Polycarboxylate Superplasticizer (High Slump Retention Type)

2019-06-14 14:02:36

Polycarboxylate Superplasticizer (High Slump Retention Type) is a new generation of slow-release polycarboxylate water reducer independently developed by the company, which can significantly inhibit concrete slump loss. The product is suitable for high-water-reducing polycarboxylate water reducer. It is used in combination or alone and has excellent performance.
Technical principle:
Under the alkaline condition of concrete, the reaction gene in the molecular structure can slowly release the dispersing gene, and continue to disperse the cement, thereby achieving the effect of inhibiting concrete fall loss.

Features:
The slump retention value is large. After 1 hour, the slump can reach more than 80% of the slump of fresh concrete, which can effectively solve the problem of rapid slump loss of concrete.
After use the product, the concrete has excellent performance and the fresh concrete has good workability, its hardening and durability being excellent.
It has wide adaptability to Portland cement, ordinary Portland cement, slag silicate, fly ash cement, pozzolan cement and various admixtures.
Be green. The raw materials used are non-toxic and harmless, and no waste is produced in the production process.

Instructions:
The usual dosage is 0.6%-1.2% (based on the total amount of cementitious materials), and the optimum dosage should be determined by experiment according to the engineering materials and characteristics;
It is suitable for the combination of high water-reducing polycarboxylic acid water reducing agent or alone.

Scope of application:
It is suitable for the preparation of early strength concrete, retarded concrete, precast concrete, cast-in-place concrete, large fluid concrete, self-compacting concrete, mass concrete, high performance concrete and fair-faced concrete, ready-mix in various industrial and civil buildings and cast-in-place concrete. It is especially suitable for low-grade commercial concrete.
It can be widely used in large-scale projects such as high-speed railway, nuclear power, water conservancy and hydropower projects, subways, large bridges, highways, harbor terminals, etc.
It is applicable to all types of workers and civilian construction and commercial concrete mixing stations.
