谈提高二灰碎石基层强度和避免裂缝的措施

Methods of Improving the Foundation Layer Strength and Preventing Cracks for Lime-flyash Concrete

从理论分析入手,结合室内实验和工程实践,对二灰碎石的强度、收缩性、疲劳变形与混合料配合比、骨料级配等方面的相互关系,提出几点设计中应考虑的问题。

The relationships among the strength, contraction, fatigue deformation, the proportion of the mixture and aggregate rate of lime-flyash concrete were analyzed through theoretical analysis combining with indoor experiments and engineering practice. Some corresponding considerations during design were presented in the paper.
