2019-1-1 Recycled concrete aggregates require more energy to crush than recycled mortar aggregates, a finding primarily related to the aggregate size of composite cement particles. Improvement in the segregation of cement paste tends to enhance the recycled aggregate quality and use under different stress conditions, such as compression, impact and ...

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).

In order to ensure the quality of recycled aggregate after crushing, it is necessary to carry out secondary crushing if the particle size can not meet the requirements after primary crushing, so it is needed to add a screening system to screen the concrete blocks with larger particles and transport them back to the crusher for re-crushing.

2013-3-29 After demolition of old roads and buildings, the removed concrete is often considered worthless and disposed of as demolition waste. By collecting the used concrete and breaking it up, recycled concrete aggregate (RCA) is created (Fig. 1).This paper focuses on coarse RCA which is the coarse aggregate from the original concrete that is created after the mortar is separated from the rock
