Pozlana is a natural, inorganic substance, formed through ancient times under the influence of hot mineral waters from volcanic eruptions. It is known as zeolitic tuff, which represents a series of alkaline elements, alkaline earth minerals and hydrated aluminum silicate, whose minerals are most present in sedimentary rocks of volcanic origin with high porosity in which the volume of The porous voids account for 50% of its total volume, light in weight, and zeolite is considered the least dense mineral among all the quaternary silicate minerals, very hard, and the size of the grains is small, and it has a high susceptibility to hydration. From water, it is easy to separate and adhere to the crystal system without affecting it, and there are more than 30 types in nature.
Zeolite belongs to the family of tetrahedrons with a three-dimensional structure, with a negative charge. It is characterized by ion exchange, transitional porosity, surface acidity, and surface acidity. It includes a group of alkaline and lime aluminosilicate minerals whose crystal lattice contains atoms of water in it. Natural zeolite is formed as a result of the interaction between water. Porous (found in the crystal lattice) and between volcanic glass or smectite minerals, feldspar, plagioclase, nepheline, or silica. Crystallization is achieved when there is a high ratio of magnesium and hydrogen to the ratio of sodium - potassium - calcium, so that the type of zeolite formed depends on the nature of the rocks from which it descended, the temperature of the water and the pressure of ionic activity.
Building with bricks or pozzolanic concrete is very old, as many ancient buildings were built from it, such as the Church of Eila Sophia and the Roman amphitheater in Rome and many temples and palaces in Britain, which needed high-level architecture and during the past ten years, construction began with this type of bricks in Saudi Arabia in buildings Al-Haram Al-Sharif, Jeddah Gate Towers, the Arab Complex Project, King Abdullah University of Science and Technology, the Ministry of Defense and Saudi Aviation, the Electricity Company and many other buildings. In Jordan, King Hussein University, Al al-Bayt University and many private villas and apartments
The thermal conductivity of bosonian bricks is 0.18 for hollow bricks, 0.28 for solid bricks w/m2k
Thermal resistance is the inverse of thermal conductivity, and thermal conductivity is the heat current (in watts) passing vertically through a unit area of a surface of a material medium, thickness and unit length, due to the difference in temperature between a surface of one degree Celsius and a unit of measure (watts/meter.°C). . Thermal resistance is the ability of building materials to heat flow, and the higher the resistance, the better the insulation materials. The thermal resistance of pozzolanic bricks is 0.0555 per cmᶾ and this gives the advantage of low thermal conductivity and low permeability in addition to the moisture content that does not exceed 3% of its weight.
From 0.3 mm to 0.1 mm
All thicknesses of traditional bricks and plaster, in addition to other thicknesses
The weight of the cubic meter of pozzolanic absorbent bricks is 1400 kg and the hollow bricks are 725-825 kg, which is 40% less than that of traditional cement bricks.
The breaking strength of the pozzolanic bricks reached 4 Newtons after 28 days and increased to 6 Newtons after 90 days
The pozzolanic bricks are only used in automated factories, where the pozzolanic bricks are manufactured under a central pressure of up to 280 bar per square meter and a shaking force of up to 5000 revolutions per minute, in addition to the chiving that takes place in special rooms.
The construction of pozzolanic bricks is carried out in the same way as the construction of traditional bricks
Yes, the construction with pozzolana products is more durable than the construction with traditional concrete. Studies have shown that the life span of the pozzolana construction is more than 500 years, while the construction with ordinary concrete does not last more than 60 years.
Yes, the pozzolanic brick construction is designed for high buildings, since the weight of pozzolanic bricks is reduced by up to 45% than the traditional bricks, so it is perfectly suitable for high buildings and reduces dead loads and maintains the durability and stability of the foundation..
The high durability of pozzolanic bricks makes it suitable for high, medium and small buildings, where the durability reached 10 Newtons, which makes this type of bricks a carrier and an insulator.
The manufacturing mechanism is based on automated production in all its stages, starting from mixing pozzolana paste with cement and water, by screw and cylindrical mixing method, through the automatic hydraulic presses, to the drying rooms.
Pozzolanic bricks are used in all aspects of modern and traditional construction, as it is an alternative to traditional cement bricks, for hospitals, hotels, restaurants, industrial complexes and schools, wedding halls, conference halls, mosques, churches, apartments, palaces, villas, cold rooms, fireplaces, furnaces, melting furnaces, and others, and high-rise and ordinary buildings. :
Heat insulation, fire resistant, mold and bacteria resistant, moisture resistant, light weight, sound insulation, low cost, high durability, environmentally friendly, long-term construction. Resistant to salts and sulfates, resistant to cracking and corrosion.
The pozzolanic brick and its properties in terms of durability and durability of the concrete structure, it combines the characteristics of durability, thermal resistance, lightness of weight and sound insulation in one product in addition to that it is inorganic, does not rot, is resistant to pests and is not degradable in addition to its high resistance to fire, so it is the best choice for walls and ceilings.
One of the advantages of the pozzolanic bricks is that it combines the pozzolanic plaster or the traditional ordinary plaster of the walls and ceilings built from it, in addition to its unified sizes and the rough surface and the pozzolanic hyphen makes its adhesion to the plaster or stone at a high level. Which makes the construction section an integrated unit to achieve the highest benefit from this construction.
