An overview of the problem of D-cracking in portland cement concrete (PCC) is provided, and the Iowa pore index test for determining the quality of coarse aggregate for concrete is evaluated. The Iowa pore index test was developed to evaluate the durability of coarse aggregate. The test measur...
[118] incorporated CBA as a cement alternative in ultra-high-strength concrete in uniquely high-strength mortars. Brake et al. [88] investigated the influence of pulverized CBA as a partial alternative for cement with recycled coarse aggregate in the concrete mixture. There were two different ...
The related test device for concrete anti-crack performance comprises: an inner constraint column, an outer cubic die, and a base with a locating pin on middle to connect the column. This invention needs simple matched devices and operation method, has explicit evaluation index, and fit to cont...
