Polycarboxylate superplasticizer is a kind of liquor as the molecular structure of the graft copolymer containing carboxyl surface active agent, which belongs to the third generation of superplasticizer liquor, period of excellent comprehensive performance, is an ideal additive to produce concrete with different strength grades and components, especially suitable for the configuration of pumping concrete, high strength concrete, concrete, self compacting concrete and the concrete component.
1, low dosage, high water reducing rate: water reducing rate can be as high as 45%, can be used to prepare high strength and high performance concrete.
2, when the slump is light, the loss is small: the slump loss of premixed concrete 2H is less than 15%, which is very favorable for long distance transportation and pumping construction of ready mixed concrete.
3, concrete work is good: PC polycarboxylates high-performance Jianshuiji concrete even in high slump circumstances, also won't have obvious segregation, secrete water phenomenon, concrete appearance color uniformity. It is very beneficial to the preparation of high fluidity concrete, self leveling concrete, self compacting concrete and fair faced concrete. When used for preparing high grade concrete, the workability of concrete is good, the cohesiveness is good, and the concrete is easy to stir..
4, small shrinkage of concrete: can significantly reduce the shrinkage of concrete, significantly improve the volume stability and durability of concrete.
5, very low content of alkali alkali content is less than 0.2%.
6, good product stability: no precipitation at low temperature.
7, the product green environmental protection: product non-toxic harmless, is green environmental protection product, is advantageous to the sustainable development.
8, good economic benefit: engineering comprehensive cost less than using other types of products.
