Abstract
Concrete is the important construction material. The major component of concrete is cement which produces huge amount of carbon di oxide at the manufacturing stage of cement. The cement can be replaced partially by various by-products like fly ash, nano silica, micro silica, etc. The fly ash has been replaced to cement by 20%, in M40 grade of SCC. The micro silica and nano silica are replaced at 5%, 10%, 15%, 20 and 1%, 2%, 3% and 4% respectively. The flowability of fresh concrete as suggested by the European Federation of National Association Representing for Concrete guidelines was tested on slump flow, V-funnel, Orimet and L-box. The influence of micro and nano silica on the flow characteristics was evaluated. For the present study, the SCC mix was prepared for M40 concrete and the fresh concrete test was performed on control SCC, micro-silica and nano-silica replaced Self-compacting concrete. The compressive strength as mechanical property of SCC has been tested.
