This paper describes a preliminary investigation on factors related to the use of recycled concrete aggregates (RCA) in precast/prestressed concrete applications.
This document summarizes a study on recycled concrete aggregate conducted by G. Saichander, a 4th year civil engineering student. It discusses what recycled concrete aggregate is, its characteristics, classification, production process, uses, benefits, and disadvantages.
A major portion of this aggregate volume is occupied by coarse aggregates. Therefore, the demand for coarse aggregates is enormous in the construction industry. The increased extraction of coarse aggregates from the natural resources is required to meet this high demand. The increasing use of natural coarse aggregate (NCA) creates an ecological ...
This research work aims at making one such experiment where recycled aggregates are produced from C&D waste thus paves a way, for the effective management of concrete debris.
This paper presents an overview of previous studies on the environmental impact (EI) and toxicity of producing recycled concrete aggregates (RCA), fly ash (FA), cement, superplasticizer, and water ...
Recycled Concrete Aggregates. ET 493 Instructor: Cris koutsougeras Advisor: Mohamed Zeidan By: Chase Charrier AND Garrett tregre. Introduction.
This document discusses recycled concrete aggregate (RCA) which is obtained from construction and demolition waste such as broken concrete, bricks, and road pavement.
Lesson: Concrete Technology - Building Materials The quality of aggregate affect the durability and strength of concrete. Since about 3/4 of the volume of concrete is occupied by aggregate.

This document provides information on various tests conducted on aggregates that are used in construction. It describes the aggregate abrasion value test, which determines the abrasion resistance …
The use of recycled concrete aggregate (RCA) in concrete as partial and full replacements of natural coarse aggregate is growing interest in the construction industry, as it reduces the demand for aggregate. In addition, the use of RCA leads to a possible solution to the environmental problem caused by concrete waste and reduces …
Exploring the durability properties of Recycled Aggregate Concrete based on some recent researches in this area. Durability issues associated with Recycled Aggregates presented and mitigation measures suggested.
3. INTRODUCTION Recycling is the act of processing the used material for use in creating new product. Aggregates obtained from recycling of construction and demolition waste. Recycled aggregate are comprised of crushed, graded inorganic particles processed from the materials that have been used in the constructions.
In this study, the recycled plastics are used in the concrete by partial replacement of coarse aggregate in concrete. The main purpose of this study is to investigate the properties of concrete such as workability, compressive as well as tensile strengths in the partial replacement of aggregate.
Jitender and Sandeep ( 2014) [5] compared the properties of recycled aggregate and natural aggregates, stated that replacement of NA by RCA will effect on chloride ions resistance and ...

Recycled aggregate concrete (RAC) specimens with different recycled coarse aggregate replacement ratios by mass (R) are fully immersed in a 10% chloride solution for 235 days. Both free chloride concentration (C f ) and total chloride concentration (C t ) are then measured employing a rapid chloride test (RCT) system. The Fick's …
Crushed recycled concrete can be used as gravel for construction projects or as the aggregate in new concrete mixtures, providing it is free of contaminants. Using recycled concrete reduces costs and pollution compared to using newly quarried materials, and keeps concrete debris out of landfills.
Among the construction waste that could be recycled, we can mention the aggregates resulting from crushed concrete. While the acquired knowledge about the use of recycled aggregates in new ...
