Uniaxial compressive behaviors of fly ash/slag-based geopolymeric concrete with recycled aggregates

Cement & Concrete Composites, 2019
The uniaxial compressive stress-strain behaviors of fly ash/ground granulated blast furnace slag (GGBFS) geopolymeric concrete containing recycled aggregate were investigated in this study.

Sustainability assessment of recycled aggregates concrete mixes containing industrial by-products

Materials Today Sustainability, 2019
Virgin natural aggregates make up approximately 80–85% of the volume of concrete commonly used by Western Australian councils in their infrastructure. These councils generate a huge amount of construction and demolition (C&D) waste, most of which is sent

Durability of Recycled Aggregate Concrete

2014
Recycled aggregates (RA) are now well-known to be suitable for structural concrete production. The employment of RA (obtained from concrete or ceramic waste) in recycled aggregate concrete (RAC) production as a structural material has been widely analysed and validated in many applications.

Effects of Recycled Aggregate Characteristics on Performance Parameters of Recycled Aggregate Concrete

SP-192: 2000 Canmet/ACI Conference on Durability of Concrete, 2000
This study points out the close relationship between several quality indicators of recycled aggregate and the performance of recycled aggregate concrete. Regarding the diversity in quality and composition of the recycled concrete products, three laboratory produced air-entrained-concretes with low, medium and high water-cement ratios and a non-air ...

Properties of recycled aggregate and recycled aggregate concrete: effect of parent concrete

Asian Journal of Civil Engineering, 2018
In the present investigation, an attempt was made to study the influence of the strength of parent concrete on the properties of recycled aggregates and recycled aggregate concrete. In this study, four grades of normal concrete mixes: M20, M25, M30, and M40 were considered as parent concrete to produce the recycled coarse aggregates and recycled ...
