Abstract :

Considering that the weight of the structure increases the forces involved, especially the lateral forces such as earthquakes, so for this reason, as far as we can take the building path, we have been able to withstand earthquake resistance to the structure. Since, one of the commonly used methods for producing the light eight concrete, utilizes the light weight aggregates with significant role in the concrete strength, proposing the optimized mix-design for the light weight concrete appears to be important. The result of experiments on 140 samples are representative of achieving to structural lightweight concrete according to ASTM C330 Standard which limits the specific gravity of structural light weight concrete to 1850 kg/cm3 and limits the minimum compressive strength of structural lightweight concreteto170 kg/cm3.  Specific gravity and compressive strength of samples could be reached to defined limitation according to ASTM C330 Standard by using the very little particles of pozzolans and by changing in mix design
