1.Product introduction

High early strength type Polycarboxylate superplasticizer is a comb-structured polycarboxylate superplasticizer that is copolymerized with carboxylic acid and ester macromonomers. The early strength of concrete mixed with this product can be significantly improved, and the later strength does not shrink. It is suitable for precast concrete and various high-strength and high-performance concrete, which can shorten the demoulding time and improve the mold turnover efficiency. This product has the following characteristics:

(1) High water reduction rate, good dispersion and dispersion retention effect on cement;
(2) The early strength enhancement effect of concrete is obvious, and the later strength has no shrinkage;
(3) The air content is low, which reduces the adverse effect of air bubbles in the concrete on the internal structure, and can improve the appearance of the concrete at the same time;
(4)Good adaptability to various grades and different manufacturers of cement, and good compatibility with admixtures.

2. Product Features

(1) High water-reducing rate: This product has a dosage of 0.15-0.3% (in terms of solid content) and a water-reducing rate of 18-40%, which can meet the needs of ultra-low water-cement ratio and high fluidity concrete. Save 10 to 20% of cement.
(2) Low slump loss: This product introduces long side chains of macromolecules in the synthesis process, on the one hand, it inhibits hydration, and on the other hand provides steric hindrance, which can keep the slurry plastic for a long time, and has good performance. slump retention.
(3) Excellent workability: The concrete prepared with this product has good workability, no segregation, no delamination, good cohesion, and is suitable for long-distance transportation and pumping.
(4) High durability: This product is polymerized by free radical aqueous solution, with very little chloride ion content, only a small amount of alkali is used for neutralization, the alkali content is extremely low, the alkali content and chloride ion content are relatively stable, and the low chlorine and low alkali can be large. Significantly improve the durability of concrete.
(5) Low shrinkage and anti-cracking: This product can reduce the heat of hydration, delay the exothermic peak, and is suitable for large-volume concrete, which can effectively reduce the cracking of concrete caused by the temperature difference of hydration.
(6) Green environmental protection: This product is polymerized with free radical aqueous solution. The raw materials do not contain formaldehyde and other pollutants. There is no sewage and wastewater discharge during the synthesis process, and the environmental load is ultra-low. It is a new type of green and environmentally friendly building materials.
as one type of high efficient water reducing admixtures,
