Properties of glass fibre reinforced self compacting concrete

Self Compacting Concrete (SCC) is a concrete that is able to flow under its own weight and completely fill the formwork, even in the presence of congested reinforcement, without any compaction, while maintaining homogeneity of the concrete. The elimination of compaction for SCC is beneficial in solv...

description Self Compacting Concrete (SCC) is a concrete that is able to flow under its own weight and completely fill the formwork, even in the presence of congested reinforcement, without any compaction, while maintaining homogeneity of the concrete.
