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 virgin aggregate when used in new concrete. An example of a mix design using recycled aggregates in a pavement application is shown following table.
PRECAST CONCRETE TECHNOLOGY Ready mix concrete is same as regular concrete the only difference is that it is manufactured by a automated and computerized system as per the required quantity in a centralized location. This is then delivered to the construction site in truck
Reactive powder concrete is extremely workable durable and yields ultra-high strengths without using coarse aggregates. Reaching compressive strengths of 30000 pounds per square inch psi this new-age concrete also has tensile strength with the inclusion of steel and synthetic fibers.
