Development of acceptance specifications for tropical gravel paving materials

Engineering Geology, 1983
Abstract The ideal standard grading specification for gravels was meant to ensure high density and stability, and specifications on maximum limits of content of fines, liquid limit and plasticity index were meant to control the magnitude of swell of materials in the pavement structure.

Geophagy in the tropics: an appraisal of three geophagical materials

Environmental Geochemistry and Health, 1997
Geophagy, the deliberate consumption of soil, is a common practice amongst the world's poorer or more tribally oriented people of the tropics. An appraisal of three geophagical samples suggests that Fe is a mineral nutrient which can be supplied to humans in significant amounts via ingested soil. Geophagy provides a direct link between the geochemistry

Performance of OTEC Heat Exchanger Materials in Tropical Seawaters

JOM, 1985
The corrosion of several aluminum alloys in flowing Hawaiian surface seawater and water from 600 m depth for exposure periods up to three years has been studied. The alloys tested in cold water were Alclad (7072) 3003 and 3004; and bare 3004 and 5052). All show some pitting. Pit growth is slow, and pits do not penetrate the cladding. In the warm water,

Influence of tropical climate on properties of polyurethane materials

Adhesives Sealants Technologias
The influence of tropical climate on the changes in properties of polyurethane materials based on simple polyethers, differing in the nature of polyol, diisocyanate component, chain extender or curing agent has been investigated. The results of exposure to natural climatic conditions in the tropics of Southern Vietnam showed that after 6 months of ...
