It is composed of C4A3S (C4AF) and C2S as main minerals.
Characterized by higher early strength (The strength value at 3 days is equivalent to the strength at 28 days of Portland cement with the same grade) . The performance of impermeability, Frost and corrosion resistance is more excellent than those of Portland cement; It has a remarkable effect on restraining alkali aggregate reaction
CSA based cementitious materials is an ideal material for supporting and back-filling in mining construction, due to its high strength, adjustable setting time, good fluidity, especially for increasing the output of minerals such as coal and gold. SAC is also an excellent matrix for making special high performance engineering materials such as self-leveling material, grouting material and repairing material. As intellectual property rights of Yuanda Co. the manufacture technologies and products of SAC based materials have been exported to many countries.
