Abstract

Belonging to the building material manufacturing field, the invention discloses a concrete pumping agent and a preparation method thereof. The concrete pumping agent consists of the following raw materials by weight: h 20-30 parts of ydroxyethyl methyl cellulose, 5-15 parts of a polycarboxylate superplasticizer, 4-8 parts of sodium gluconate, 3-9 parts of tetraethyl orthosilicate, 4-10 parts of hexasaccharified dicalcium, 2-4 parts of perfluorooctyl triethoxysilane, 1-3 parts of polyvinyl alcohol and 10-20 parts of water. The invention also discloses a preparation method of the concrete pumping agent. The pumping agent provided by the invention has high strength and stable performance, has high fluidization, adhesive aggregation, lubrication and set retarding efficacy, and also has a widerange of application and good water reduction performance.

Description

technical field [0001] The invention relates to a concrete pumping agent and a preparation method thereof, belonging to the field of building material manufacturing. Background technique [0002] Concrete is an important building material in the construction industry. Pumping agent refers to the admixture that can improve the pumping performance of concrete mixture. The so-called pumpability means that the concrete mixture can pass through the pipeline smoothly without clogging, segregation, and good viscoplasticity. Traditional pumping agents have low cohesion and are not suitable for large-scale industrial use. With the development of civil construction technology, the requirements for concrete are getting higher and higher, and the application of C60, C80 to C100 high-strength concrete is becoming more and more extensive. Therefore, it is necessary to study a concrete pumping agent to solve the problems of the existing technology. insufficient. Contents of the invent...
