Mechanical Behavior of Recycled Fine Aggregate Concrete

This study investigated the mechanical behavior of normal strength (NS) and high strength (HS) concrete containing recycled fine aggregates (RFAs). A high slump mixing design was employed, which may be potentially used as filled structural concrete. The compressive strength, tensile strength, and elastic modulus were measured according to the RFA replacement ratio and curing time.

Aggregates are the building blocks of modern civilization.

And estimated 38,000 tons of aggregates are necessary to construct one mile of lane of interstate highway. Constuction of an average modern home requires 400 tons of aggregate. Construction of an average size school or hospital requires 15,000 tons of aggregates. Aggregates make up 94% of asphalt and 80% of concrete.

Why is concrete fire resistant?

The components of concrete – cement (limestone, clay and gypsum) and aggregate materials – are chemically inert and therefore virtually non-combustible. Concrete also has a slow rate of heat transfer, which means that concrete walls in a home act as a fire shield, protecting adjacent rooms from flames and maintaining its structural

Chapter Two

Double and triple barrel designs have been in use since the 1980s. In a double drum, the inner chamber dries the aggregate and drops it to the outer shell where it combines with the RAP. This configuration results in a reduction of emissions and blue smoke, higher production rates, and lower fuel consumption.
