Mix design procedure for recycled aggregate concrete - ScienceDirect

Conservation of natural resources and preservation of environment is the essence of any development. Use of recycled aggregate concrete (RAC) is one such attempt and is an answer to some of the problems in constructional engineering. The concept of using RAC is now gaining popularity and research in this direction.

Only up to 10 to 20 percent fine RCA is beneficial. The aggregate should be tested at several substitution rates to determine the optimal rate. Often recycled aggregate is combined with aggregate when used in new concrete. An example of a mix design using recycled aggregates in a pavement application is shown.

Genetic-algorithm-based mix proportion design method for recycled .

ABSTRACT. Several desirable characteristics of concrete, such as strength, slump, durability and low CO2 emission, cannot always be obtained by current conventional mix proportion design methods for recycled aggregate concrete (RAC), because Recycled aggregate generally has lower quality than natural aggregate.
