Bluey CSA Cement

2020-9-27  Calcium sulphoaluminate (CSA) cement is a blended, hydraulic, ultra-high-performance cement. Its main component is calcium sulphoaluminate cement crystals. Bluey use CSA as a source of calcium aluminate instead of the traditional high-alumina cement to react with calcium sulphate in the presence of lime to form ettringite, which is what CSA cement in its crystal form is widely known as.

The advantages of C.S.A. cement - Caltra

2016-11-11  CSA cement is considered to be a green binder because of the following factors: 1. CSA cement is calcined at 1250oC (2250oF) whereas Portland is calcined at a temperature of 1500oC (2700oC). 2. CSA clinker is much softer compared to Portland clinker, which reduces the energy requirement during grinding. ...

Calcium Sulphoaluminate - an overview ScienceDirect Topics

Calcium sulphoaluminate cements Raw mixes for calcium sulphoaluminate (CSA) clinkers differ from those for OPC in that they contain significant amounts of sulphates. The CSA clinker is mainly composed of yeelimite (4CaO 3Al 2 O 3 SO 3), belite (C 2 S) and an Al-rich ferrite (Andac and Glasser, 1995).
