Bond behaviour of concrete with fine recycled aggregate

IABSE Congress Reports
<p>The recycled aggregate industry allows reusing old structures that need to be demolished. Once crushed, the original concrete can be reused as aggregates for new concrete. However, this recycling technique has some limitations. While coarse recycled aggregates present a more uniform quality and can be used without difficulties, fine recycled ...

Prediction of the elastic modulus and the splitting tensile strength of concrete incorporating both fine and coarse recycled aggregate

Construction and Building Materials, 2019
This study aims to develop models for the elastic modulus (Ec) and splitting tensile strength (ftsp) of recycled aggregate concrete (RAC) incorporating coarse recycled aggregate (CRA) and fine recycled aggregate (FRA).

Understanding the influence of properties of fine recycled aggregates on recycled concrete

Proceedings of the Institution of Civil Engineers - Construction Materials, 2023
Scarcity of fine natural aggregates suitable for concrete, the pollution caused by their mining and the great environmental impact produced by the final disposal of waste concrete, have all motivated several studies about their use as recycled aggregates for concrete, particularly the fine fraction. The use of fine recycled concrete aggregates (FRCAs)

Concrete with fine recycled aggregates: a review

European Journal of Environmental and Civil Engineering, 2013
This paper presents a review of the literature published so far on the use of fine aggregates from construction demolition waste used as a partial or total replacement of fine natural aggregates in concrete production. The review presents the initial works on this subject and an overview of the existing regulations.

Recycling concrete as fine aggregate in concrete

International Journal of Cement Composites and Lightweight Concrete, 1987
Abstract Increasing shortage of natural aggregates for concrete in urban areas leads to a search for aggregates from new sources. This paper examines the use of crushed concrete fines (CCF) produced from ‘waste’ concrete as fine aggregate in concrete.

A green ultra-high performance geopolymer concrete containing recycled fine aggregate: Mechanical properties, freeze-thaw resistance and microstructure.

Science of the Total Environment, 2023
The shortage of natural aggregate poses challenges and offers new opportunities for the construction industry. Under this background, the emergence of recycled aggregates sheds new lights on building aggregate.
