; it is better in preventing the passage of noise.
The use of blocks and pozzolanic plaster makes the building an independent case isolated from outside and makes the apartments independent to hear sounds and noise and creaking water coming from the top.

1-Hollow Blocks

The reason why it can bear high temperature, it contains a high percentage of silica, and non-combustible and non-Fusible alumina, In addition to its volcanic origin, which makes it resistant to high temperatures of not more than 400 degrees. It is suitable for buildings that require fire resistance. 

2-Solid Blocks

The production of fire-resistant blocks manufactured of pozzolana material and what it contains form solid elements such as aluminum silicate, titanium, quicklime and slaked lime and fire-resistant cement as a main bond material between the granules of materials, makes it capable of bearing high temperatures up to 900 ° C and suitable for the use in metal melting furnaces, fireplaces, boilers rooms and fire-resistant buildings. 

The following table shows Fire resistance for different types of blocks ( Fire Resistance Table )

Under central pressure of up to 250,000 kg per square meter, using an automatic production line, vibration strength of 5000 rpm, and the nature of volcanic Zeolitic tuff material, which contains a high percentage of silicate used in the manufacture of light-processes blocks, so the pressure resistance shall reach up to 6 Kg / cm, which provides a lot of values of reinforced steel, in addition that the lightweight property helps in the technical Geometric design of buildings that cannot be borne by ordinary concrete 'in addition to not cracking or breaking during the installation of pins or the installation of door hinges and the strength of high adhesion by plastering and building stones.
The use of lightweight pozzulanic blocks makes the built buildings a block of strength and durability capable of handling all weather, vibration and absorbs mechanical shocks.

Human in nature depends on the disposal of excess dampness in the form of gas or liquid, if found inside his home.
We feel tightness and disturbed when the relative humidity in our home is more than 70% and we also disturbed by the appearance of mold on internal walls.
The use of regular block and regular plaster is the reason behind the rise of moisture from the lower floors because of the Osmosis property of high absorption materials, which leads to the Decoherence of plastering, salting of floors and walls, paint damage in addition to damage of electrical wiring.
The lack of dampness control leads to microbial growth in addition to growth of mold, bacteria, viruses as well as other microbiological organisms and its harm on human health.
Good insulation shall help to solve and eliminate the dampness problem and its sources including human metabolic processes, cooking, bathing, cleaning, and other human and nonhuman activities.
When exposed to a rainwater environment, the use of regular building stones and blocks leads to high dampness due to water absorption, which leads to wet walls inside the building and perhaps to infiltration of rainwater, and low efficiency of walls in thermal insulation ... which contributes to energy loss, low temperature of the interior walls, in addition to condensation of water vapor and growth of algae.
So, the modern construction resorted to the use of various traditional insulators, which are based on closing pores in walls, which leads to the absorption of dampness or water leaking inside the blocks of the wall and prevents leakage to the outside, which leads to the formation of dampness layer inside the wall itself and outside the insulation layer on the surface of the inner wall. With Duration, We see the plaster completely falling from the wall, where the dampness inside the wall has separated the plaster from the wall.

Using pozzolanic blocks and the thermal plaster in building shall absolutely prevent the formation of dampness.
Since the nature formation of neutral zeolite material, with low heat or cold effect, reduces water filtration and also shall prevent the formation of successive cold and hot surfaces caused by different temperature.
The important property of the pozzolana material is shown in the ion exchange and the surface porosity in addition to its high absorption ability which enables it to absorb the internal dampness and retains it by crystallizing it and re-release it if needed by the mediator, just like breathing process, which leads to the lack of internal dampness that does not exceed 30% when using pozzolanic blocks and thermo plaster.

Nowadays, People spend more than 80% of their time in an indoor environment, as there is a strong relation between the quality of this environment and human health and safety.
There is also a strong relation between health problems facing the human beings and the poor indoor environment in the building in which they live.
According to the World Health Organization (WHO), 30% of buildings in the world are sick or not healthy buildings, due to the fact that their inhabitants suffer from many diseases, whereas main causes are harmful emissions from used building materials, and pollutants from outside to inside the building.
That the internal air and what it causes of diseases and the extent of the impact of such diseases on human beings, which is known as the syndrome of buildings disease indoor air pollution, ie inside the buildings (offices, schools, companies, hospitals, etc.), is not less dangerous than outdoor air pollution and is considered the most dangerous for its direct impact on inhabitants who are living in buildings in where air contains contaminants at a concentration greater than permissible.
Volatile organic compounds, microbial contaminants, various gases, dust particles, indoor atmosphere in addition to lack of dampness control shall lead to the growth of mold, bacteria, viruses and other microorganisms that have a significant impact on the quality of the indoor environment.
The World Health Organization indicated that many of the microbiological substances contaminated of air are found in the indoor air including fungus mold, viruses, bacteria, pollen grains, bacteria and its derivatives.
Formaldehyde produced from processed and varnished wood, insulated foams and radon resulting from stones, cement, soil, water, fine dust and bacteriological materials due to poor ventilation and concentration of pollutants in a small space.

