experiment of recycle of aggregate concrete

specializing in the production of large, medium and small concrete mixers, concrete mixing stations, stabilized soil mixing stations and other equipment. It is a heavy industry enterprise integrating R & production and sales.

Experimental Research on Quality Parameters of Recycled ...

The experiment was carried out using concrete mixtures, which were combined with natural aggregates and crushed concrete waste (fraction 4/16). The resulting mix of concrete was achieved using natural aggregates, thus replacing natural aggregates with waste, which had partially and fully replaced bulky aggregates with crushed concrete waste.
