RAC (recycled aggregate concrete): it is the concrete that had recycled aggregates as a component in the mixing process. recycled concrete aggregates or secondary aggregate: it is the fine and coarse ag-gregate that is produced from processing of the crushed original concrete.

ORCHESTRA: An Object-Oriented Framework for Implementing

Finally, the object-oriented structure of the chemical model definitions makes it possible to implement a new object-oriented framework for implementing chemical models. This framework consists of three basic object types, entities, reactions, and phases, that form the building blocks from which other chemical models are composed.

Concrete Technology - Portland Cement Association

In its simplest form, concrete is a mixture of paste and aggregates (rocks). The paste, composed essentially of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates.

Durability Studies on the Recycled Aggregate Concrete in

Recycling the C&D waste into recycled aggregates (RA) is an effective method for reducing the amount of C&D wastes. Many studies on the properties of RA and the durability of recycled aggregate concrete (RAC) were conducted in China over the past decade.

Batching, Mixing, Transporting, and Handling Concrete, Chapter 10

Most specifications require that batching be done by mass rather than by volume (ASTM C 94 or AASHTO M 157). Water and liquid admixtures can be measured accurately by either volume or mass. Volumetric batching (ASTM C 685 or AASHTO M 241) is used for concrete mixed in con- tinuous mixers.
