通常混凝土的抗拉强度是其抗压强度的8%-15%, 一些研究者也提出过其它的关系式, 以后有机会再详细描述. 在结构设计中, 一般不考虑混凝土的抗拉强度, 即假设混凝土的抗拉强度为0, 但在筑路工程(Pavement Engineering)中, 我们需要考虑混凝土的抗拉强度. 本笔记简述混凝土抗拉试验的基本原理及过程。 2 直接测量方法 直...
7.4.2 Compressive Strength Although the flexural strength of concrete pavement is responsible for resisting the bending load of the traffic, compressive strength is still commonly used in specifying the strength requirement of concrete pavements as the test is relatively easier and reliable to perform....
where i represents the primitive value of data, Si is the value of data after scaling, and imaxand iminare the values of maximum and minimum values of primitive data, in the order mentioned. Tables3and4introduce the experimental raw data values of compressive strength used to develop the four...
Results showed that the water requirement and density of fiber reinforced roller compacted concrete pavement (FRRCCP) were slightly higher than those of RCCP. The compressive strength was found to decrease by 1–2% with an increase in fiber content. However, flexural strength, toughness, and ...
The concrete tiles with 15% (LS2) partial substitution had the highest average flexural and compressive strengths, while the tiles with 45% (LS4) partial substitution had the lowest average values. As to the type of solid waste material, the study revealed that the concrete tiles with ...

The addition of 10% silica fume increased both the compressive strength and frost resistance of the RCC mixtures; however, it significantly decreased the workability of fresh mixtures. The pumice made the specimens more workable, but had a negative impact on both the compressive strength and frost...
