High performance polycarboxylate Super plasticizer with high slump retention and water reduction
------XRT-SC
Polycarboxylate Super plasticizer Introduction
XRT-SC Polycarboxylate superplasticizer is made of modified alkylene polyoxyethylene ether monomer, also known as six-carbon monomer. Widely used in the synthesis of high water reducing properties of XRT-SC is a new generation of modified polycarboxylic acid superplasticizer polyether independently developed and synthesized, through free radical polymerization with substances containing double bonds (such as acrylic acid, maleic anhydride, etc.) to produce Polycarboxylate superplasticizer.
The polycarboxylate superplasticizer synthesized from 6-carbon monomer has good particle dispersion and excellent slump retention performance, good adaptability and durability, and green environmental protection.
1.High water reduction rate: concrete water reduction rate of more
than 40%.
2.Easy to control production: by adjusting the molecular weight of
the main chain, the length and density of the side chain, and the
type of the side chain group, the water reduction rate, plasticity and gas zone are controlled.
3.Good ability to maintain slump. Delay concrete transport time and construction site retention time, guaranteed
Pumpability of concrete.
4.Good adhesion: the concrete has excellent workability, no stratification, no segregation, no water seepage.
5.Good dispersion: the concrete fluidity is large, and the self-compacting concrete is easy to deposit and compact.
6.High strength increase rate: greatly improve the early and late strength, reduce energy loss. Reduce cracking,
shrinkage and creep.
7.Wide adaptability: compatible with ordinary Portland cement, Portland cement, slag Portland cement and all kinds of cement
Blends with excellent dispersion and plasticity.
8.Good strength and durability: low porosity, low alkali and chloride ion content. Improve concrete strength and
durability.
9.Environmental products: No pollution in the production process.
