Effect of Recycled Coarse Aggregate Type on Concrete ...

13-05-2014  Using multilinear correlation analysis, the influences of these aggregate characteristics and other parameters on the properties of recycled aggregate concrete were evaluated. The results showed that the performance of the concrete containing each type of RA was largely influenced by the aggregate nature and quality, in addition to attached mortar content.

Effect of recycled coarse aggregate on concrete ...

22-06-2011  The skeleton effect of coarse aggregate increases with the increasing strength of coarse aggregate, and normal coarse aggregate plays the highest, whereas the lowest concrete strength occurs when using the weak recycled coarse aggregate. There is a linear relationship between the concrete strength and the corresponding mortar matrix strength.

27-07-2019  The reuse of materials from destroyed structures as recycled aggregate for concrete has become an important issue, especially in Iraq’s Mosul City following the war of 2017. Many water types which are unacceptable for drinking, such as the well water available in Mosul, may be used in concrete, avoiding the need to use precious potable water. In this study, the effects of non-potable well ...
