Concrete waste is presently recycled and used as a road base material or, alternatively, landfilled, while it has the potential to be recycled to produce recycled concrete aggregate (RCA) to replace natural coarse aggregate (NA) in structural concrete.
Based on the investigation and the analysis of results, valuable data were obtained regarding the concept and practice to the reuse construction debris based on LCA. Keywords: Life cycle assessment, Feasibility study, Recycled aggregate, Recycled aggregate concrete, Cost effectiveness, Environmental impact, Simulation, Thermal power station.
Properties Of Air Entrained Recycled Aggregate Concrete Akinkurolere Olufunke Olanike Abstract: The use of recycled aggregate as a replacement for natural aggregates has been known for a number of years. The future benefits of using recycled aggregate cannot be overemphasized. This study was an attempt to evaluate some hardened properties if ...
tries such as recycled industrial wastewater, foundry sands, glass and other materials that would typically end up in landfills. In addition to the use of SCMs in the concrete mix, concrete from demolition can be crushed and recycled as aggregate. Recycled aggregate is often .
However, a comprehensive stateoftheartdocument on the recycled aggregate concrete has been presented by Hansen others in 1992 in which detailed analysis of data has been made, leading towards preparation of guidelines for production and utilization of recycled aggregate concrete.
Abstract: A study on the application of recycled aggregate concrete for structural concrete was carried out under the concept of life cycle assessment (LCA) for environmental management of construction utilizing recycled products.

Today, the use of coarse recycled concrete aggregates is higher than before, but the fine fractions 0–4 mm and 0–8 mm still lack applications with an added value. The properties of fine recycled aggregates are worse than those of coarse recycled aggregates and they are less investigated compared to the coarse recycled aggregates.
The model considered the plasticity of concrete and the concretetoconcrete contact properties, and was found to agree with experimental data from shear transfer tests. The verified model was then used for a parametric study that investigated lateral reinforcement, concrete strength, and recycled coarse aggregate (RCA) replacement ratio.

Recently, recycled aggregate concrete (RAC) technology has become an effective way to utilize construction waste resources [11, 12]. By the socalled RAC technology [13–15], the construction waste can be recycled, crushed, washed, and graded and then mixed to form recycled aggregates with a certain proportion and grading. After that, the recycled aggregates are used to replace partially or completely .
Mar 06, 2017· Objectives of Study • To design Recycled Concrete Aggregate (RCA) mix for sub base course. • To determine the basic property of subbase material as per MORTH (V revision). • To study the Compaction characteristics of RCA material stabilized by varying dosages of 0%, 1%, 3%, 4% and 5% of Portland cement by weight of RCA mix.
The rate of reduction of recycled aggregate concrete is up to 20% when compa red with natural aggregate concrete. The specimen shearing failure pattern is observed at supports of a beam.
