A Review on Properties of Self Compacting Concrete using Bagasse Ash

Abstract

Where the placing and compaction of concrete are difficult (such as structural element jacking, filling near retaining structure) self-compacting concrete play a vital role in these condition. Self-compacting concrete (SCC) is widely used where the ability of flow and self-compaction is required. Main benefit of these concrete (SCC) is to save labour cost and minimize the construction time. In the view of materials, there is slightly different from commonly used material for construction. The coarse aggregate used in SCC is taken less i.e. up to 50 per cent. Bagasse ash is used as a partial replacement for cement. The research work is done, by considering the variation of water cement ration from 0.25 to 0.35 and the percentage of bagasse ash varies from 10 to 20 per cent. For defining the flow-ability of SCC slump test, V –funnel, U-box test and L- box test had conducted. The value of horizontal slump flow varies from 560 to 760 mm. The flow time in V- funnel test varies from 8 to 12 second is taken satisfactory.When the bagasse ash is used up to limited range from 10 to 20 per cent slump flow gradually decreases but when super plasticizer is used there will be improvement in slump flow. By the use of bagasse ash the compressive strength will also increase at lower w/c ration 0.275 and with 15% bagasse ash. When we further increase in the bagasse ash per cent there is very less increase in compressive strength.
