superplasticizer--sodium naphthalene formaldehyde

superplasticizer--sodium naphthalene formaldehyde low water/cement ratio low dosage of 0.5% high slump flowable concrete

superplasticizer--sodium naphthalene formaldehyde

1.Description:

It is a high efficient concrete admixture. The raw material is sodium naphthalene formaldehyde. It has all the traditional characteristics of concrete admixture,high water reducing effect, non-air-entrained, low Cl ion content and good compatibility with various cements. When this product is applied, the early strength and the anti-water-permeation of the concrete are increased obviously, also the construction property, the water-keeping ability of the concrete and the steam curing adaptation will be better. the pwder particle structure of this water reducer is improved by a special powder spraying dry technology. So the fluidity of its powder is very good. When it is used in the powder building materials, the mixing effect is very ideal. It's not only suitable for the pump concrete, the prefabricated concrete, the tube pile concrete,the fair-faced concrete,the decoration concrete,the self-flowing concrete, but also suitable for the dry mixing mortar, the gypsum powder, and all the other pwder materials. This product is complied with GB8076-1997.
