一、前言混凝土结构物的抗渗性,一直是水电工程、地下工程、及建筑工程所关注的一个主要问题.不少水工建筑物由于渗漏严重而危及建筑物的安全并缩短了使用寿命.过去,为了提高混凝土结构物的抗渗性,大多采用加大水泥用量、减小水灰比和使用优良材质等各种方法.但是,这些措施给大体积混凝土的温控带来了困难,针对这一问题,开发使用了 I. INTRODUCTION The impermeability of concrete structures has been a major concern for hydropower projects, underground engineering and construction projects, and many hydraulic structures endanger the safety of buildings and shorten the service life due to serious leakage In the past, in order to improve the impermeability of concrete structures, most of them used various methods such as increasing the amount of cement, reducing the ratio of water to cement and using fine materials, etc. However, these measures have brought difficulties to the temperature control of mass concrete, In response to this problem, the development and use of the
