Abstract The paper presents an experimental study on the effect of plastic fines content undrained behavior and liquefaction susceptibility sand–fines mixtures under monotonic loading. results triaxial compression tests conducted Hostun sand with varying amount (0–20%) type (kaolin calcigel bentonite) are presented. specimens were prepared different initial densities using moist tamping method ...

Long term success of rehabilitation on bauxite-processed residue storage areas is dependant on establishing a capping stratum which will satisfy water use and nutrient cycling requirements of the intended plant community. Bauxite residue sand is the primary growth media for rehabilitating residue disposal areas (RDAs) in Western Australia however; the sustainability of the vegetation cover can ...

The soil moisture content at shearing and other factors, including dry density grain size, influence its shear strength. This study investigated the effect of compaction size distribution on unsaturated Triaxial compression tests were performed in laboratory using modified triaxial apparatus silica sands No. 3 6 without fines with 20% to explore strength characteristics. Test samples compacted ...

We analyze the strategic decision of firms to voluntarily certify corporate social responsibility (CSR) practices in a context where other firms can falsely pretend to be socially responsible. Equilibrium outcomes are crucially determined by consumers' beliefs about the credibility of firms' CSR claims, which depend in turn on the (expected) fines for fraud. First, we show that an increase in s...

The Significance of Dust: Dust studies have already been identified as crucial components of missions to the Moon, Mars, asteroids, and Mercury over the next decade [1,2]. Detailed study of the physical and chemical nature of the fine particulate portion of regoliths of planetary bodies is a key to understanding micrometeorite bombardment and the nature of re-golith formation [e.g., 3]. The Pro...

Soil freezing characteristic curve (SFCC) represents the relationship between soil temperature and unfrozen water content of during thawing processes. In this study, SFCC sandy soils was determined in laboratory. Pure sand mixed with clay at various contents (0, 5, 10, 15, 20% total dry mass), mixtures were compacted to their respective maximum density. Compacted specimens then placed a close r...

Plant sand fixation is the most durable and environmentally friendly mitigation measure for windblown hazards. For aeolian–sand composite soil, fines content main factor affecting pore size distribution characteristics determines soil water retention characteristics. Sandy with uniform particle was used as material, low-plasticity clay a fine particle, soils different were prepared. The evoluti...

In this article we consider the possibility that fines could be collected through the tax and social welfare systems in the same way as higher education contributions and child support payments are currently administered. We argue that the existing system of fine collection and enforcement leads to high default rates and reduces the usefulness of fines as a sanction. We consider a range of mode...
