As we all know, polycarboxylic acid water reducing agent is a new type of water reducing agent.
It has been applied in practical engineering since the late 1990s. In recent years, it has been used in some large projects, and its excellent performance has been recognized by many people in the industry.
As we all know, for some traditional water reducing agents, sometimes there will be a variety of problems in the process of use, such as poor working performance, easy to appear bleeding phenomenon, not smooth and so on,
and polycarboxylic acid water reducing agent is not, its advantages are mainly reflected in the following aspects:
1, low content, high water reduction rate;
2, in use, can make concrete has a good plastic protection effect, and will not prolong the setting time of concrete, which is the shortcomings of naphthalene series water reducer can not be overcome;
3. Concrete mixed with polycarboxylic acid water-reducing agent has better water retention, and the aggregate in concrete can maintain a good suspension state after vibration, without bleeding, bleeding and stratification;
4, polycarboxylic acid superplasticizer strong water reduction, so that the concrete preparation will not appear bleeding, segregation phenomenon, good working performance.
It can be seen that polycarboxylic acid water reducing agent has the advantages that other water reducing agents do not have, is a very ideal choice of water reducing agent, can effectively ensure the performance of concrete.
