Seismic characterization of recycled aggregate concrete
… environmental benefits of recycling waste concrete and reusing it as aggregate for structural concrete, but the use of Recycled Aggregate Concrete (RAC) is yet limited to non-structural applications such as road sub-base. Widespread application of RAC in areas such as seismic design …

Processing and properties of recycled aggregate concrete
As interest in sustainable materials such as recycled aggregate concrete (RAC) rises, effort, it is important to understand the properties of RAC that relates to its use in construction. To respond to this need, various tests were performed to investigate the properties of RAC. Properties of RAC …

Bond Performance between Corroded Steel and Recycled Aggregate Concrete Incorporating Nano Silica
… and bond performance of steel reinforced recycled aggregate concrete incorporating nano-silica under both normal and corrosive environmental conditions. The experimental part includes testing of 180 pull-out specimens prepared from 12 different mixtures. The main parameters studied were …

Equivalent CO2 Emissions and Construction Costs of Buildings Designed Using Recycled Aggregate Concrete
… concerns and lack of a sustained source of aggregate resources, have resulted in increased research dedicated to concrete produced with a variety of recycled and secondary materials. Despite the environmental benefits of recycled concrete aggregate (RCA), compared with conventional …

Modeling recycled aggregate concrete crack by extended finite element method and concrete damage plasiticity
Crushing concrete to bring the aggregates back to be used for concrete structures is a process of creating recycled aggregate (RA). Recycled aggregate concrete (RAC) has become increasingly important in the field of construction. The use of recycled aggregate concrete made from recycled aggregate …

Performance Enhancement of Concrete Produced with Treated Demolition Waste Aggregates
Recently, the utilisation of recycled aggregate from construction and demolition waste in civil engineering applications has proved to be an eco-friendly approach to overcome the current environmental concerns. Nevertheless, the poor quality of recycled aggregate and the high uncertainty of …

Quality improvement of recycled concrete aggregate using polymers
<p>Crushed concrete is one of the main resources for sustainable material. As this material should not be wasted, this research aims to assess the reuse of crushed concrete material as a resource of sustainable construction material. In this thesis, two types of polymer were mixed with crushed …

Applications of Geopolymer in Civil Engineering: Feasibility Study of Loess Stabilization and Waste Concrete Recycling
… the Portland cement industry, which is used for concrete production and as the conventional soil stabilizer, is not environment friendly; (3) qualified natural aggregates for concrete production are being depleted; and (4) great amount of construction & demolition waste (C&D waste) is being …
