Description

1. Technical field

[0001] The invention relates to an admixture for cement concrete, especially a high-efficiency concrete admixture. 2. Background technology

[0002] In order to improve the performance of cement concrete, admixtures or admixtures are often added to the cement concrete. The admixtures or admixtures currently sold in the market are single-function and can only solve a certain performance problem of cement concrete. For example, NNO water reducing agent can only reduce water; early strength agent can only achieve early strength. Effect; the retarder can only play a retarding effect, but for cement concrete, there are many properties that need to be solved. This single effect cannot fully solve the performance problem of cement concrete. At the same time, it is a powdery product, which is not easy to mix well; in the maintenance of cement concrete, it needs to be covered with thermal insulation materials, which brings inconvenience to maintenance. The disadv...
