Abstract :

Abstract This paper presents the results of a laboratory study carried out on effect of using microsilis and air entrain on compressive strength of light weight perlite concrete. In this study, 63 test specimens with different percentage and mixtures including microsilis and air entrain were used. 63 test specimens including microsilis were also prepared for comparison purposes. Laboratory test results showed that workability and compressive strength can be increased, and density can be decreased by the use of air entrain and microsilis. These results showed that concrete mixture incorporating 0.5% air entrain and 10% microsilis can be optimum case
