Display the Results of Some Researcher about the use of Recycled Aggregate in New Concrete

Shamim Abd Hadee Hashim

Abstract: The utilization of recycled aggregate (RA) as filler in the production of concrete can be detailed in the context of eco-friendliness and costs. Its utilization in construction is prevalent in certain developed European and Asian economies. Waste concrete that are by-products from the destruction of concrete structures represents a potential unending supply for the fabrication of concrete aggregates, while the reception of RA in the production of new concrete is dependent upon their respective qualities. The differences between concrete and natural aggregates are due to the presence of a considerable proportion of mortar being linked to the natural aggregates, consequently affecting the properties and the performance of concrete. This work intends to analyze published work and developmental studies on RA, analyze the latest usage of the aforementioned materials in the context of construction, and suggest approaches that could be useful for a wider range of applications. There are quite a few researchers that have worked on of the utilization of recycled waste material in concrete, and evidence of this is present in literature.
