Abstract

In this article, 2 sources was studied , rich in reserves, pumice and zeolite’s effects on elasticity modulus which is an important criterion of high strength concrete (HSC), for this reason, HSC was produced by pumice and zeolite’s replacement for the concrete in proportion of “0, 5, 10 and 15%” to the binder mass. Deformation controlled compressive strength tests was performed on concrete samples to determine elasticity modulus. We have formed the mathematical model equations using the stress strain data obtained from the deformation controlled compressive tests. The elasticity modulus was determined for each concrete type using the secant method on model equations graphs. The elasticity modulus was also determine using some empirical equations and the relation between 2 groups of data. As a result, there is decreasing ratio of pumice replacement with increasing quantities of zeolite in high strength concrete and effects of modulus elasticity is positive in all stages of concrete age.

 

Key words: High strength concrete (HSC), pumice, zeolite, modulus of elasticity, mineral admixture.
