Description

technical field [0001] The invention relates to a medium-efficiency 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 medium-efficiency concrete pumping agent to solve the existing problems. Insufficient technol...
