What is pozlana?
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.
ينتمي الزيوليت إلى عائلة المجسمات الرباعية الوجوه ذات البنية ثلاثية الإبعاد , ذات الشحنة السالبة , ويتميز الزيولايت بالتبادل الشاردي ومسامية الانتقالية للسطح وحمضية السطح , ويضم مجموعة من معادن الألومينوسيليكات القلوية والكلسية التي تحتوي شبكتها البللورية على ذرات من الماء فيه , وينشأ الزيولايت الطبيعي نتيجة التفاعل بين الماء المسامي ( المتواجد فى الشبكة البللورية ) وبين الزجاج البركاني أو معادن السمكتايت والفلسباروالبلاجيوكليزوالنيفلين أو السيليكا . ويتحقق التبلور عند وجود نسبة عالية من المغنيزيوم والهيدروجين إلى نسبة الصوديوم – البوتاسيوم – الكالسيوم ، بحيث يتوقف نوع الزيولايت المتشكل على طبيعة الصخور التى انحدر منها ودرجة حرارة الماء وضغط النشاط الأيوني

How can pozzolan bricks resist heat and maintain moderate temperatures, thus saving energy? .
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.
How to insulate and absorb the walls and ceilings built of pozzolana sound?
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.
Does pozzolanic bricks constitute a barrier to impermeability or exchange of water vapor or moisture to and from the external walls?
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.
Is it required in the construction process special labor trained to build this type of bricks?
