Polycarboxylate Superplasticizer Powder high water reduction rate,
good dispersion,
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.
.Main performance characteristics
1. High water reduction rate, excellent dispersion, up to more than
40% water reduction rate when saturated content.
2. Good early strength and enhancement effect, high early strength
growth rate, improve shrinkage performance and reduce the
carbonization rate of concrete.
3. Greatly improve the durability of concrete, can improve initial
strength and finial strength of concrete, improve water repellent
and anti-freezing, reduce the shrinkage and the carbonization rate
of concrete, alkali - resistant aggregate reaction, improve
durability.
4. Good adaptability, all kinds of Portland cement, ordinary
Portland cement, slag Portland cement and all kinds of admixture
have good dispersion.
5. Good slump retention performance, with good extension of the
concrete transport time and site detention time, to ensure the
concrete pumping construction performance.
Recommended parameters and usage
1. The general admixture amount of WJF09 polycarboxylate
superplasticizer is 0.3% ~0.6% of the total weight of cementing
materials, and the specific admixture amount should be determined
through experiments by test.
2. This product can be added to sand, stone, cement and admixture
at the same time or later with mixing water until the specified
time.
3. In order to achieve good water reduction effect, the recommended
mixing time is not less than 120s by concrete mixing machine.
