Abstract

An improved concrete pumping agent is prepared from the following raw materials in parts by weight: 6-10 parts of aluminium sesquioxide, 3-9 parts of calcium lignosulphonate, 5-11 parts of hydroxypropyl starch ether, 5-8 parts of methyl cellulose, 2-7 parts of ammonium carbonate, 2-5 parts of an amine cosolvent, 6-9 parts of sodium alkylbenzenesulfonate, 7-11 parts of perfluorooctyl triethoxysilane, 2-4 parts of sulfur trioxide, 4-10 parts of nano silica, 4-10 parts of sodium trimethyl silanol, 1-5 parts of p-hydroxy N,N-dimethylcyclohexylamine, 3-8 parts of diethanol amine, 40 parts of water and 5-8 parts of silica powder. The improved concrete pumping agent has the benefits of being stable in performance, high in temperature applicability, wide in application range, and high in water reducing rate.

Description

technical field [0001] The present invention relates to an improved concrete pumping agent. Background technique [0002] As we all know, the pumping concrete must be wetted and lubricated before pumping, so as to reduce the frictional resistance through the pipeline when the concrete is pumped, and ensure the smooth progress of the pumping. Concrete pumping agent can greatly improve the fluidity of the mixture, and can maintain the fluidity of the mixture for a long time, and can keep the concrete in good workability after being conveyed under pressure without segregation or bleeding. The water-reducing properties of the pumping agents on the market are average, and the construction is difficult, which wastes resources. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide an improved concrete pumping agent with stable performance, good temperature applicability, wide a...
