Description

technical field [0001] The invention relates to the technical field of concrete additives, in particular to an environment-friendly autoclaved pipe pile water reducer and a preparation method thereof. Background technique [0002] With the rapid development of engineering construction technology and the continuous updating of foundation treatment engineering construction technology and mechanical equipment, high-strength concrete prestressed static pressure pipe piles have been widely used in the foundation treatment of high-rise building projects in large and medium-sized cities. Commonly used concrete members. At present, my country's pressure pipe piles are mainly produced by the two-stage production process of atmospheric pressure steam curing + high pressure steam curing. When the medicine reaches the predetermined strength, it must go through two processes of steam curing and high temperature and high pressure steam curing. This production process consumes a lot of en...
