Recycled concrete aggregate RCA are aggregates obtained by recycling clean concrete waste where content of other building waste must be very low below few per cent.Read More
2020-10-15ensp0183enspThe Deakin School of Engineering researchers have discovered ground recycled or waste glass can be used instead of sand when making polymer concrete, a material often used in industrial flooring. Senior engineering lecturer Dr Riyadh Al-Ameri said the addition of glass resulted in a stronger product that was less costly to produce.Read More

2020-3-21ensp0183enspIn this paper, the possibility of utilising foundry sand and recycled coarse aggregate RCA obtained from a ready-mix concrete plant for making self-compacting concrete SCC was evaluated.Read More
Good news, as the demand for concrete rises globally and sand supplies are being depleted. This ability to turn waste or recycled glass into a sturdy and waterproof material makes good economic sense, says Dr Riyadh Al-Ameri, senior engineering lecturer.Read More

The strength of the concrete is inversely proportional to the watercement ratio. In other words, the more water you use to mix the concrete, the weaker the concrete mix. The less water you use to mix the concrete, the stronger the concrete mix.Read More
2019-12-12ensp0183enspWhen the glass-based polymer concrete was subsequently tested, it was found to be significantly stronger than its traditional sand-based counterpart. This research provides the evidence for the construction industry to see the potential of glass as a substitute of sand when making polymer concrete and, potentially concrete.Read More
2019-5-21ensp0183enspThe mixes consisted of 612 mm fraction recycled aggregates and 06 mm fraction natural sand, but no recycled fine aggregates. Five series of concrete blocks using recycled aggregates and different cement contents, and a series of reference blocks were manufactured.Read More
2019-6-17ensp0183enspGround recycled glass can be used as a substitute for sand when making polymer concrete, according to researchers from the Deakin School of Engineering. Polymer concrete, a material commonly used in industrial flooring, uses polymers, typically resins, to replace lime-type cements as a binder.Read More
2020-3-6ensp0183enspConcrete sand is a label that is typically used to describe the coarse washed sand that is a common ingredient in cement and asphalt mixtures. Its grains are larger than those of masonry sand, but a processing and screening process ensures that there are no large rocks or pebbles present.Read More
2018-4-4ensp0183enspDive Brief Finite, a newly developed biodegradable material made from desert sand, matches concretes strength but has half of the carbon footprint, reported Dezeen.Read More
Recycled concrete can produce an alternative aggregate for structural concrete as partial or total replacement. The present work is to study the properties of concrete with replacement of 100 of natural sand by manufactured sand and coarse aggregates by different proportions with recycled concrete aggregates RCA.Read More
The invention provides a recycled aerated concrete block. Recycled concrete powder substitutes 25-50wt of sand to make the recycled aerated concrete block, and the silicon content of the recycled aerated concrete block is controlled at 51.9-71.6wt.Read More

2013-11-28ensp0183enspLove your work with re-cycled concrete. Years ago I constructed a large terrace 9m x 5m off our back deck using variously sized flatish slabs of basalt. It has sunk in places laid just on sand as I wanted to plant between the slabs with mondo grass. As it was done in stages, the whole lot needs re-arranging and levelling.Read More

Concrete Sand from Southern Crushed Concrete is a fine aggregate that is used in the production of concrete or mortar. Concrete sand is crushed in a quarry then filtered to ensure no large rock fragments are left behind. When mixed with cement and water, a grout is formed that fills the voids between the coarse aggregate.Read More
2020-9-20ensp0183enspIn late 2018, the University of Melbourne contacted Hanson and suggested a pilot program of using waste materials in concrete, specifically waste glass. 18 months later, Hanson recently completed their first pour using recycled glass in concrete.. Traditionally, concrete is made from a combination of cement, sand and aggregate.Read More
2019-1-7ensp0183enspConcrete is recycled by using industrial crushing equipment with jaws and large impactors. After the concrete is broken up, it is usually run through a secondary impactor and is then screened to remove dirt and particles and to separate the large and small aggregate.Read More
