Study of Behaviour of SIFCON Produced By Partial Replacement of Cement with Glass Powder and Low Tensile Strength Steel Fibre

Slurry Infiltrated Fibrous Concrete (SIFCON) is a special type of fiber reinforced concrete (FRC) which have large amount of fiber. FRC contain fiber only 2% to 5% by volume of cube because of balling and clustering problem but in SIFCON we can use fiber from 5 to 20 % of volume of cube. Since SIFCON is a ductile layer of high performance fibre concrete with significantly large amount of fibres, hence it can also be used to reduce the wear and tear. However, it is applied only in relative thin layers; hence SIFCON does not perform any load bearing function. Glass is a hard brittle, noncrystline more or less transparent substance produced by fusion, usually consisting of mutually dissolved silica and silicate that also contain soda and lime. Glass can be considered as an environmentally friendly material because it can be recycled several times and can be used in many applications. According to estimation several million tonne of waste glass are generated worldwide annually. Waste glass contain high silica (SiO2) due to which when these waste glass is ground to very fine powder react with alkalises in cement and form cementitious product that help in strength contribution. In this research work we are going to use 6%,12% and 18% of steel fiber by volume of 150mm× 150mm× 150mm cube to find out the optimum strength and compare it with the strength of SIFCON produced by partial replacement of cement with glass powder at the days of 7days,14days &28 days. This research therefore is an comparison of the performance of the control SIFCON concrete made of 6%,12% & 18% of steel fiber and SIFCON produced by partial replacement of cement with glass powder. In this work 5%, 10%, 15%, 20% and 25% Glass powder is replaced by weight of cement.
