There is an increasing trend toward using recycled concrete aggregate (RCA) in construction. However, concerns have been expressed in laboratory studies about the highly alkaline leachate, high-pH leaching patterns, and release of heavy metals from RCA (e.g., chromium, lead, and arsenic).

Abstract. This research studies on the usage of fly ash (FA) and rice husk ash (RHA) based geopolymers for improving the compressive strength of recycled concrete aggregate (RCA) to be a lightweight stabilised pavement base material.

5 ways recycled concrete can be used: Recycled concrete is used in a variety of ways. Below are some examples. Crushed concrete is the most common form of recycled concrete and can be used as a subbase material for projects such as driveways, foundations, and roads.

We produce a recycled concrete size comparable to #3 stone. It is excellent for erosion control, new driveway bedding and stabilizing parking areas. RC #57. Suitable for a variety of uses including asphalt course-base mix, ready mix concrete, bedding for large pipes and slabs, filter stone and residential drainage.

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 …
