Abstract

Research aim: nowadays by increasing dimensions of structures, engineers face with increasing weights of structures. It effects structures in several ways and makes designing challenges. The first danger of weight increasing in structures is addition of lateral forces. This impose very high hazard and due to resistance it, the designer must use heavy elements which makes growth in cost. So by researching to lighten, we can discount the earthquake damages. By using light elements in structures, engineers will able to rebate dead loads and lateral forces which leads to less financial and safety damages.Since most structures are made of concrete or a mix of steel and concrete, so lightening the concrete will be very useful. Light concretes are insulators of thermal and sonic in addition of being light. Research method:In this text, structure of light perlite concrete has been studied and tried using perlite seeds obtain a low weight concrete with admissible strength and suitable density to use in structures as light concrete. Also we have used different additive materials to increase compressive resistance and decrease density of the concrete. In this text we have used 264 samples with different admixtures has been tested. Steam bath curing has been used for all samples. Results: using micro silica more than 12 weight percent of concrete has no excellent effect on strength of concrete. Conclusion :using micro silica with super plasticizer increases pressure resistance of concrete .
