Lightweight construction is one of the new topics in building science, which means reducing the cost of the building by using new techniques to build new materials and optimizing execution methods.
The growing need for the building and the need to use new materials and methods to increase the speed of construction, increase the useful life and also make the building resistant to earthquakes. Solving problems such as long construction time, low useful life or high cost of construction requires the provision of solutions for practical use of new methods and new building materials to reduce weight and reduce construction time, more durability and ultimately reduce the cost of construction. Lightweight construction is one of the new topics in building science that is expanding and progressing day by day. This technology is to reduce the cost of the building using modern techniques of making new materials and optimizing execution methods. In addition to saving time and energy, reducing the weight of the building reduces the damage caused by natural disasters such as earthquakes and minimizes the damage caused by the high weight of the building.
According to research, it is possible to obtain compressive strength at the level of structural strength by using lightweight concrete containing Leica. The use of microsilica in the manufacture of lightweight concrete samples increases the compressive strength. The use of microsilica reduces the volume absorption and capillary absorption of lightweight concrete containing Leica. 90-day shrinkage of lightweight concrete containing Leica using micro-silica is less than the control sample. In general, due to the abundant sources of clay in the country, it is also recommended to study the technology of making Leica grains and light structures and light concrete slabs containing Leca on a larger scale, and instructions and standards for using Leica to be developed in the construction industry.
