Preparation process of autoclaving-curing-free lightweight concrete

The invention discloses a preparation process of autoclaving-curing-free lightweight concrete, and relates to the field of concrete. The preparation process comprises the steps that tap water and an additive are poured into a stirring barrel, cement, fly ash and sand are added while stirring is conducted, an air bubble agent is added while stirring is conducted, mixed slurry is poured into a mold, standing curing is conducted, demolding and warehousing are conducted, and then regular watering curing is conducted to obtain the autoclaving-curing-free lightweight concrete. The problems that an existing prefabricated inner partition wall single plate is heavy in weight, the labor intensity of installation workers is high, and a large amount of manpower and material resources are wasted are solved. The autoclaving-curing-free lightweight concrete has good fluidity, slurry self-leveling can be achieved without manual intervention during pouring, autoclaving or heating curing is not needed, demolding strength can b
