Performance Evaluation of GGBFS and Rice Husk Ash based on Concrete Blocks

GGBFS mixing in Self-Compacting Concrete (SCC). Preceding research gives us information about the optimal use of GGBFS and RHA in mixture of concrete. Huge amount of CO2 is released into the atmosphere while manufacturing of cement which causes atmospheric phenomenon so Rice husk ash proofs to be a green product which is carbon neutral so its replacement of RHA and GGBFS deduct the emission of gases like greenhouse. Rice Husk Ash is material obtained from agricultural waste matter and it is present in excess in rice producing country like India and every one subtropical countries. By using of RHA there is a good impact on properties of OPC. On burning the rice husk under uncontrolled temperature, highly reactive RHA is obtained and ash was used as additional cementing material. This paper gives mainly the knowledge about compressive, tensile, flexural strength gain efficiency of Rice Husk Ash (RHA) and strength concretes imparts initial strengths and also indicate about later strengths of GGBFS. During this paper we are able to conclude that by doing variation in the proportion of GGBFS for assessment of compressive strength. it absolutely was seen that up to 30% replacement of RHA and 45% replacement with GGBFS in the concrete will yield good increase in the strength.
