Strengths of Recycled Aggregate Concrete Made

1996-3-1 · The properties of the aggregate were also compared. The fine aggregate for recycled and conventional concrete was 100 percent natural sand. 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.

2020-9-1 · Keywords: pushoff; recycled aggregate; shear-friction theory. Date: 9/1/2020. Abstract: To investigate shear transfer in recycled and natural coarse aggregate concrete, 45 pushoff specimens were tested. Replacement levels of natural coarse aggregates by recycled aggregates in concrete mixtures were 0, 30, 50, and 100%.

Durability of Recycled Aggregate Concrete: A Review

2017-3-1 · Generally, a coarse aggregate replacement ratio of 20% to 50% did not negatively affect the performance of recycled aggregate concrete in many cases. The literature overview showed that recycled aggregate concrete performs satisfactorily under various conditions and has a comparable durability to natural aggregate concrete if designed properly.
