Study on Rice Husk Ash as a Partial Replacement of PPC Cement (Fly Ash based) in Concrete

Different materials with pozzolanic properties such as fly ash. Condensed silica fume, blast furnace slag and rice husk ash have played an important role in the production of high performance concrete. During the late 20th century, there has been an increment in the use of mineral admixture by the cement and concrete industries.The increasing need for cement and concrete is filled by the partial replacement for energy intensive Portland cement. Pozzolanic materials have long proven their strength in developing high performance concrete. Artificial pozzolanas such as supplementary cementing material in many sections of the globe.This work evaluates the compressive strength of rice husk ash (RHA) as a partial replacement for PPC in concrete.The main objective of this study is to find 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. In addition, results show that RHA as an artificial pozzolanic material has enhanced the durability of RHA concrete.
