Calcium sulfo aluminate 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. CSA BINDER is also an excellent matrix for making special high performance engineering materials such as self-leveling material, grouting material and repairing material. Products of CSA BINDER based materials have been exported to many countries.
