CSA BINDER

Product Details:

Introduction:
Calcium Sulfoaluminate Binder is a pure CSA clinker and also known as CSA Binder grinded without any additives (Gypsum etc….), and is a hydraulic cementitious mineral blend high in C4A3S (Calcium Sulfoaluminate Crystals).

CSA Binder is used in formulated products either as a hydraulic binder by itself or with the addition of calcium sulphate 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 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.

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

The properties of CSA Binder conform to the standards of the manufacturer and to the Chinese relevant standards.

CSA binder reactivity with Portland cement

CSA 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 foam or in redispersiblefoam.

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

The behavior of Portland cement is variable. In general, acceleration of set increases progressively with the addition of CSA Binder. The amount of CSA 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 CSA 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 behavior of each Portland cement used.

CSA binder Application

• Concretes repair (for example bridges, airport runaways and parking apron, etc.)
• Technical Rapid-Setting Mortars (for example restoration and repairs, etc.)
• Self-Leveling Floor Screeds
• Sprayed Concretes and Shotcretes
• Mining Products, for example: mining roof suuport materials.
• Plasters & Mortars (i.e. Joints, Sulfate Resistance, No-Shrinkage, etc.)
• Special adhesives
• Concrete Precast Products
• Glass fiber reinforced concrete (G.R.C.) 

CSA binder packing and shelf life:
