Experimental study on Concrete when Cement is Partially Replace by Fly Ash, Wheat Straw Ash, Rice Husk Ash, Saw Dust 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, Wheat Straw Ash (WSA), Fly Ash, (FA) as a partial replacement for OPC in concrete[1]. The main aim of this work is to determine the optimum %( 10, 20, 30) of Rice husk ash (RHA), Wheat Straw Ash (WSA), Fly Ash, (FA), as partial replacement of cement for M40 grade of concrete[3]. In addition, results show that Rice husk ash(RHA), Wheat Straw Ash (WSA), Fly Ash, (FA), -/* (GP) as an artificial pozzolanic material has enhanced the durability of concrete.
