Early strength polycarboxylic acid water reducer

Polycarboxylate Superplasticizer:

PCE is a new generation of high-performance water-reducer in cementwhile PCE is a comb-type polymer,which is usually prepared by grafting long side chain with a polyoxyethylene(PEO)groupcan disperses in cement uniformly without aggregation which is different significantly from the conventional PCE.

Appication

Polycarboxylate Superplasticizer(PCE) is a kind of superplasticizeris mainly used in cement concrete.In chemistry,Poly-carboxylate-based is an organic and polymerio electrolyte.As polymer surfactantapplied in other paste materials such as gypsum products and ceramic products to reduce water content.

Poly-carboxylate is a weak electrolyte.It can only be fully dissolved in an alkaline solution. It can compound with cations in cement/water system to control the cement hydration process and thus to reduce the slump loss of the concretePoly-carboxy ate achieves its water reducing effect through the yield of electrostatic repulsion and steric hindrance

when it is absorbed to the cement particles.HencePoly-carboxylate is the most effective superplasticizer for cement concrete.

Incompatibility with PNS superplasticizers:Use of PCEs and PNS-based products in the same concrete mixture results in rapid loss of workability.Thusthe two technologies PNS and PCE. should not be used in the same concrete mixture.

Poly-carboxylate is a raw material for superplasticizer.It is recommended that applicants should determine the Poly-carboxylate dosage in their own formulation according to their trial runs.

Product characteristics

1.High water reduction rate: at low content, it has a high water reduction efficiency, giving the material system excellent fluidity, effectively improving the compactness and strength of the system, and the highest water reduction rate can reach 40%.

2.High dispersion: It has excellent dispersion ability, can quickly adsorb, reduce mixing time, give the material system excellent workability and constructability, improve construction efficiency and meet different construction requirements.

3.High adaptability: It has excellent adaptability with various cement-based systems, and is well compatible with other functional admixtures, and does not reduce application performance under various conditions.

4.Early strength and high strength: It has excellent early strength and enhancement effect, and the enhancement effect is significant under the same conditions, and the dosage can be reduced under the same demand.

5.High durability: enhance the compactness of the hardened slurry, improve the shrinkage and creep performance, reduce cracks, enhance the permeability resistance, corrosion resistance and chloride ion penetration resistance, and improve durability.

Green environmental protection: does not contain harmful substances, belongs to environmentally friendly materials
