Superplasticizer used in concrete refers to the fact that after mixing, it can reduce the water demand of concrete under the condition of maintaining basically the same fluidity, thereby improving the strength and durability of concrete, or under the…
Polycarboxylate superplasticizer has high surface activity and good foam retention, which will affect the strength of concrete due to excessive gas content.…
Concrete water reducing agent is one of the technical ways to reduce the cement dosage, improve the utilization rate of industrial waste residue, and realize the durability and high performance 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…
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…
In the coming weeks, problems with chip production due to a global shortage of neon could start to manifest. Zeno pointed out that if inventories are depleted by April, and chipmakers have no sources in the re…
According to the United Nations website, in the past week, countries reported an 8% increase in new crown cases to the WHO, with more than 11 million positive tests. Tedros noted that although some countries hav…
