The durability of recycled aggregate concrete containing recycled masonry aggregate
AIP Conference Proceedings, 2021This paper presents research results of recycled aggregate concrete testing. The main aim of this contribution is the verification of physical and mechanical properties and durability of concretes where natural aggregate is replaced by recycled masonry aggregate originated from construction and demolition waste.

Green recycled aggregate concrete
Construction and Building Materials, 2013Abstract The paper presents results of experimental investigation of concrete made with recycled concrete aggregate, low cement content and high content of different mineral supplements. Such concretes belong to “green” or “eco” concretes, since they have less impact on the environment, help in solving the problem of construction and industrial waste

Research on Carbonation of Recycled Aggregate Concrete Using Different Recycled Concrete Aggregates
Applied Mechanics and Materials, 2014Experimental research on carbonation resistance of recycled aggregate concrete was conducted. Two kinds of recycled aggregates were considered, which were from road waste concrete blocks and waste concrete specimens in lab. The test results showed that the carbonation depth of RAC using the aggregates above increased by 11%, 17% at 28d compared with ...

Abstract The subject of concrete recycling is regarded as very important in the general attempt for sustainable development in our times. In a parallel manner, it is directly connected with (a) increase of demolition structures past out of performance time, (b) demand for new structures and (c) results––especially in Greece––of destruction by natural

Alkali-aggregate reaction in recycled aggregate concrete
Journal of Cleaner Production, 2020Abstract Using recycled concrete aggregate (RCA) to substitute original aggregate (OA) is of significance for sustainable development of construction materials. However, uncertainties remain with respect to the long-term durability of concrete containing RCA.

Worldwide research has shown that there exist clear differences between properties of recycled coarse aggregates (RCA) and those of natural coarse aggregates (NCA), such as porosity, water absorption, low surface density, higher crush value. According to the specific performance requirements of concrete, choosing appropriate raw materials, then ...

Studies on recycled aggregates-based concrete
Waste Management & Research: The Journal for a Sustainable Circular Economy, 2006Reduced 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.

Recycled aggregate (RA) has been used in various construction applications around the world, mainly as sub-grade, roadwork and unbound materials, but not in high-grade applications. This paper examines relationships among demolished concrete (DC) characteristics, properties of their RA and strength of their recycled aggregate concrete (RAC).

Closed-loop recycling of recycled concrete aggregates
Journal of Cleaner Production, 2012Reduce, reuse and recycle for environment recovery and respect are the key principles of a sustainable construction material. Much research has been conducted regarding the use of recycled concrete aggregates (RCA) in concrete mixes recycled from parent concrete of natural source aggregates, referred here as first generation.
