Sulfate Resistant Cement CSA Cement


General characteristics:


CSA cement  is a hydraulic binder based on calcium sulphoaluminate, rather than calcium aluminates which are the basis of CALCIUM ALUMINATE CEMENT or calcium silicates which are the basis of PORTLAND CEMENT. The difference gives CSA BINDER properties particularly suited to formulators of products such as self-leveling or self-smoothing compounds, rapid hardening screeds, tile adhesives, non-shrink grouts, rapid setting and special mortars.


CSA cement is used in formulated products either as a hydraulic binder by itself or with the addition of calcium sulphates, or in combination with PORTLAND cement. The setting time is quicker than that of PORTLAND cement, and it also has a rapid strength development. CSA BINDER does not release free lime during hydration thus eliminates the major cause of efflorescence.


CSA cement is manufactured under a strict quality assurance systems GB/T 19001-2000 (i.e. ISO9001:2000) and GB/T 24001-1996 (i.e. ISO 14001:1996)) which accommodates the technical requirements of building chemistry formulators.


The properties of CSA cement conform to the standards of the manufacturer and to the

Chinese relevant standards.

Reactivity with Portland cement


CSA cement may be used in combination with other mineral products, for example

PORTLAND cement, calcium sulphates and fillers, or with organics such as polymers in latex form or in redispersible form.


Depending on the type of mixes and technology employed, CSA cement can be used to obtain and control various properties.


The behaviour of PORTLAND cement is vary variable. In general, acceleration of set increases progressly with the addition of CSA cement. The amount of CSA cement needed to obtain a specific setting time varies considerably depending on the origin of the PORTLAND cement and performance can be modified with the use of additives.


The strength development of CSA cement/PORTLAND cement and/or Calcium Sulphates depend on the nature of the PORTLAND cement and/or Calcium Sulphates used. In general these mixes will develop mechanical strength at a very early stage (several hours). 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, however it is necessary to check the behaviour of each PORTLAND cement used.


The characteristics of PORTLAND cement to be considered are:


C3A content

Mineral admixture type and content

Type of Calcium Sulphate used


Additives will also influence the properties of these mixes:

Setting time


Mechanical performance


These properties are applied to obtain a wide range of products:

Fast setting cements

Rapid hardening mortars

Tile adhesives

Self-leveling compounds

Non-shrink grouts

Water stopping mortars



With a careful selection of the constituents (OPC, calcium sulphates, additives), it is possible to create mixes with a range of different hydraulic properties:


Adjustable setting time

Rheology adapted to the application

High early strength

High long term strength

Shrinkage compensation


Use of Additives


CSA cement may be used in combination with chemical additives such as:

polymers, either in latex form or redispersible powder form





rheology modifiers



Package and Store


 CSA cement is normally supplied in one-tonne bag which include a moister resistant barrier. However, in common with all hydraulic binders CSA cement must be kept from moisture, and can retain its properties for up to six months when properly stored.
