mix design of recycled aggregate concrete

Mix design for recycled aggregate thermal insulation

In addition, some researchers have considered a combination of recycled aggregate concrete and thermal insulation concrete. This type of concrete, called recycled aggregate thermal insulation concrete (RATIC), is composed of natural gravel, recycled gravel, cement, sand and thermal insulation material all mixed with water.

RECYCLED AGGREGATE CONCRETE The Constructor

The aggregate particles of recycled concrete compare well to conventional mineral aggregates in that they possess good particle shape, high absorption, and low specific gravity. Recycled aggregate concrete has also been shown to have no significant effect on the volume response of specimens to temperature and moisture effects.
