对“碾压混凝土抗裂性能的研究”一文的商榷

Deliberation for the paper of research on anti crack property of roller compacted concrete

对《水力发电》2004年第4期上发表的“碾压混凝土抗裂性能的研究”一文中碾压混凝土抗裂指数计算公式进行评价,认为该公式存在没有考虑徐变变形,没有交代约束系数与养护条件系数如何取值,以及公式物理意义不明确等问题。为此,提出了考虑因素全面、公式物理意义明确的抗裂指数计算公式。

Appraising crack resistance index calculation formula of roller compacted concrete the author think this formula has some defects no considering creep restraint factor and curing condition factor no transferring how gain and the formula physical meaning is indeterminating. For this reason the author advances the crack resistance index calculation formula which all influential factors are considered and physical meaning of formula is expliciting.
