The Importance of Concrete Recycling

Aggregate base course (road base) The largest application of recycled concrete aggregate (RCA) is for the aggregate base course in road construction.This term refers to the center layer of the roadbed. A cross-section of pavement would show dirt, or subgrade, as the lowest of three levels, layered on top by aggregate base course, and finally capped on top by pavement, either concrete

Strengths of Recycled Aggregate Concrete Made Using

1996-03-01· Two sources of recycled aggregate (crushed concrete pavements from U.S. 23 and 1-75 projects in Michigan) and one source of natural aggregate (crushed limestone) were used. Two maximum sizes of aggregates, two levels of water-cement ratio, and two levels of dry mixing time of coarse aggregate were selected to perform the experiments based on a full factorial design.

In the present investigation, an attempt was made to study the influence of the strength of parent concrete on the properties of recycled aggregates and recycled aggregate concrete. In this study, four grades of normal concrete mixes: M20, M25, M30, and M40 were considered as parent concrete to produce the recycled coarse aggregates and recycled aggregate concrete.

Review of Research on and Implementation of Recycled

Rahal [15, 16] tested the mechanical properties of recycled aggregate concrete with a compressive strength 20–50 MPa and compared the results to those of concrete made with natural aggregate. The results showed that the compressive strength, indirect shear strength, and modulus of elasticity of recycled aggregate concrete were all within 10% of those of natural aggregate concrete having the
