tyre as aggregate replacement in concrete showing that rubber aggregates reduces concrete workability[4] and compressive strength[5]. The strength loss is much more profound when coarse rubber aggregates are used which is due to the low adhesion be-tween these wastes and the cement paste, but several authors rec-

Concrete recycling - Wikipedia

Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill. Crushed rubble can be used for road gravel, revetments, retaining walls, landscaping gravel, or raw material for new concrete.Large pieces can be used as bricks or slabs, or incorporated with new concrete into structures, a material called

Durability of concrete containing aggregate produced from

Minimal information is available on the durability of concrete containing demolished concrete as an aggregate. The purpose of this study was to: investigate and control the reactivity of recycled concrete aggregate (RCA) produced from concrete that was suffering from alkali silica reaction (ASR); and investigate other durability issues of concrete containing RCA with emphasis on salt scaling

PDF) Formulation parameters effects on the performances

Recycled concrete aggregates are composed of natural aggregates more or less covered by hardened cement paste (Abbas et al., 2009; de Juan and Gutiérrez, 2009; Nagataki et al., 2004). Moreover, recycled fine aggregates have a higher water demand compared to coarse recycled aggregates, which makes them harder to be used in concretes and mortars

Authors: Smitha Yadav, Snehal Pathak Abstract: Aggregate compositions in the construction and demolition (C&D) waste have potential to replace normal aggregates. However, to re-utilise these aggregates, the concrete produced with these recycled aggregates needs to provide the desired compressive strength and durability.

Use of recycled asphalt as an aggregate for asphalt

Recycled asphalt is commonly used as an aggregate on pavements, although it is also used as a granular base or subbase, filling material or fillers and stabilized base aggregate. It is on the surface where one can extract the best RAP quality, since the aggregates
