如何防止温差裂缝，是大体积混凝土的技术关键。防裂型ＦＳ－Ｈ混凝土防水剂用于大体积混凝土中，降低了水化热，补偿了混凝土的冷缩，提高了混凝土的抗裂、抗渗能力，延长了结构伸缩缝的间距，成功地解决了大体积混凝土的若干技术问题。
How to prevent temperature cracks is the key to the technology of mass concrete. Anti-cracking type FS-H concrete waterproofing agent is used in large volume concrete to reduce the heat of hydration, compensates the concrete for cold shrinkage, improves the crack resistance and impermeability of concrete, and extends the spacing of structural expansion joints. Successfully Solved a number of technical problems of mass concrete.