The use of pozzolanic bricks and the strength and durability they contain make it an ideal holder for shelves, weights and side loads that are placed on it (three times the normal bricks), in addition to the feature of not cracking during the placement of nails or door and window hinges
The manufacture of pozzolanic bricks and concrete in Jordan was not known in previous years, except to very narrow limits. This is due to the lack of knowledge of the characteristics of pozzolanic tuff in concrete, the lack of a large mechanical industry, and the lack of interest or knowledge of the relevant official authorities in this product, despite the presence of a huge reserve of this material In more than one area in Jordan
Pozlana is a completely harmless natural material. It is inorganic, non-combustible, odorless, non-toxic, and has no side effects on human or non-human beings. It does not emit smoke or toxic gases in all its forms. In addition, it works as a filter for air or gases. And the removal of nickel ions by 98.8% and lead by 57.4%, as these metals destroy the ecosystem of those places, so it is necessary to remove them, and the low acidic function accelerates the removal of metal pollutants, and by the inexpensive and safe ion exchange method and the opposite of unsafe and expensive methods such as Electrolysis, reverse osmotic pressure or chemical precipitation
All the measurements of the pozzolanic bricks are identical to the measurements of the bricks and concrete, in addition, there are additional measurements of the pozzolanic bricks and mortar, such as the 60 cm rib.
Yes, it is a charity for the environment, and it is considered one of the most important achievements of green buildings. It is non-toxic, inorganic, resistant to pests and bacteria, and has a high ability to absorb odors and toxic gases. No fungi or bacteria live in it. Natural heat and sound
Pozzalana is an inert material that is not affected by heat, cold or freezing, and does not decompose like ordinary concrete or other organic materials such as wood or rust like metals.
The property of bonding between silica particles and the property of non-shrinkage and decline and the structural structure of pozzalana with its light weight, it shows high flexibility to external mechanical influences such as shocks and vibrations, which makes it suitable for use in seismically active cities. Therefore, the Church of Eilat Sophia and the Marib Dam have resisted earthquakes more than once.
The thermal insulation property of pozzolana comes from being an inert material and containing micro-air cavities, which is a poor conductor and highly heat-resistant, so it reduces the consumption of cooling or heating energy for buildings by up to 65% in addition to the ability to renew energy and this ability is unique to zeolite as a cubic meter Of zeolite spread on an area of 250 square meters will give 60% more than any other material used in moisture preservation or adaptation by heat exchange.
The ability of the pozzolana material to absorb sound and curb the mechanical vibration energy comes from the nature of the sub-pozlana material, which constitutes more than 60% of its volume, so it leads to reducing the noise inside the building from the outside and vice versa, and the echo frequencies in the great halls and preventing the transmission of vibration and sounds of the machines where it reaches The sound insulation is up to 50 dB and has a high ability to absorb comprehensive noise and includes all annoying and unwanted sounds resulting from the external environment and transient noise, which is continuous and continuous noise that breaks after a period of time and is replaced by other sounds after a short period (trains, planes, cars Pulsed noises, which are all annoying and unwanted sounds that follow at short intermittent periods and are more effective on humans because their level is high. The efficiency of the walls in blocking noise transmission depends on their mass, the thicker they are, the better at preventing noise transmission.
The nature of the formation of the neutral zeolite material, which has a low impact by heat or cold, leads to a reduction in water filtration and prevents the formation of successive cold and hot surfaces resulting from different temperatures, and its high capacity for ion exchange, especially heavy metals and cations, and the elements strontium-90 and cesium-137, And other radioactive isotopes and their retention in the crystal formation, and cracking, they act as filters to purify gases and remove impurities such as carbon dioxide, sulfur dioxide and water vapor, and rebuild it, to become natural air, which leads to a lack of internal humidity, which does not exceed RH 0.30 in In the case of using the Pozzolanic plaster, while the construction is in traditional bricks, the internal humidity is more than 0.76 RH. The mechanism of action of the pozzolana material, which allows the penetration of micropores, achieves a healthy balance between moisture resistance and the diffusion of water vapor in closed atmospheres and prevents the infiltration of moisture from the outside to the inside.
The construction of this type of bricks does not require special trained labor, but rather the construction process of traditional brick builders, which will save him a lot of time due to the light weight of the bricks and the ease of construction
In the same way as for traditional bricks, it is preferable in this type that the bricks are not broken horizontally or vertically, but only the two ends of the bricks are broken from the top and the bottom to pass the wires in the internal brick channels, so that it does not have a large seamless area, which loses the full homogeneity of the wall.
Pozzolanic bricks are manufactured from 100% natural material, which is an inorganic material, with high properties in thermal insulation and energy saving values. Duration (life span of 500 years), as it does not grow in Bacteria, mold or termites and other pests and repellents to insects and mice.
The American Green Building Institute relies on granting the LEED certificate to all building elements, and since bricks constitute 80% of the building area it is built from, so its importance is in the same proportion. Positive effects on the environment and human health, locally sourced raw materials, and all these conditions are achieved by pozzolanic bricks.
Yes, it is possible, but it is preferable that the entire building be made of Bozinian bricks to achieve the highest degree of benefit from this type of bricks
