1980s. Since then, the market share of SCC has rapidly increased in precast applications or for ready-mix concrete applications, due to a number of economic opportunities and the improvement in the work environment associated with its use. SCC has been successfully used in North America in the precast industry. A recent overview on SCC types, test
Preparation and properties of ready-to-use low-density
Foamed concrete is widely used as a highly energy-efficient building material. However, low-density foamed concrete requires increased amounts of Portland cement or steam curing to meet engineering requirements. This is due to inadequate compressive strength and long setting time of Portland cement.
