GW Grab services work with recycled road planings and recycled sharp sand, and we are leaders in making the industry more sustainable. As we have top quality recycled coarse aggregate, you know we constantly maintain the best quality available in the market. You can get a wide array of recycled aggregate, including 10mm and 20 mm.
Recycled concrete aggregate (RCA) is the designation used in BS 8500-2 for recycled aggregate principally comprising crushed concrete. Designations of recycled aggregate other than RCA are of lower quality and may contain significant quantities of masonry which would preclude or limit their use in structural concrete.

2018-12-14 · aggregate. This means that recycled aggregate can perform in the field quite similar strength in concrete when compared to natural aggregate. 3. Performance of RA Concrete In this study, the recycled aggregate was used in making Recycled Aggregate Concrete (RAC). The concrete was
The conversion rate of construction waste into aggregate can reach 85%. One ton of construction waste can produce 0.85 tons of recycled aggregate, 0.01 tons of scrap steel, and the rest is other waste. The selling price of recycled aggregate is about 60% of the natural sand and gravel materials, which can effectively reduce more than 40% of the ...

The use of recycled aggregate, in general terms, causes a reduction in concrete strength (Poon, Shui, Lam, Fok, & Kou, 2004) and elastic modulus, larger creep, and shrinkage deformations (Domingo-Cabo et al., 2009), as well as higher permeability of the concrete (Gómez-Soberón, 2002). In sum, concrete produced with RCA is generally of lower ...
