Performance of Roof Tile Powder as Partial Replacement of Cement in Self Compacted Concrete

Abstract

The delegated concrete works could promote structure failure after earthquake. Compaction and pouring of concrete on element of structure with dense reinforcement and structural joint like beam column joint are difficult. So the self-compacted concrete is a better solution for this problem. Use of self-compacted concrete that has flow ability, filling ability and passing ability is better than the normal concrete. On this research using of roof tile powder in self-compacted concrete give better workability and also strength of self-compacted concrete. The roof tile powder is easily available in Indian villages. The possibility of using roof tile powder (RTP) with fly ash for partial replacement of ordinary Portland cement (OPC) will explore in this research. An experimental study is made by preparing specimens by utilizing roof tile powder (RTP) as partial replacement of ordinary Portland cement in Self compacted concrete with a percentage replacement from 0% to 50% i.e. (0%, 10%, 25%, 30%, 40% and 50%) . The super plasticizer is added in Self compacted concrete. Test on fresh concrete is slump spread for all trial mixes. The mix that has the largest slump spread is tested with V-funnel and L-shaped box. Conventional specimens are also prepared for M30 and M35 grade Concrete without using RTP and fly ash. By conducting tests for both the specimens the properties of concrete will be investigate. This study ensures that using of roof tile powder (RTP) as partial replacement of ordinary Portland cement substitutes in concrete gives a good approach to reduce cost of materials and will accomplish the better properties of self-compacted concrete at all ages.
