Abstract

Micronised Biomass Silica (MBS) is an agricultural waste product which comprises of high content of silica. This study was conducted on the off-white amorphous biomass silica ash derived from the rice husk with pozzolanic index 69%. Various percentages of MBS ranging from 0% to 20% by mass have been used as cement replacement material. Compressive strength and water permeability of concrete with MBS incorporation were investigated. From the results obtained, it was identified that up to 12% of MBS is able to produce concrete with higher strength and lower in water permeability compared to control concrete.

Uncontrolled Keywords:micronised biomass silica, pozzolanic index, compounds possessing cementitious properties. Recently, pozzolanic material like fly ash, silica fume and ground granulated blastfurnace slag has been widely used in construction industry. Moreover, pozzolanic material has some benefits such as it can encourage the application of natural waste product and for environmental conservation [2]. This is because; generally pozzolanic material is produced from by-product waste. Normally these pozzolanic materials functioning as cement replacement material which substitute a part of cement content. In this study, Micronised Biomass Silica (MBS) is produced as cement replacement material. Various percentages of MBS are used to produce the concrete. Thus optimum percentage of MBS is recognized. On the other hand, compressive strength and water permeability were conducted as measurement of MBS concrete's performance. compressive strength, water permeability
