摘要
用一次冻结模式探讨了不同初始强度下负温防冻剂砼性能。研究表明:初始冻结强度在宏观规模析冰的一次冻结法中为非敏感参数,无法确定负温砼抗冻临界强度。
The property of concrete with antifreezing admixtures at minus-tern. environment was investigated at different initial strength by freezing only once. Research showed that the initial strength is not sensive under the situation of macroice-separated out. As a result, the critical strength can not be decided by it.
