近年来,混凝土特别是大体积混凝土在水利工程、土木工程及建筑工程等行业中得到了广泛应用,技术发展非常迅速,成就十分突出,可以预见混凝土在未来仍将是一种重要的工程材料,并在材料、结构、施工技术等各个方面仍会得到进一步发展,在实际的施工中,我们虽然采取了许多措施,但大体积混凝土裂缝问题仍不断出现,这引起了大 In recent years, concrete, especially mass concrete has been widely used in water conservancy, civil engineering and construction industries. The technology is developing very rapidly with outstanding achievements. It is foreseeable that concrete will remain an important engineering material in the future, And in the material, structure, construction technology and other aspects will be further developed in the actual construction, although we have taken many measures, but the mass concrete cracks continue to appear, which caused a large
