半刚性材料的化学反应要持续一个相当长的时间才能完成 ,试件 7d抗压强度试验平均强度 R不满足≥ Rd/( 1- ZαCv)时怎么办 ?半刚性基层的现场强度如何测定 ?使用法国PANDA便携式可变能量动力贯入仪 ,这一问题便可迎刃而解。
Semi-rigid material chemical reaction to continue a long time to complete the specimen 7d compressive strength test average intensity R does not meet ≥ Rd / (1 - ZαCv) how to do? Field strength of the semi-rigid basement how to use? France PANDA portable variable energy penetration device, this problem can be solved.
