Admixtures that can greatly reduce the amount of mixing water under the condition that the slump of concrete is basically the same are called superplasticizers.…
Concrete superplasticizer is one of the concrete admixtures which is used most frequently. It can increase the plasticity of concrete and change the strength of concrete.…
Concrete is an indispensable raw material in the construction of construction projects. In the process of preparing concrete, in order to improve the performance of concrete, it is necessary to add water reducing agent after adding water, stone, sand…
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%…
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.…
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…
The efficient concrete admixture superplasticizer is a synthetic polymer used in the preparation of high strength concrete. They are also known as high range water reducers because their use in wet concrete can reduce the water content in wet concret…
The working principle of efficient concrete admixture superplasticizer (1) Dispersion: After the cement is mixed with water, due to the hydration of the cement particles, the cement particles form an electric double-layer structure, which makes it fo…
