Experimental Study of Sustainable Concrete by Partial Replacement of Cement with Rice Husk Ash

Different materials with pozzolanic properties such as fly ash. Condensed silica fume, blast furnace slag and rice husk ash have played an important part in the production of high performance concrete. During the late 20th century, three has been an increase in the consumption of mineral admixture by the cement and concrete industries.[4] The increasing demand for cement and concrete is met by the partial replacement for energy intensive Portland cement. Pozzolanic materials have long demonstration their effectiveness in producing high performance concrete. Artificial pozzolanas such as supplementary cementing material in many part of the world.[2] This work evaluates the compressive strength of rice husk ash (RHA) as a partial replacement for PPC in concrete.[1] The main aim of this work is to determine the optimum %( 0, 8, 10, 12, 14, 16) of (RHA) as partial replacement of cement for M35 grade of concrete. And also effect of super plasticizer on mechanical properties. [3] In addition, results show that RHA as an artificial pozzolanic material has enhanced the durability of RHA concrete.
