碾压混凝土静力弹性模量的相关分析

Analysis of Static Elastic Modulus of Roller Compacted Concrete(RCC)

抗裂性能好的碾压混凝土一般应具有较高的抗拉强度、较低的弹性模量。本文在总结国内大量碾压混凝土工程试验数据的基础上对碾压混凝土静力弹性模量进行分析,提出碾压混凝土抗压及抗拉弹性模量增长率、抗压弹性模量与龄期以及抗压强度与抗压弹性模量的关系式,从而可以为工程设计和试验提供理论参考。

Roller compacted concrete （RCC） with favorable cracking resistance always means higher tensile strength and lower elastic modulus. Static elastic modulus of RCC was analyzed in this paper according to a great deal of engineer data of RCC project. Four regressive equations which will provide reference for engineering practice were approached, including growth rate of compressive/tensile elastic modulus with age, compressive elastic modulus with age, compressive elastic modulus with strength.
