MECHANICAL PROPERTIES OF HIGH PERFORMANCE CONCRETE INCORPORATING RICE HUSK ASH

R. Dharmaraj

Abstract :

 In the present investigation, a feasibility study is made to utilize the rice husk ash as an mineral admixture  in HPC and to investigate the mechanical properties of concrete. The properties of cement, fine aggregate, coarse aggregate and water for M60 grade concrete is arrived as per ACI 211.1–91. HPC mixes incorporating  different percentages of RHA by weight of cement along with some suitable super plasticizer. OPC was replaced with  RHA by weight at 0%, 2.5%, 5%,7.5%, and 10%. w/c ratio between 0.35. Slump flow test was carried out on fresh  concrete were prepared to have a slump between 175– 225mm while Mechanical strength properties was carried out  on hardened 150 mm concrete cubes after 3, 7, 14 and 28 days curing in water. The results of the study indicate that  the Mechanical properties of HPC mixes improved by incorporating RHA up to a desirable content of 7.5% by weight  of cement.
