Research on Winter Construction Technology of Concrete in Outer Tank of LNG Storage Tank
With the proposal of the"double carbon"goal,the development of the new energy industry has accelerated,and the LNG storage tank project has emerged.The outer tank of the storage tank generally involves the construction of mass concrete,such as winter,the construction difficulty is greatly increased,affecting the durability and stability of the storage tank.This paper takes a large storage tank project in Beijing-Tianjin-Hebei as the research object,through a series of methods such as raw material temperature control,mixing process parameter adjustment and heat preservation measures during transportation,the positive temperature state is achieved until the concrete reaches the freezing critical strength.
