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 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 HCSA BINDER conform to the standards of the manufacturer and to the

Chinese relevant standards.

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
