Study on the recycling of recycled aggregated concrete
2011 International Conference on Remote Sensing, Environment and Transportation Engineering, 2011With the development of recycled aggregated concrete researches, and the exhausting of construction materials, it's safe to predict that wider application of recycled aggregated to engineering construction is an inevitable trend. Here a practical problem is presented whether the concrete can be recycled again when the structure constructed by recycled ...

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

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).

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 ...

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 ...

SP-179: Fourth CANMET/ACI/JCI Conference: Advances in Concrete Technology, 1998
A study on the application of recycled concrete for structural concrete was carried out under the concept of life cycle assessment (LCA) for environmental management of construction utilizing recycled products. Such products are often discarded, when existing electric power plants are rebuilt or upgraded in order to meet increasing power demands.

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.

Recycling concrete as fine aggregate in concrete
International Journal of Cement Composites and Lightweight Concrete, 1987Abstract 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.
