YT-203 retarding polycarboxylic acid high performance water reducing agent

 

Product Overview

YT-203 retarding polycarboxylic acid high-performance water reducing agent is a new generation of environmentally-friendly and synergistic polycarboxylate superplasticizer developed by our company in combination with the current increasing concrete construction technology, climatic conditions and cement varieties.It is mainly composed of a water reducing agent and other functional admixtures.

 

Polycarboxylic acid high performance water reducing agent (2)Product main performance

The products mainly implement the GB8076-2008 "concrete admixture" standard and the Ministry of Railways TB10424-2010 "railway concrete engineering construction quality acceptance criteria", all performances meet the above standard requirements.

1. The water reduction rate is high, which can save more than 15% of cement. Especially under the same mix ratio, each cubic meter concrete can save 15-30 kg of cement.

2. Effectively adjust the setting time and lead to initial retardation effect. Which can meet the long-distance transportation requirements of commercial concrete since its little slump loss over time.

3.Workability, water retention, cohesiveness is greatly improved, no stratification, segregation and bleeding.

4.Can reduce the early hydration heat release rate of concrete, is conducive to the pouring of large volume concrete.

5.Significantly improve the compressive strength, flexural strength, tensile strength, impermeability and durability of concrete .
