在第十一次国际大坝会议上,曾有人建议用不收缩混凝土进行筑坝的试验,但尚未实施。早年我院曾提出用补偿收缩混凝土筑坝的设想,认为这样可以加快筑坝速度并降低造价。近年来,我院进行了用低热微膨胀水 At the Eleventh International Dam Conference, it was suggested that tests to build dams without shrinking concrete should be conducted but not yet implemented. In the early years, our institute proposed the idea of ​​compensating and shrinking concrete to build dams, which we believe can speed up the dam construction and reduce the cost. In recent years, our hospital has used low-heat micro-expansion water
