How to cause portland cement products rapid demoulding ? What if you want the result of fast demoulding of Portland cement or concrete products? To recommend type PCS-3 Rapid-setting Accelerator made by Shenzhen Chenggong Building Materials Co., Ltd.   Type PCS-3 Rapid-setting Accelerators, also named Fast-hardening Accelerator or Rapid-setting Admixture, is specially suitable for making cement artwares, cement structure members, precast element, ordinary wall plates, light weight cement boards, foaming cement boards or foaming concrete products, cement bricks made of portland cements. It is able to cause these cement or concrete products rapid setting, fast hardening and fast demould, then greatly increase work efficiency of mould.   And when choosing Rapid-setting Accelerator, except need to consider the actor of rapid-setting, it is very necessary to notice if the additive may bring bad influence to late strength of cement products. But type PCS-3 Rapid-setting Accelerator won’t reduce the final strength of cement or concrete products, and even will improve their final strength.       [ Print ]  [ Back ]

Type WCS Rapid-setting Accelerator for White Portland Cement Type WCS Rapid-setting Accelerator, including type WCS-1 and WCS-2, is a kind of professional admixture special for white portland cement. It is also named Early-strength Admixture, Fast-hardening Admixture or Rapid-setting Additive for white cement. Just like grey portland cement, white portland cement (also simply named white cement) always has slower setting and lower early strength. Type WCS Rapid-setting Accelerators can cause white cement mortar, cement products or concrete products, paint of white cement, etc., rapid setting, fast hardening and high early strength. So it can help white cement products to get the effect of shorter setting time and rapider demould. And after using type WCS Rapid-setting Accelerator, the late strength of white cement products will not fall and even can get improvements in a way. And it 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.

Type PCS Rapid-setting Accelerator for Portland cement and Foaming cement and Concrete Type PCS Rapid-setting Accelerator, including type PCS-2 and PCS-3, is a kind of professional admixture special for grey Portland Cement. It is also named Early-strength Admixture, Fast-hardening Admixture or Rapid-setting Additive for grey portland cement. Grey Portland cement always has slower setting and lower early strength. Most of producers of cement and concrete products are puzzled by these questions all along. Type PCS Rapid-setting Accelerators can cause grey portland cement mortar, cement and concrete products, light weight cement cement or concrete boards, foaming cement boards and foaming concrete products rapid setting, fast hardening, high early strength. So it can help grey portland cement products and light foaming cement and concrete products to get shorter setting time and rapider demould effect. Moreover, after using type PCS Rapid-setting Accelerator, the late strength of cement products will not fall and even can get improvements in a way. And it 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. Because of these fine characters, our type PCS Rapid-setting Accelerators are better than the similar rapid-setting additives in the market.

CSA Binder is a kind of special building materials. One of its basic performances is that it has high early strength. It is the main composition of rapid-setting cement, expansion cement, self-stressing cement. It is also used as accelerating admixture, rapid setting admixture and expansion admixture of port- land cement when construction. Our CSA Binder includes many types or grades.

Because of special performances and application, these cements are generally named special cements. They include Sulfate Resistance Portland Cement(SRC), High-strength Rapid-setting Calcium Sulfoaluminate Cement(CSA Cement), Calcium Aluminate Cement( also named High Alumina Cement or Refractory Cement), White Portland cement(also named White Cement), Low-Heat Portland Cement (also named Belate Cement), High-strength Fast-hardening Plugging Cement, etc. Just because of particularities of their performances and uses, they are always used in making many special products, project or construction, etc. Main items include type PCS-2 & 3 Rapid-setting Accelerator for Portland cement, type SAC-1 Rapid-setting Accelerator for calcium culfoaluminate cement and high alumina cement, type WCS-1 & 2 Rapid-setting Accelerator for white portland cement, Rapid-setting Accelerator for foaming cement boards and concrete products, Retarder for cement and concrete, Water-reducing Reinforcing Admixture, Expansion Additive, etc. These additives can effectively improve the performances of cement and concrete, and help to get the idea products on the different working and production conditions. They all do not have chlorine salt composition (Cl). It will not appearance to damage the cement or concrete products because of using these additive. For example, most of Rapid-setting Accelerator can cause the cement or concrete quick setting but it also will cause the late strength of cement or concrete products fall, but our Rapid-setting Accelerator will not make these problems. Our product items include Water-reducing Reinforcing Admixture and Retarder for gypsum. Type WRA-I Water-reducing Reinforcing Admixture is a kind of pure white powder, and it can cause several gypsums and gypsum products good fluidity and improve strength. Retarder can make gypsum products effectively delaying setting but its strength is almost not fallen. Alkali-resistant Glassfibre is a major materials used in Glassfibre Refinforced Concrete (GRC), made of 100% inorganic material. It is an ideal sunstitute for steel and asbestos in non-structural pre-cast concrete elements. It has good alkali-resistance performance, which enables it to resist the corrosion of high-alkali substance in cement. The characteristics of GRC include high bond strength, high elastic modulus, high impact, tensile and bending strength, fire and freezing resistant, crack resistant and excellent impermeability. It is easily formed and malleable to any designs. Overall, it is a high performance and environmentally friendly materials that can be widely used in building. Out product items include Chopped Strand, Spray Roving, Water Dispersed Chopped Strand, Scrim and Mat, etc. This item includes two acid-resistancing products, Acid Resistance Bricks and Acid Resistance Binder. As special building products, Acid Resistance Bricks are widely used in acid resistance construction and projects such as corrosion-resisting liner of Petroleum, Chemical industry, Chemical Fertilizer, Food, chemical fiber, laboratory, pharmacy, making-paper, generate electricity, smelt, electroplating room, and the inner corrosion-resisting lining of tower, pool, pot, tank, ground surface of working-room, pickling tub of electroplating factory, etc. Brick is also used for sewage conduit and open-air floor. Acid Resistance Binder is mainly used in acid proof projects for affixing Acid Proof Bricks/Tiles and as joint sealing materials of Acid Proof Bricks, also for making acid proof concrete, etc. It also can resistance high temperature. Castable Refractories belongs to non-shape refractory materials. It includes many kinds of dense castable refractories made of fireclay and high alumina raw materials. These castable refractories are mainly used in the inner linings of pyroprocessing plants for example industry furnaces. As high alumina castable refractories, they are often used in high temperature projects, for example incinerator, heat kiln in the rolling mill, kiln in glass industry, etc. It includes Clay Bonded Refractory Castables, Cement Bonded Refractory Castables, Low Cement Bonded Refractory Castables and Phosphate-bonded Refractory Castables.
