Abstract

The invention discloses a concrete pumping agent capable of preventing pipe blockage and water seepage. The concrete pumping agent is characterized in being prepared from the following components in parts by weight: 4 to 7 parts of di (2-chloroethyl) hydrophosphate/piperazine-N, N-bis (2-hydroxyethane sulfonic acid) disodium salt polycondensate, 0.2 to 0.5 part of hyperbranched polyamino acid, 10to 15 parts of maleimide-tri (ethylene glycol)-propionic acid/triethanolamine oleate soap/vinyl phosphonic acid copolymer, 2 to 4 parts of kleemanite, 0.1 to 0.3 part of carboxymethyl chitosan and 30to 40 parts of water. The invention further provides a preparation method of the concrete pumping agent capable of preventing pipe blockage and water seepage. The concrete pumping agent disclosed by the invention is good in adaptability to cement, good in pumping effect, excellent in comprehensive performance, small in mixing amount, small in negative influence on the comprehensive performance ofconcrete, stable in quality and safe and environment-friendly to use, and the concrete added with the pumping agent is good in workability, excellent in pumpability and free of a water seepage phenomenon.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a concrete pumping agent without blocking pipes and water and a preparation method thereof. Background technique [0002] With the rapid development of my country's construction industry and the acceleration of infrastructure construction, concrete is widely used in civil engineering because of its rich raw materials, low price, simple production process, high compressive strength, good durability, and wide range of strength grades. project. Concrete is one of the most important contemporary building materials. It is an artificial stone made of cementing materials, aggregates, aggregates and water prepared in a certain proportion, stirred and vibrated, and cured under certain conditions. There are often some problems in the construction process of traditional concrete. For example, in the process of concrete pumping and construction, the problem of rapid loss of concre...
