| description | The invention discloses a quick-acting restoring agent for preventing slump loss of pump concrete. The quick-acting restoring agent is characterized by being prepared from the following raw materials in percentage by weight as follows: 95%-99% of a polycarboxylic acid type superplasticizer, 1%-5% of a sugar-calcium retarding admixture, 0-0.1% of an air entraining agent and 0-0.1% of a defoamer. Under the condition that the pump concrete fails to meet the requirement of the in-pump slump, the restoring agent accounting for 0.07%-0.148% of the weight of a cementing material in the pump concrete is mixed in the pump concrete, the mixture is evenly mixed and then put into use, the pump concrete can be restored rapidly to meet the requirement of the in-pump slump, and the compressive strength of the pump concrete can be prevented from being reduced, accordingly, technical problems of the current pump concrete in application are effectively solved, the quality of the pump concrete is guaranteed, and good economic b |
