一、事故和原因的分析一九八六年渤海造船厂建造了两栋五层楼家属住宅,建筑面积为3300m~2。施工单位六至八月间浇注了各层混凝土阳台板共五十处,并作了十组混凝土试块,代表了十层混凝土阳台板构件。十月份分两次对十组混凝土试块作了抗压强度试验。报告表明,全部试块均未达到设计要求的200号混凝土抗压强度。其中七组在150号以上,两组为130号,还有一组仅96号。为此,我们寻找了其原因。
I. Analysis of accidents and causes In 1986, Bohai Shipyard built two five-storey family homes with a building area of 3,300 m2. The construction unit poured a total of 50 concrete balcony boards in each floor between June and August, and made ten sets of concrete test blocks, representing ten-story concrete balcony board members. Ten compressive strength tests were performed on ten concrete blocks in October. The report shows that all the test blocks failed to meet the design requirements of the 200th concrete compressive strength. Seven of these groups were on the 150th, with 130 in the two groups and 96 in the group. For this reason, we sought out the reasons.
