Abstract :

This paper aims of studying and analyzing the various properties of concrete by partially replacement of Cement by Rice Husk Ash (RHA). It obtains from burning of outer cover of rice husk. It consists of non-crystalline silicon dioxide (SiO2) with high specific surface area and high pozzolanic reactivity. The Rice Husk Ash can be found as natural materials, by-products or industrial wastes chemical properties so far closer to micro silica, silica fume. The result revealed that the compacting factor decreased as the percentage replacement of PPC with RHA increased. Replacement of cement by rice husk asks showed in M25 grade concrete compressive strength improvement at the replacement of 10% in all Ages. From this entire experimental work & studies it is concluded that mix M2 (M0+10%RHA) is the best combination among all mixes, which gives max compression strength over normal concrete.
