This paper examines the impacts of the total replacement of Natural Coarse Aggregates (NCA) by Recycled Concrete Coarse Aggregates (RCA) on the mechanical properties in concrete's fresh and hardened ...

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). The ...

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 ...

Rapid Set Asphalt Repair Mix serves as a fast-setting, cementitious repair material with a coarse aggregate blend designed for moderate to deep asphalt repairs. It offers adhesion and durability ...

The work aims to analyze the effect of partial replacement of coarse aggregate by expanded polystyrene (EPS) in the production of hollow blocks, a type of concrete block. Substitution levels, by ...

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 ...

"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 ...
