Mechanical Characteristics and Durability of Self-Compacting Concretes Produced with Roof Tile Powder

Abstract

Bad reinforcement concrete works could generate building failures after earthquake. Concrete pouring and compacting on structural element with dense reinforcement and beam column joint are difficult. Compaction and pouring of concrete on element of structure with dense reinforcement and structural joint like beam column joint are difficult. Many types of concrete have been developed to enhance the different properties of concrete. When huge amount of concrete of very high steel is to be placed in a reinforced concrete member, it is very hard or difficult to ensure that the form work completely filled with concrete that is, fully compacted without voids or honeycombs. 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 40% i.e. (0%, 10%, 25%, 30% and 40%). The super plasticizer and viscosity modifying agent are 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, L-shaped box and U-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.
