Type PCS-3 Rapid-setting Accelerator
for Portland Cement and Light Cement Products
Summary
● Type PCS-3 Rapid-setting Accelerator for Portland Cement, also named Rapid-setting Early-strength Admixture or Rapid-setting Additive for portland cement, is a kind of professional admixture for Portland Cement series. Type PCS-3 Rapid-setting Accelerator can effectively improve performance of portland cement , such as rapid setting, fast hardening, high early strength, etc. So it can make portland cement or concrete products get short setting time and rapid demoulding.
● Type: PCS-3
● Served Cement Kinds: Portland Cement, Ordinary Portland Cement, Compound Portland Cement, Sulfate Resistance Portland Cement
Characteristics
● Appearance: grey or dust color powder
● Rapid-setting: effectively reducing setting time of initial setting and final setting; more quantity of PCS-3 and more high temperature of mixed water, more short setting time and more fast hardening.
● High-strength and Early-strength: effectively increasing early strength of cement products, more added quantity of PCS-3 more high early strength
● Fast-hardening Demoulding: to adjust mixed quantity of type PCS-3 to suitable ratio and improving mixing water temperature like more than 40 degree C, it can get the better effect of fast demoulding within about 30 minutes to 1 hour, or more short time for cement paste.
● Type PCS-3 does not belong to flammable solids, corrosives, toxic substance, dangerous goods.
● Non-burned
● When PCS-3 is used in cement or concrete, it can take place of the same quantity of cement.
● PCS-3 is environmental friendly to surroundings, free of poisonous heavy metal contents such as chromium(Cr), plumbum(Pb), hydrargyrum(Hg), and chlorine salt composition(Cl) etc.
Application
Type PCS-3 is always used in making the following Portland cement or concrete products,
● Artware, decorative articles
● Cement Products with European style, Landscapes arts
● Wall Plate, Cement Bricks, Flowerpot
● Inner layers of Safe Deposit Box
● Foamed Concrete or Foamed Cement Board
● Other cement products and concrete building
Usage
● Recommended Added Quantity: generally, 3.0 to 10.0% of cement by weight.
The factual final added quantity must be confirmed as per performance request of mortar or concrete, and different ratio and change of mixing materials, and different production and construction condition; the test result in labs will be as the final added data.
● When batches of cement and type PCS-3 are changed, for the new and exact added quantity, the trial in Labs must be done again.
● W/C Ratio recommended: 0.25 to 0.30
● Temperature of working room and mixing water: normal temperature, recommended not less than 25℃; it is the best to improve the temperature of mixing water attaining 40℃ for getting the faster hardening time, but not more than 60℃.
● Mixing Process: first to mix type WCS in dry together with white cement and sand to even, then to add mixing water and continue to mix to even, recommended mixing time in dry and wet not less than 3 minutes.
● After demoulding, the cement products should be cured in wet.
● Blocked or wetted cement can not be allowed to use again.
Transport, Storage and Package
