Recycled Concrete Aggregate. Recycled aggregate concrete is defined as concrete manufactured with waste materials in order to reduce the negative environmental impact that results from the manufacturing process of cement, achieving a more sustainable product.
The fine recycled concrete aggregates that were used during the entire research program were obtained from an original concrete (OC), of standard composition and properties, which was made in laboratorial conditions, solely for the purpose of being crushed afterwards.
Feb 10, 2014 · At CRUSHCRETE in PA (www.crushcrete.com) we recycle old concrete into a 2A modified, 2B or #57 Aggregate and Screenings products for sale to the general public. This product is a great recycled ...
Recycled concrete will have a higher absorption and lower specific gravity than conventional aggregates. To produce good quality, durable concrete containing a portion of recycled concrete aggregate often requires trial concrete mixes and close monitoring of the properties of the old recycled concrete, with mix adjustments made, as needed.
Whether it is quarried or recycled aggregates or muck away our fleet of tipper trucks and unrivaled delivery service will ensure you are able to complete your job on time and within budget. We aim to recycle 100% of inert construction and demolition waste.
Recycled concrete currently supplies about 5% of aggregate use. The bulk of recycled aggregates – about 68 % – is used as road base. The remainder is used for new concrete mixes (6%), asphalt (9 %) and fill. Recycling concrete features both cost savings and environmental benefits: Reduced disposal of concrete in landfill

2011/06/30 · • Concrete with recycled concrete aggregate has a smaller carbon footprint. • Crushing old concrete to produce aggregate takes less energy than mining virgin aggregate. • Using old concrete helps to conserve virgin aggregate supplies, which are slowly being depleted near larger cities.
About 75-80 per cent of secondary and recycled aggregates are thought to end up as sub-base and fill, including use in road building and airfield pavements. However, the concrete industry actively utilises industrial ecology in the production of modern concrete products due to concrete's inherent inert nature.
