The Environmental Impact of Recycled Concrete

Water absorption of masonry recycled aggregates, concrete recycled aggregates and the mixtures of two ones must be a maximum of 20%, 10% and 3% respectively in mass of aggregates (Rilem, 1994). Sagoe-Crentsil et al (2001) investigated the relation between fine natural aggregates and coarse

Recycled Aggregate Self Compacting Concrete: A Sustainable

Sustainability of Using Recycled Concrete Aggregates as

It is common practice in the U.S. to crush old concrete pavements at the end of their service lives into recycled concrete aggregate and then reuse them in the base course of new pavements. It is not, however, common to use the recycled concrete aggregate (RCA) in the new concrete pavement itself.

Recycled Concrete - Lehigh Hanson, Inc

More recently a third type of aggregate has emerged: recycled concrete aggregate (RCA) which is produced by crushing concrete reclaimed from demolished highways, buildings and other structures. Aging infrastructure, scarce landfill space, cost savings and environmental benefits all fuel the growing demand for concrete recycling.
