Fast setting cement

CSA cements are in great performance in super high strength,very early strength,fast setting time,low alkali,rapid hardening,etc

The fast Setting Cement is named by its main character of fast setting time. Its commodity name is Calcium Sulfo-aluminate cement (CSA cement). Its main minerals are anhydrous C4A3S, C2S,that is a kind of blended hydraulic cement and used in concrete repair, which is requiring the highest durability and fastest strength gain. Its main character is fast setting, rapid hardening, high early compression strength, low alkali, high frost resistance, high corrosion resistance, low shrinkage, low permeability, superior durability and with shorter curing time. Fast Setting Cements, achieve compressive strengths of in excess of 30MPa in just 24 hours, compared with 28 days for regular Portland cements. This allows precast prdoucts makers to create much stronger concrete much faster. Fast Setting Cements are also more environmentally friendly than Portland cement, producing 62% less carbon dioxide during their manufacture. CSA cement can be used as a simple 100% replacement for the Portland cement in a concrete formula, making it a simple and easy way to produce greener concrete.Fast Setting Cement Main ApplicationsDue to the fast setting, high early strength, shorter curing time, low alkali and greener characters, fast setting cements are widely used as the raw materials to produce custom precast products where mould removal could start within one hour after finishing. Concrete units are then immediately ready for next handling, processing, and shipping without delay. Steel inserts are safely used in fast setting cements. Fast Setting Cement in uses of precast products for residential and commercial construction, such as to produce columns, balustrades, door surrounds, sills, jams , retaining walls and concrete coutertops. Fast Setting Cement for producing GRC(GFRC) wall panels. Fast Setting Cement Techinical Data Sheet1.Specific surface area (M2/kg) ≥4002.Setting time(min) Initial setting time≥25; Final setting time≤180 (The setting time can be adjusted according to client’s request) 3.Alkalinity: In cement slurry of water cement ratio 1:10, one hour’s PH value≤10.5 4.Free expansive rate: 1:0.5 cement sand ratio. The free expansive rate of 28 days is 0.00%~0.15%;

Fast Setting Cement Package

Fast Setting Cement is available in 25kgs bags, 50 kgs bags and 1 ton-jumbo bag.

Notice in using Fast Setting Cement Fast Setting cement is similar to Portland cement in color and most mixing and use procedures.When fast setting cement is used in any temperature different than the normal 20°C(70°F), special attention should be made to the setting time limitations and requirements.Field test should be made to fine-tune the water/cement ratio and the retarder percentage to be used to reflect the temperature, humidity and job conditions.Calculated amount of retarder should be mixed with water prior to concrete mixing.
