Tackling the quality issue in aggregates recycling

“Traditionally, demolition recycling might only have produced crusher run 6F2 and 6F5 aggregates,” says Dolman. “We are able to make high-grade, clean and single-size end products such as sand, 10mm clean, 20mm clean and certified materials for use in construction products.”

Separation processes to improve the quality of recycled

Jan 01, 2013  Abrasion resistance is an important property of aggregates and is often used as a general measure of the aggregate’s quality to resist being worn away or shattered through rubbing, friction and impact under loading or during handling, stockpiling and mixing. RCA are acknowledged to have on average lower abrasion and impact resistance (Los Angeles abrasion loss > 30%) than NA.
