摘　　要：通过分析混凝土裂缝产生的原因,提出在混凝土中掺入外加剂能够提高混凝土的抗裂性能。通过介绍UEA—H型混凝土外加剂的化学成分、技术性能特点,得出掺入此外加剂可以控制冷缩裂缝的产生、提高自身结构防水能力。The temperature difference between the temperature stress volume shrinkage of concrete, mass concrete is the main reason for crack, therefore can be achieved through increased compensation shrinkage crack resistance of the concrete role. According to introduce the chemistry ingredient and technology quality featace of UEA—H concrete admixture, can control the appearence of crack, improve its structure proofwater ability.
