Ecological was damaged due to quarrying caused depletion of natural resources (limestone, iron ore, clay). Many researchers proving that these by-products have pozzolanic properties which improve the quality of concrete. Global production of rice husk is approximately 580 million tonnes a year and this is rising as the world population and consumption of rice increases. This paper reports the effect of rice husk ash (RHA) grinding time on the workability and strength of concrete. Concrete mix proportions were introduced with RHA and superplasticiser (Sp) as additives. Three RHA with different ineness, i.e. RHA1(5) Sp, RHA2(5)Sp and RHA3(5)Sp were used for study .Based on analysis, it is found that the increasing of ineness decreases the workability but increases the compressive strength of the concrete. The use of RHA3(5)Sp results in highest strength at 28 days, which is due to the better dispersion and illing effect as well as an increase in pozzolanic reaction. From the research, it is shown that RHA has the potential to be a cement replacement material. The research has an important implication on environmental for sustainability due to usage of waste product as construction material. 2016-01-19T09:34:35Z 2016-01-19T09:34:35Z 2015-07 Other The Journal of the Institution of Engineers, Malaysia, vol. 76(1), 2015, pages 47-51 0126-513X http://dspace.unimap.edu.my:80/xmlui/handle/123456789/40757 en The Institution of Engineers, Malaysia (IEM)