Using pozzolanic block with internal plaster of the same type (Thermo plaster), and as zeolite material has unique filtering properties, in addition to high ability to absorbing free ammonia and other unpleasant odors, and toxic and non-toxic gases. The high capacity of zeolite in ion exchange, especially with heavy metals, cationites, citronium 90, cesium 137, and other radioactive isotopes in addition to its retention and cracking through crystal formation.
It works as filters to refine gases, remove impurities such as Carbon monoxide, Carbon dioxide, Sulfur dioxide and water vapor, in addition to rebuild it to become pure air, based on the very important characteristic of the pozzolana in ion exchange and ammoniac selection so its ability to control the ammonia gas is very high by removing 97%. , in addition to the removal of nickel ions by 98.8% and lead by 57.4% as these metals break the ecosystem of those places so it is necessary to be removed. the low acid function accelerates the removal of contaminants mineral, using the inexpensive and safe ion exchange method, and reverse the expensive and unsafe methods Such as electrolysis, reverse osmotic pressure or chemical deposition.

Using pozzolanic block and Thermo plaster, taking into consideration the unique properties of pozzolana material (Surface Tension, Adsorption, and Ion Exchange), makes it unique for having such advantage in energy retention and energy re-release, whereas one meter of high porosity pozzolana material sprayed on a surface of 250 square meters will give an increase over any other material used in dampness preservation or adaptability with thermal exchange, so saving in using energy for heating and cooling purposes is up to 67% of the total used power (2 hour operation gives six hours extension).

Buildings are as any other thing on earth, are exposed to the stages of growth starting from the establishment, progress and then aged and vanishing and then the wheel of life spins again, and so on. The life span of any building depends on the nature of materials used in its establishment.


Elements that can negatively affect on a building

Solar radiation, rain, air pollution, dampness and rotting, the effect of ultraviolet radiation, heating and cooling processes and what it causes of expansion and shrinkage, movement and thermal shock between materials and surfaces, thermal inertia, durability and stiffness of building materials, differential movement between adjacent and different materials In the parietal section. Therefore, for sustainable and long-term construction, materials of construction must be of a nature and characteristics that avoid all the environmental problems that affect its sustainability.
Buildings and facilities which built using pozzolanic tuff, taking into account its previously mentioned properties and characteristics as an inert volcanic origin mineral (Non-chemically reactive), neutral inorganic and not affected by heat or cold or freezing, and does not decompose or disappear such as ordinary concrete or other organic material such as wood, Or rust like metal.
The fact that the pozzolana constitutes of millions microscopic vacuum cells actually make it a coherent and flexible mass at the same time.
Therefore, the possibilities of effectively adaptation and coexistence with the surrounding environment increases and works well to resist the occurrence of distortions, defects and cracks in the elements of construction. Through effectiveness of thermal conductivity and thermal shock, and expansion resistance through dampness, shrinkage through dryness and mechanical shock, permeability and neutral filtration. It reduces dead loads and maintains durability and stability even when climatic conditions change. It reduces side load and friction angles of buildings and surfaces, which reduces the process of corrosion in buildings and thus increases the life of the structures, so the life span of facilities built using pozzolanic blocks shall exceed more than 500 years.
For more than thousand years, people used pozzolana materials in building, such as the Church of Aya Sophia and Roman amphitheater in Rome, Marib dam in Yemen and many temples and palaces that still exist for this time, as it resisted all natural factors, including earthquakes.

The green or sustainable building increases of saving energy consumption, water, and material .This is the result of design that provides resources and reduces negative impacts on human health and the environment throughout the life cycle of the building, starting from its establishment, operation, renovation and removal.
Green buildings operate more effectively than traditional buildings. It can also save your money, increase employee productivity, improve your company's financial assessment, and help to demonstrate in your commitment to principle of sustainability.
Sustainable Architecture or Green Architecture, an architecture that relies mainly on the efficiency of the used materials and the natural materials in construction and finishing that are suitable for the surrounding environment. It does not produce elements that have adverse effects on the health of their users. It also depends on the design that takes into account the needs of people whether they are (healthy older, young people, women or children) or those who are deficient in their performance, so that this architecture is compatible with the requirements and directions of those who use it.
Construction using the pozzolanic block is considered as one of the most important achievements of green buildings. It is a 100% natural material with high properties in the values of thermal insulation and energy saving, non-toxic, inorganic, and resistant to pests and bacteria, It has a high ability to absorb odors and toxic gases, in which fungi, bacteria, mold, termites and other pests and insect cannot live in addition to that it is mite repellent. There are no residues in manufacturing processes, no gases or odors emitted, non-combustible, no side effects on human or non-human organism, no smoke or toxic gases in all its forms even in the case of a Fusion. In addition, during manufacturing process we does not use firing, it is also a long-term sustainable construction, whereas the life span reaches up to 500 years.

In addition, it is dampness resistant, works as an air or gas filter and removes nickel and lead ions, as these metals crash the ecosystem of those places so it is necessary to remove them and that the low acid function accelerates the removal of mineral Pollutants, using the inexpensive and safe ion exchange method.
U.S. Green Building Council depends in granting (LEED) certificate on all elements of construction. As the block consists 80% of the building area, so its importance is the same ratio.
Key standards adopted by the U.S. Green Building Council are sustainability, efficiency and saving in energy use, potential energy consumption, Positive effects on environment and human health in addition to local source raw materials, whereas all these requirements are achieved by using pozzolanic blocks.

The property of linking between silica particles and the elasticity property, non-shrinkage, degradation, and the structural composition of pozzolana with its low density. As it shows high flexibility for external mechanical affects such as shocks and vibrations, which makes it suitable for use in seismic active cities. It gives the building greater durability facing environmental variables such as earthquakes, soil erosion or landfall, because it possesses mechanical flexibility capable of absorbing, converting or dump the shock.
