This paper reviews specific technical and eco-efficiency performance issues in using glass waste as an aggregate in the production of concrete. Eco-efficiency is a relatively modern tool in the pursuit of sustainability. Eco-efficiency is the concept of maximising the benefits from the use of non-renewable resources while minimising the Concrete made with large-size recycled aggregates is a new kind of recycled concrete, where the size of the recycled aggregate used is 25–80 mm, which is generally three times that of conventional aggregate. Thus, its composition and mechanical properties are different from that of conventional recycled concrete and can be applied Sustainability Free Full-Text Discrete Element Simulation MDPI

Due to the presence of old mortar (OM) and interfacial transition zone (ITZ), recycled concrete aggregate (RCA) is inferior to natural aggregate (NA). The purpose of this paper was to study the effect of accelerated carbonation on the macro-properties and micro-properties of RCA under different pressure (0.05, 0.15, 0.30 MPa).

Most recycled concrete is used as aggregate in road sub-base. When well cleaned, the quality of recycled concrete aggregate is generally comparable to virgin aggregate. The possibilities for use are equally comparable although the use of crushed concrete in new fresh concrete is rare. Recycled aggregate accounts for ~6% to 8% of aggregateThe demand for sustainable construction materials has driven the exploration of various innovative approaches to enhance the properties of concrete for reducing its environmental impact. The present study examines the effects of incorporating recycled concrete aggregate (RCA), slag cement, alccofine, and glass fibers into Experimental Investigation on Ternary Blended Recycled Aggregate
