Calclium sulphoaluminate (CSA) cement based self leveling concrete, Param 5500 offers significant benefits over Portland cement based self leveling concrete. CSA cement is close to 60 per cent greener than Portland cement. CSA cement is fired at a much lower temperature than Portland cement, producing 62% less carbondioxide during their manufacture. Unlike Portland cements CSA cements do not produce calcium hydroxide, and that reduces problems like cracking, curling and efflorescence.
Many concrete countertop contractors are shifting to Calcium Sulphoaluminate Cements (CSA) because the time savings offset the higher cost of CSA versus Portland cement. CSA cements exhibit higher flexural and tensile strength, and it’s harder. Calcium aluminate cements are resistant to high temperatures, sulphates, weak acids, and seawater.
