Concrete pumping agent with stable performances

Abstract

A concrete pumping agent with stable performances is prepared from the following raw materials, by weight, 6-9 parts of triethanolamine, 5-7 parts of urea, 4-9 parts of bentonite, 1-4 parts of ultrafine fly ash, 6-9 parts of polyacrylamide, 4-9 parts of an acrylic copolymer, 5-10 parts of hydroxypropyl methylcellulose, 3-8 parts of re-dispersible latex powder, 5-7 parts of chrome oxide, 6-11 parts of phenyl salicylate, 4-10 parts of polyoxyethylene alcohol ether, 2-6 parts of sodium methyl silicate, 1-5 parts of triterpenoid saponin, 2-5 parts of monoethanolamine, 2-8 parts of sodium lauryl sulfate, 6-10 parts of p-hydroxy N-methylcyclohexylamine and 1-5 parts of a polycarboxylate water reducer. The concrete pumping agent with stable performances has the advantages of stable chemical properties, very good safety, low temperature resistance, strong applicability to cement, and wide range.

Description

technical field [0001] The invention relates to a concrete pumping agent with stable performance. 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] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a concrete pumping agent with stable performance, stable chemical properties, good safety, ...
