STUDY OF MACRO LEVEL PROPERTIES OF SCC USING SILICA FUME AND FLY ASH BY USING ROBOSAND

One of the major environmental concerns is the disposal of the waste materials and utilization of industrial by products. Many power plants and electro static precipitators will produce millions of tons waste powder every year. Having considerable high degree of fineness in comparison to cement this material may be utilized as a partial replacement to cement. For this purpose an experiment is conducted to investigate the possibility of using fly ash powder in the production of SCC with combined use SILICAFUME and how it affects the fresh and mechanical properties of SCC. First SCC is made by replacing cement with SILICA FUME in 10% and fly ash powder is blended to mix in percentage like 25% as a partial replacement to cement. Here we use manufacture sand as fine aggregate. By taking fineness modulus 2.5,2.7,2.9 .Test results shows that the SCC mix with combination of 10% SILICA FUME and 25% fly ash powder with fineness modulus 2.7 satisfies filling ability and passing ability and hardened properties are also in the limits prescribed by the EFNARC
