Self Consolidating Concrete Overview of SCC Concrete

SELF CONSOLIDATING CONCRETE CONSTRUCTION Construction is where SCC really shines What could be better than a mix that consolidates itself eliminating all vibration lift lines and bugholes For flatwork SCC mixes can be described as self leveling while formed concrete can be self placing Here are a few tips on construction with SCC

Production and placement of self compacting concrete

Self compacting concrete is highly susceptible to a small fluctuation of water content in the mixture design than traditional concrete The changes in the moisture content of aggregates especially in fine aggregates can considerably affect the rheology strength and durability of SCC Shen et al 2015; Poon et al 2004 Excess water in an SCC
