Supplier: Chemical, building materials, concrete admixture, fac polycarboxylate superplasticizer, fac-1 naphthalene-based superplasticizer, fac-2 early strength superplasticzier, fac-3 antifreezer
Buyer: MPEG-1200, Naphthalene, MAA
This super plasticizer admixture can strongly disperse cement particles and decrease the water-cement ratio and improve concrete strength of different ages. It greatly improve slump and expansion of the concrete, so that the performance of concrete is significantly improved. Basically speaking, it does not change the setting time of concrete and can significantly increase the early strength of concrete. It is of chlorine-free and low-alkali and no rust on the steel and also can effectively prevent the alkali-aggregate reaction of concrete. Liquid: 200Kg, Barrel Powder: 25Kg, Inner Lined Woven Bags
It is suitable to be used in the environment of over -5. It can greatly improve the early strength of concrete and has good adaptability to the cement. It is of multifunction such as water-reducing, plastic and improving the workability of concrete. There is no harmful materials contained in this product that decrease the strength of later stage and destroy the inner construction of the concrete. It is of free ammonia and chlorine and no corrosion to the steel. 25Kg,Bags
It is suitable for all kinds of concrete that needed to be constructed under the degree of -5 to -15.It has the features of antifreezing, early strengthening, water reducing, plastic securing and so on. There is less loss in slump, good adaptability to a variety of cement and mixed materials. It is of chlorine-free and low-alkali, non-ammonia type and without harmful substances, no rust on the steel, and considered as a environmentally friendly products. 25Kg, Bags
This product can significantly improve the plasticity and workability of concrete. It can significantly reduce concrete segregation and bleeding and improve freeze-thaw resistance, impermeability and other indicators of durability. It is evenly made up of by small bubbles that distributed evenly and enclosed with each other and is regarded as the regulator of air volume which is stable. 25Kg, Bags
