Studies on recycled aggregates-based concrete

Waste Management & Research: The Journal for a Sustainable Circular Economy, 2006
Reduced extraction of raw materials, reduced transportation cost, improved profits, reduced environmental impact and fast-depleting reserves of conventional natural aggregates has necessitated the use of recycling, in order to be able to conserve conventional natural aggregate.

Relationships between recycled concrete aggregates characteristics and recycled aggregates concretes properties

Construction and Building Materials, 2016
Abstract This research aims to analyze the quality and suitability of recycled concrete aggregates (RCA) produced by crushing concrete blocks provided from building demolition waste by comparison to natural ones in providing concretes for building structures.

Recycled Concrete Aggregates

2015
This chapter describes the main features of Recycled Concrete Aggregates (RCAs). An overview of the previous works available in literature is firstly presented. Then, the experimental activities performed on RCAs for the present research are described and discussed.

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.

Constitutive Formulations for Concrete with Recycled Aggregates

2017
In this Chapter, a thermodynamically consistent gradient model is proposed for natural aggregate concrete and then, modified to take into account the addition of different contents of recycled aggregates and its influence on concrete mechanical response.

Recycled concrete as an aggregate for concrete—a review

Matériaux et Constructions, 1978
The present state of knowledge on the use of recycled concrete as an aggregate in new concrete is reviewed and suggestions made as to what further work is necessary before a proper assessment of the material can be made. Where crushed uncontaminated concrete is used the properties of the material as an aggregate and the basic engineering ...
