Light color CSA binder

Light color CSA binder


General characteristics

Light color CSA binder with grade 82.5Mpa, is a hydraulic binder based on calcium sulfo aluminate, specially designed to be blended with anhydrite and some other materials, such as sand, crashed stone, pigments to make artificial stone & countertops by Polar Bear plant in year 2000.
This binder is manufactured under a strict quality assurance systems GB/T 19001-2000(i.e. ISO9001:2000) and GB/T 240001-1996(i.e. ISO 14001:1996) which accommodates the technical requirements of building chemistry formulators.

Application area
Advantages by using LIGHT COLOR CSA BINDER:

1.    The color of this CSA BINDER is more lighter than other cement, can be easily colored by pigment.
2.    Hydrated products have hydration alumina gel and ettringite crystals which can generate beautiful luster on surface of the artificial stone.
3.    Hydrated products of CSA BINDER are hydration alumina gel, ettringite crystals and hydrated calcium silicate, can avoid the strength decreasing.
4.    CSA BINDER is a low alkali cement, can avoid the re-alkali.
5.    Hydrated products ettringite crystals, is an expansive crystalline substance which is formed very stable over time, can avoid the cracking and shrinkage.
6.    CSA BINDER is also a low CO2Emissions cement.
7.    Rheology Adapted to the Application
8.    Sulphate Resistance,etc.

Use of Additives
Light color CSA binder may be used in combination with chemical additives such as:
The following additives might be used in combination with LIGHT COLOR CSA BINDER when making artificial marbles and counter tops.
-  Dispersible polymer powders
-  Cellulose class thickening agent
-  Retarder
-  Accelerators
-  Plasticizers/superplasticizers
-  Pigments

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

CSA cement ( CSA binder )

Introduction General characteristics CSA Cement, also named Calcium Sulpho Aluminate Cement with grade: 42.5, 52.5, 62.5, 72.5, 82.5, 92.5, is a hydraulic binder based on calcium sulpho aluminate, rather than calcium aluminates which are the basis of Calcium Aluminates Cement or calcium silicates which are the basis of Portland Cement. It can be used on its own (with a Lithium accelerator), or with an Anhydrite, Portland cement mix, Metakaolin or a combination of all. CSA Cement has the benefit of being readily adaptable to suit many different applications where both rapid set and / or high early strength gain are required. It yields controlled set, enhanced early strengths, shrinkage compensation or expansion and sulphate resistance. Uses include any cement-based product in need of these properties. CSA Cement products exhibit a range of properties to suit a wide spectrum of cement-based applications, like fast setting cements, self-leveling or self-smoothing compounds, sel...

CSA cement ( Rapid set cement )

CSA cement is one type of cement has the advantages of super high early and final strength, low alkaline, fast setting time, rapid hardening, frost & corrosion resistance, etc. Due to its wonderful performance, it can be used in many applications like mining industry, bridge decks, airport runways, patching concrete roadways, sidewalks, pavements, etc. where rapid strength developments are necessary. CSA cements offer tremendous advantages over Portland cement in terms of strength, setting time, speed and greeness .It main features are high initial and final strength, concentrative hydrating heat release, fast setting time, good fluidity, high frost and corrosion resistance, impermeability, low carbon, etc. It can be used in the following areas: 1. High strength cement & concrete 2. Dry mortars, such as tile adhesive, high strength grouting materials, self-leveling materials, rapid setting mortars, etc. 3. Concrete repair materials, Pavement repairs and other repair...
