Abstract
Making and utilizing of a sustainable concrete has become an important requirement day by day. To reduce the environmental effect, several of supplementary cementing and pozzolonic materials are introduced and they are partial replacement of cement in the concrete. In this work I am using two waste materials in this work namely marble powder and Rice husk ash as partially replacing with cement. Marble powder and rice husk ash both materials cheaply available in the India. Cement production creates environmental problems and marble powder as well as rice husk ash creates environmental problems.so Marble powder and Rice husk ash as partial replacement with cement in concrete. This Project reports the results of the mechanical properties of the concrete with partial replacement of marble powder (0%, 5%, 10%, 15% & 20%). Partial replacement of Rice-huskash (0%, 5%, 10%, 15%& 20%) separately and blended both marble powder and rice-husk- ash combines partial replacement (0%, 5%+5%, 10%+10%, 15%+15% & 20%+20%). The test results indicate that marble powder & rice-husk- ash is an effective mineral admixture, with 10% and combine of both (5%+5%) as the optimal replacement ratio of cement. Flexural strength and Tensile strength will be maximum at 15% replacement of both supplementary materials (Marble powder, Rice husk ash).Beyond 10% marble powder and rice husk ash the compressive strength of concrete reduces and is lower than that of control concrete.
