电站电工部技术規范5~50中第54条規定,每澆筑混凝土500立方公尺,必須取样品一組測定其抗滲性。如果混凝土抗渗性标号为B_4,那末試騐的压力加到6个大气压此較妥当。此时试騐需进行48小时(不包括试件的裝卸时間)。显然的,在混凝土澆筑
Electrical Engineering Department of the Ministry of Electric Power 5 to 50 in Article 54 provides that every 500 cubic meters of concrete pouring, must take a sample of the measured impermeability. If the impermeability of concrete is labeled as B_4, then it is better to add 6 atmospheres to the test pressure. At this point the test takes 48 hours (excluding the loading and unloading time of the specimen). Apparently, pouring in concrete
