Compressive, flexural and splitting strength of fly ash and silica fume concrete

Abstract Cement replacement materials are commonly used in concrete technology. Several researchers have examined high-performance after adding mineral admixtures to it, but further studies still needed provide the optimum dosage of these for instance fly ash and silica fume. This study compares three types mechanical properties (compressive strength, flexural splitting tensile) at age 28 90 days. The test results designate that affects all tested types. However, fume is more operative than ash. Furthermore, same type slightly improves properties.
