Abstract

Currently high-strength concrete is increasingly used in modern concrete technology and particularly in the construction of high rise buildings. This study has been conducted to investigate the properties of high-strength concrete that was produced by using stone powder (SP) as an alternative of proportion on cement after being processed , since its main oxides are similar to those of cement.
The aim of the research is to study the effect of (10,15,20,25)% stone powder as replacement of cement, used in concrete mix which it has a mixing proportion of (1:2:1.8;w/c=0.26), and it is shown their effect on some of mechanical properties(compressive strength, splitting tensile strength, and flexural strength).
The test results showed clear improvement in some mechanical properties of concrete by using 20% (SP). The increment where its ratio (34, 41, 34.4)% for each compressive strength, splitting tensile strength, and flexural strength compared with reference mixture for the same duration respectively.
