Abstract :
Light weight construction is one of modern topics in civil engineering, the topic of reducing weight of structure is achiev by use of new technique and optimization of construction procedure. Consideration to wide use of concrete and enviromental pollution to the reason of using cement, investigators are trying to replace a part of cement by natural and artifitial pozzolan and nano particle materials. In this study the use of natural pozzolan zeolite with different percents 0, 5, 10, 15, 20 investigated and longterm and short term effects on the compression and tensile strenght on semi light weight concrete at the age 3, 56, 90 days were studied and compared with control specimen. Result shows that 5% and 10% replacement of zeolite improve compression strength at the age of 3, 90 days, and for age of 56 days most improvement is related to 15% replacement by zeolite.
