The fineness modulus for fine aggregates was used. Based on the particle size distribution of crushing and grinding products, the production of coarse particles in crushing is the highest (75%), being ...

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 ...

Because these types of fruit consist of so many drupes, they're called aggregate fruit, Jernstedt said. A strawberry is also an aggregate fruit, but instead of having multiple drupes, it has ...

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 ...

Abstract: To quantitatively characterize and evaluate the morphological features of coarse aggregate particles, 2D images of coarse aggregate particles were processed by using Image Pro-Plus software ...
