Concrete polycarboxylate superplasticizer refers to the fact that after adding it, it can reduce the water demand of concrete under the condition of maintaining basically the same fluidity, thereby improving the strength and durability of concrete, or in the condition that the amount of cement used and the water-cement ratio remain unchanged. , adding concrete fluidity, admixtures to improve concrete workability.
Lubrication effect: The polar hydrophilic groups in the water reducer are oriented and adsorbed on the surface of cement particles, and are easily associated with water molecules in the form of hydrogen bonds.
The force of this hydrogen bond association effect far exceeds the molecular attraction between water molecules and cement particles. When the cement particles absorb sufficient water reducing agent, the surface layer of the cement particles forms a stable layer of solvated water by virtue of the association effect of R-SO3θ and the hydrogen bonds in the water molecules, plus the hydrogen bond association between the water molecules.
The film plays a three-dimensional protective effect, blocks the direct contact between the cement particles, and plays a lubricating effect between the particles.
Usually the polycarboxylate superplatsicizer will be packed in drum (for liquid), and if for powder it could be packed as 25kgs/bag. As polycarboxylate superplasticizer with many different types, you may need to send us very accurate requirements or better can send us the specification for we can check for you.
Right now we mainly producing 2 types of products: Water reducing and slump retention. To import polycarboxylate superplasticizer, it’s very important to find a stable supplier with mature technology. We know that the stable and good quality is very important for longer business, for all the chemicals, we have very strict inspection before deliver out.
