A STUDY ON RECYCLED CONCRETE AGGREGATES

2018-3-15  RCA. The recycled aggregate concrete is made by mixing 60% of recycled aggregates with 40% of crushed stone chips. The aggregates used for concrete batching are maintained at saturated surface dry condition . The workability of the recycled aggregate concrete is slightly lower than that of the conventional concrete. The

A Comprehensive Review on Recycled Aggregate and

Recycled concrete aggregate was used in all the investigations except for Kou et al. (Kou et al., 2014) (recycled mortar aggregate). The CO 2 pressure and the treating duration are listed in the legend varied between cases, as indicated in the legends. A tendency can be observed that the relative compressive strength due to carbonation increases as the RA replacement ratio increases.

Special Issue "Advances in Recycled Aggregate

Accordingly, the primary performance of low-quality recycled aggregate concrete could be improved by varying the replacement ratio of the recycled aggregate and using appropriate mineral admixtures such as fly ash and ground granulated blast-furnace slag. The results show the potential for the use of low-quality aggregate in structural concrete.

Recycled Aggregate - an overview ScienceDirect Topics

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 quality than natural concrete.

Performance of Recycled Fine-Aggregate Concrete

In this context, use of recycled fine aggregate (RFA) from construction and demolition (CD) waste can be considered as an effective elucidation. Conventional mix proportioning of RFA in concrete can not be used. To address this issue, a novel mix-proportioning method is developed using particle packing density and minimum paste theory.

The Effect of Recycled Aggregate Quality on Concrete ...

Recycled aggregate was produced by crushing the waste concrete from buildings. Two types of concrete mixtures were tested namely concrete made fully using normal aggregate as a control concrete and another type of concrete made using recycled coarse aggregate (25, 50 and 75% coarse recycled aggregate replacement were used).
