However, the strain rate response of concrete in tension and compression in all range of strain rate differs much. In compression strain rate sensitivity should be investigated in two domains, because of the shift of test results. The reason of division is probably connected with influence of ...
aIn contrast to the strength, the flexural modulus of the composites increases gradually with the amount of reinforcement and reaches a saturation value of around 6 GPa with 20–35 % MWCNTs. 与力量对比,综合的flexural模数逐渐增加以相当数量增强并且到达饱和值为大约6 GPa与20- 35% MWCNTs。[translate...
There are many factors that affect the compressive strength of concrete. The relationship between compressive strength and these factors is a complex nonlinear problem. Empirical formulas commonly used to predict the compressive strength of concrete are
