High range water reducer is the key material and essential technical means for preparing advanced cement-based materials. The use of superplasticizer can produce ultra-high-strength concrete with a compressive strength of 120-150MPa, which is far higher than the strength level of cement, which ensuring concrete has good construction performance.

At present, the synthesis process of the naphthalene-based water-reducing agent (SNF) is relatively mature, the price is relatively low, and the compound performance with various admixtures is good. So far, it is still widely used in the preparation of various ready-mixed concrete and precast concrete.
