Influence of Amount of Recycled Coarse Aggregates and Production Process on Properties of Recycled Aggregate Concrete
TL;DR: In this paper, four different recycled aggregate concretes were produced; made with 0, 25, 50, 50 and 100% of recycled coarse aggregates, respectively, in order to achieve the same compressive strengths.
Journal ArticleDOI
Study on the influence of attached mortar content on the properties of recycled concrete aggregate
TL;DR: In this article, the authors analyzed data from experimental works carried out in CEDEX and also from literature review to obtain experimental relationships between the attached mortar content and other recycled aggregate properties, covering a wide range of different aggregates qualities.
Journal ArticleDOI
Effect of microstructure of ITZ on compressive strength of concrete prepared with recycled aggregates
TL;DR: In this article, the influence of these aggregates (recycled and natural) on the microstructure and compressive strength of the new concrete were studied, and the results are explained by the differences in porosity and pore structure of the two types of aggregates, and possible interactions between the aggregates and the cement paste.
Journal ArticleDOI
Use of aggregates from recycled construction and demolition waste in concrete
TL;DR: In this paper, a review of the international scenario in terms of C&D waste generated, recycled aggregates (RA) produced from construction and demolition waste and their utilization in concrete and governmental initiatives towards recycling of construction and Demolition waste is presented.

Microstructural analysis of recycled aggregate concrete produced from two-stage mixing approach
TL;DR: In this paper, a two-stage mixing approach (TSMA) is proposed to improve the compressive strength for recycled aggregate concrete and hence lower its strength variability, which can fill up some pores and cracks, resulting in a denser concrete, an improved interfacial zone around recycled aggregate and thus a higher strength when compared with the traditional mixing approach.
