RESEARCH ON TEMPERATURE CRACK PREDICTION AND CRACK CONTROL MEASURES DURING THE CONSTRUCTION OF CONCRETE OUTER TANKS FOR LNG STORAGE TANKS
Large volume concrete pouring is a key link in the construction of LNG storage tank foundations.During the curing period,it releases a large amount of cement hydration heat,which forms huge tensile stress under the joint action of the internal and external environment.Along with the corresponding tensile strength of concrete,it leads to a decrease in the overall integrity,waterproofing,and durability of the structure.Based on the foundation engineering of the liquefied natural gas storage and transportation project of a company,a systematic study is conducted on its construction process,and the formulated construction methods are scientifically and practically tested.Corresponding prevention and control measures are proposed,in order to lay a theoretical and practical foundation for quality monitoring and management in the construction process of major warehousing,transportation,storage and other engineering projects in China's future.
