Description

High-efficiency CSA Expansive Agent or csa cement additive is another application of our CSA BINDER. It is obtained by blending our CSA binder (clinker) which consists essentially of calcium sulphoaluminate and CaO. High-efficiency CSA expansive agent is always mixed with ordinary cement. When mixed in the proper proportions with ordinary cement and hydrated, cement mortar or concrete expands during the early stages of hydration. This expansion, when restrained, makes it possible to minimize drying shrinkage. Moreover, when the ratio of High-efficiency CSA Expansive Agent to ordinary cement is increased its high expansion qualities make it ideal for use in prestressed concrete.
High-efficiency CSA Expansive Agent is being used in all sections of the construction fields and by a wide variety of concrete products manufacturers.

The properties of High-efficiency CSA Expansive Agent conform to the standards of the manufacturer and to the Chinese relevant standards.
1.Low alkalinity. High-efficiency CSA Expansive Agent has a very low alkali content (R2O0.3%) which is beneficial to avoid AAR in concrete.
2.Short stable stage of expansion. The stable stage of expansion is not more than 14 days, thus the ultimate strength of concrete is not affected.
3.Low dosage and high expansion capacity. The normal dosage of High-efficiency CSA Expansive Agent is 6~8% by the weight of ordinary cement, which is lower compared with other expansive additives such as UEA and CEA (their dosages are about 10~12% by the weight of cement) in the market.
Our exporting quantities for the CSA cement and calcium aluminate cement is around 30000 mts per year.
Our refractory products include refractory bricks and mortars, insulating bricks and some auxiliary materials for iron, steel and foundry such as calcium aluminate slag and carbon raisers. >
