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 ...

From his own half, Vinícius Júnior delivered a ball with the outside of his right foot to a streaking Endrick up top, who chipped the goalkeeper to put Real Madrid up 2–1 on aggregate.

This paper analyzes the mechanical characteristics of HPC using the American Concrete Institute (ACI-211.1-91) guidelines, substituting cement with 17% fly ash (FA) and 10% silica fume (SF), and ...

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 ...

Abstract: This study presents a novel approach to predict the compressive strength of concrete incorporating recycled coarse aggregate using machine learning models. The research begins with an ...

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 ...

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 ...
