Experimental Study on the Mechanical Properties of Concrete by Partial Replacement of Cement with Rice-Husk-Ash & Marble Powder for M30 Grade of Concrete

Making and using of a sustainable concrete has become an important requirement day by day. To reduce the environmental effect, several of supplementary cementing and pozzolanic materials and mineral admixtures and chemical admixtures are introduced and they are partial replacement of cement in the concrete. This paper reports the results of the mechanical properties of the concrete with partial replacement of Partial replacement of Rice-husk-ash (0%, 5%, 10%, 15%& 20%, 25%) and marble powder (0%, 5%, 10%, 15%) separately and blended both rice-husk-ash and marble powder combines partial replacement (0%, 5%+5%, 10%+10%, 15%+15% & 20%+20%). The test results indicate that rice-husk-ash & marble powder is an effective mineral admixture, with 10% and combine of both (5%+5%) as the optimal replacement ratio of cement.
