"As a major portion of typical concrete is coarse aggregate, replacing all of this with used tire rubber can significantly reduce the consumption of natural resources and also address the major ...

"Coarse aggregates, such as crushed rock and gravel, make up most of a given concrete volume. The mining, processing and transportation operations for these aggregates consume large amounts of ...

The technique involves using newly designed casting moulds to compress the coarse rubber aggregate in fresh concrete that enhances the building material's performance," said lead author and Ph.D ...

Instead, single-sized coarse aggregates are surrounded and held together by a thin layer of cement paste to add strength. Among the main advantages of NFC is economy in materials, higher thermal ...

A recent article in Scientific Reports looks at how gold ore tailings (GOTs) and recycled coarse aggregates (RCAs) can be used as substitutes for river sand (RS) in geopolymer concrete (GPC).

Coconut shells are a waste product that can replace coarse aggregates in concrete up to 10%, maintaining strength. They improve thermal insulation, density, and acoustics, although reducing ...

Due to the scarcity of natural sources of stone aggregates, bricks are widely used as coarse aggregate in concrete and as blocks for making walls. Conventionally, bricks are produced by burning ...
