Polycarboxylic acid superplasticizers are used as high range superplasticizers in high performance concrete.Water content:3.6%pH:8Total alkali:5.8%Gas content:3.1%…
Adding high-efficient water reducing agent is the most direct and effective means to adjust and optimize the ratio of concrete and improve and strengthen the properties of concrete, which can meet the requirements of most concrete construction at pre…
Efficient polycarboxylic acid Superplasticizers transform the hard and low slump concrete into flowing, toppable and easy-to-place. They improve machinability, speed up surface treatment, increase strength, save cement and help reduce shrinkage and t…
There are several kinds of water reducers: lignosulfonate, naphthalene sulfonate water reducing agent, polycarboxylate-based high-performance water reducing agent.…
Polycarboxylic acid superplasticizer has been widely used in many construction fields. Modern concrete has high requirements for additional functional additives, so polycarboxylic acid water-reducing agent in the concrete system, it should consider…
Concrete superplasticizer is high efficienct water reducing agent. Its difference from ordinary water reducing agent lies in the high-water reduction rate. The water reduction rate of ordinary water reducing agent is generally 5%-10%, and the water r…
