(2) Excessive mixing of superplasticizer will cause bubbles to occur, which will affect the growth of early concrete strength.
(3) When the amount of chloride salt admixture is large, it will reduce the chemical resistance and abrasion resistance of concrete, increase the early shrinkage of concrete, and reduce the freezing-thawing resistance and flexural strength of concrete.
(4) If the accelerator is excessively mixed, the setting time will increase instead, and the strength of the concrete will decrease more severely in the later stage.
