Laboratory Evaluation of the Performance of Recycled

produced by recycled brick aggregates has a lower quality than the concrete produced by natural stone aggregates. Furthermore, it was suggested to use the brick aggregate concrete in constructing the walls bearing low load or partitionwalls.

Research and Analysis of Mechanical Properties of Fiber

The emergence of recycled concrete (recycled aggregate concrete for short) provides a new approach to the recycling of resources, [1], for the recycling of resources. A series of physical measures such as crushing, washing and so on are used to make aggregate, and the concrete mixed with cement and so on is called recycled concrete.
