Recycled aggregates are produced from recycled materials which include recycled concrete, brick and masonry. Can be a single sized material typically 20 mm, 14 mm, 10 mm or 7 mm. Fine Aggregate is aggregate less than 5 mm. Coarse Aggregate is normally greater than 5 mm. Can be a single sized material or a graded aggregate consisting of a blend

Improvement of tensile strength with the addition of RCA would usually be associated with an improved elasticity; however, because the “recycled aggregates are more prone to deformation than raw aggregates,” the weakness of the aggregate reduces the Young’s modulus for concrete when RCA is used (Exteberria et al. 2007).

Marie [15] discovered that concrete using aggregate that had been recycled twice (2nd generation) had greater properties compared to concrete using aggregate that had only been recycled once (1st generation). Etxeberria et al. [16] suggested that RA should be sourced from recycled low strength concrete as it provides for a cleaner aggregate

This paper discusses the suitability of producing concrete with 100 % recycled aggregate to meet durability and strength requirements for different applications. Aggregate strength, gradation, absorption, specific gravity, shape and texture are some of the physical and mechanical characteristics that contribute to the strength and durability of concrete. In general, the quality of recycled

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.

Recycled concrete aggregates (RCA) consist of particles with sizes ranging from 3/8-inch to 1.5 inches. Typical uses include concrete coarse aggregate and construction applications. Sizes and designations vary by location due to governing agency requirements and/or application. Contact a sales representative for more information.

Concrete mix with 30% recycled aggregate had the lowest chloride penetration after 2 weeks of saturation and performed better than a concrete mix with 100% natural aggregate. Owing to the lower density and higher water absorption of recycled aggregates, chloride ion diffusion increased with increasing recycled aggregate content beyond 2 weeks.
