China [CN] The CSA Cement is not a cement,we usually call it CSA binder or CSA Cement Clinker.It main raw materials is calcium sulphoaluminate and dicalicium silicate.It has types of 72.5,82.5,92.5,which is determined by the early compressive strength reach in 7days.
The CSA Cement is manufactured under a strict quality systems GB/T19001-2000(ie,ISO9001:2000) and GB/T24001-1996(ie,ISO14001:1996).
Properties:
Fast setting
Rapid hardening
Low dry shrinkage
Micro expansion
Sulphate resistant
Low alkalinity
Good fluidity
ect.
Application:
With the properties it equipped with,it is particularly suit to formulators of products such as self-leveling or self-smoothing compounds,rapid hardening screeds,title adhesives,non-shrinke grouts,water stopping mortars and special mortars,ect.
It also can be combination with silicate cement,portland cement,anhydrite ect mineral products.Depending on the type of mixes and technology emplyed,CSA cement can be used to obtain and control various properties,take portland cement as anexample:
Acceleration of setting time and compressive strength and flexural at a very early age(several hours).Besides,with some type of portland cements and in formulated products containing additives which control the setting and hydration ,the long term properties is similar to those of the original Portland cement,so it is necessary to check the behaviour of each portland cement it blended with.
The characteristics of portland cement to be considered are:
C3A content
Mineral admixture type and content
Type of Calcium Sulphate used
Setting time
Rheology
