摘要
针对游宝坤同志对我们的试验结果和观点提出的质疑 ,基于近期的工作结果 ,就大体积补偿收缩混凝土内部延迟钙矾石生成及其影响进行讨论。大体积补偿收缩混凝土内部存在延迟钙矾石生成现象 ,是否引起膨胀 ,由结构内部条件决定。
Based on our recent researching results,delayed ettringite formation (DEF) in massive shrinkage compensating concrete and its influence on the concrete properties are discussed to reply Mr.You's oppugnations.We confirm that there is DEF in massive shrinkage compensating concrete. Whether is volume expansion induced by DEF is determined by the inner condition of concrete structure.The potential risk of DEF in massive shrinkage compensating concrete should be evaluated seriously.
