The Theoretical Research And Practice Of Mass Concrete Of Civil Defense In Fuxin City

By assaying some different concrete test blocks, which were mixed with the different bulking agents, and analyze the assaying data. So we can find the best bulking agent and its blending to utilize in practice. To use a great finite element analysis software of ADINA to simulate the pouring process of foundation mat. And utilize the General Postprocessor of ADINA to draw up the concrete pouring and completed process of temperature distribution. Therefore, the scheme utilizes the concrete pouring process of civil air defense shelter in Fu Xin. To utilize the regression analysis to analyze the bulking agents, which are AEA,HLC,UEA. And then, using ADINA to analyze the UEA and simulate the concrete pouring process of foundation mat. During the working process, it ensures to achieve the requirements of design to pour the mass concrete by controlling the temperature fracture. So the construction can be completed on time.
