I. Introduction

This product is a non- air-entraining type efficient concrete water reducer with β-naphthalene sulfonate-formaldehyde polycondensate as a main component, features no delayed coagulation and good compactibility, can reduce water cement ratio and greatly improve the early and long-term strength of concrete and can be used to prepare high-flow, high-strength, high anti-permeable and high-performance concrete and premixed concrete. This product is in line with the standards of GB8076-2008 and GB18588-2001.

Ⅱ. Product performance

1. The product has a significantly water dispersion reducing effect with the water-reducing rate reaching 18-28% and can improve the liquidity of the cement neat paste and concrete mixture in the case of low water-cement ratio.

2. In the case of maintaining the same water-cement ratio, it can greatly improve the workability of concrete, improve the liquidity as well as bleeding separation, improve the bond stress of reinforced concrete and make the concrete surface smooth.
