Replacement of recycled coarse aggregates with natural ...

2016-7-18  In this study we replaced natural aggregates with recycled aggregates in concrete cubes. This is the first part of the study we have to do. Here we are trying to see a pattern of how the strength decrease once we replace natural coarse aggregate (NCA) with recycled coarse aggregates (RCA). The percentages of replacement will be 0%, 50% and 100% ...

2021-11-29  Shrinkage property is a significant indicator of the durability of concrete, and the shrinkage of green recycled concrete is particularly problematic. In this paper, construction waste was crushed and screened to generate simple-crushed recycled coarse aggregate (SCRCA). The SCRCA was then subjected to particle shaping to create primary particle-shaped recycled coarse aggregate (PPRCA).
