The use of recycled aggregate in replacing natural aggregate in concrete construction has become popular among researchers.

(PDF) Use of recycled concrete aggregate in concrete: A review

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 ...

Use of recycled concrete aggregate in concrete: a review ...

Aug 24, 2015· AbstractThe 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 the negative environmental impact of the aggregate ...

Recycled Aggregates - cement.org

Mar 29, 2013· After demolition of old roads and buildings, the removed concrete is often considered worthless and disposed of as demolition waste. By collecting the used concrete and breaking it up, recycled concrete aggregate (RCA) is created (Fig. 1).This paper focuses on coarse RCA which is the coarse aggregate from the original concrete that is created after the mortar is separated from the …

recycled concrete Topic

Mar 01, 2019· Recycled Concrete. Definition: hardened concrete that has been processed for reuse, usually as aggregate.- ACI Concrete Terminology. The reason for recycling is the reduction of waste in order to protect nature against pollution, the increasing shortage of suitable dumping grounds, and to save energy and natural resources.

Recycled construction and demolition concrete waste as ...

One of the possible solutions to these problems is to recycle construction and demolition concrete waste to produce an alternative aggregate for structural concrete. Recycled concrete aggregate (RCA) is generally produced by the crushing of concrete rubble, screening then removal of contaminants such as reinforcement, paper, wood, plastics and ...

Effects of Recycled Aggregate on Concrete ... - hindawi.com

The unit weight of the concrete ranged from 2365 to 2175 kg/m 3, depending on aggregate content (Figure 6).Increasing the recycled aggregate content reduces the unit weight and density of the concrete, resulting in lighter concrete (Figure 6).The unit weights of the 15%, 20%, and 25% mixes were reduced by 8%, 11%, and 11.5%, respectively, compared to plain concrete.

Use of Recycled Aggregate Concrete - IOSR Journals

properties of recycled fine aggregate and recycled coarse aggregate & also compares these properties with natural aggregates. Basic changes in all aggregate properties are determined and their effects on concreting work are discussed at length. Similarly the properties of recycled aggregate concrete are also determined. Basic

To improve the structural application of steel fiber-reinforced concrete with recycled aggregates (SFRC-RA) composited in gradation by large-particle natural coarse aggregate and small-particle recycled coarse aggregate, the large eccentric compression behavior of eight SFRC-RA columns was experimentally investigated in this paper. The main parameters considered were the strength of the …

Recycling of Brick Aggregate Concrete as Coarse Aggregate ...

Jul 07, 2015· Based on this investigation, it is revealed that recycled brick aggregate can be used as coarse aggregate for making concrete of strength 20.7 to 31.0 MPa. For the same mix design, the recycled aggregate concrete produces almost similar strength compared with the first class brick aggregate concrete commonly used in Bangladesh.
