Induced shear in reinforced concrete beams with synthetic aggregate
Revista IBRACON de Estruturas e Materiais, 2023 The increasing aluminum production demands larger volumes of bauxite residue (BR) to be stored in the Amazon region. There are millions of tons of waste without reuse but with high potential for use in civil construction as artifacts or components for ...

The fire retardant effects of huntite in natural mixtures with hydromagnesite [PDF]
The fire retardant effects of natural mixtures of huntite and hydromagnesite have been investigated. As well as being entirely natural these mixtures of minerals can be considered “greener” and more environmentally friendly, in their production methods ...

Use of inorganic fertiliser in place of poultry manure for rehabilitation of gold and bauxite ore refining residues [PDF]
, 2000 Ore refining residues are difficult substrates for revegetation because they often contain extremely low plant available levels of one or more essential elements (Hossner and Hons 1992).

Anti‐Slip Material‐Based Strategies and Approaches
Advanced Materials Technologies, EarlyView.This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.

American Journal of Industrial Medicine, EarlyView.ABSTRACT Background Mining workers are exposed to a range of respiratory hazards, including respirable dust. While exposure to respirable crystalline silica in the mining industry has been found to be common, less is known about trends in measured levels of exposure to respirable dust overall.

Coarse bauxite residue for roadway construction materials [PDF]
International Journal of Pavement Engineering, 2013 About 25 million tonnes of bauxite residue (BR) from alumina refining are generated in Australia each year. Managing this residue is costly, and the reuse of coarse BRs is becoming an increasingly attractive and sustainable solution to the problem. Using coarse BR in road construction has the potential for large volume reuse.
