Recycling of Concrete (Recycling Coarse Aggregate) - IJERT

KeywordsRecycled Coarse Aggregate (RCA), Concrete Mix Design(CMD), Natural Aggregate(NA) INTRODUCTION. As we know the term concrete is a mixture of cement + sand + coarse aggregate with water. Concrete is widely used in both substructure and super structure as main constructional material. It is most important substance of a structure.

New Concrete Mix Design for Recycled Concrete Aggregates

As a fundamental building material in modern times, recycled aggregate concrete (RAC) has been subject to continual development. It has evolved from a simple mixture of basic elements, i.e., hydraulic cement, water, and aggregates, to become a modern high-performance material-a material designed to respond to the environment and in some versions to preserve it.

Mix Design Method for Self-Compacting Recycled Aggregate

Mar 03, 2020 · In this method of mix design, the acceptable percentage of recycled concrete aggregate (RCA) depends on the AMC value. Five different batches of design mixes were prepared, including one batch that used conventional design from natural aggregate, two batches that used conventional design from RCA, and two batches that used the proposed design from RCA.
