General characteristics

HCSA BINDER 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 HCSA 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.
HCSA BINDER 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. HCSA BINDER does not release free lime during hydration thus eliminates the major cause of efflorescence.
HCSA BINDER is manufactured under a strict quality assurance systems GB/T*********0 (i.e.ISO***1:***0) and GB/T *********6 (i.e. ISO ****1:***6)) which accommodates the technical requirements of building chemistry formulators.
HCSA BINDER is normally supplied in one-tonne bag which include a moister resistant barrier. However, in common with all hydraulic binders HCSA BINDER must be kept from moisture, and can retain its properties for up to six months when properly stored.
The properties of HCSA BINDER conform to the standards of the manufacturer and to the
Chinese relevant standards.

Reactivity with Portland cement

HCSA BINDER 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, HCSA BINDER 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 HCSA BINDER. The amount of HCSA BINDER 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 HCSA BINDER/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
Rheology
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
etc.

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

HCSA BINDER may be used in combination with chemical additives such as:

polymers, either in latex form or redispersible powder form
defoamers
retarders
accelerators
plasticizers/superplasticizers
rheology modifiers
fibers
