Evaluation Of A Centrifuge Consolidation Technique To Determine The Effects Of Temperature And Time On Kaolinite Properties, Esteban Miranda Pinzon

Civil Engineering Undergraduate Honors Theses

Abstract

The effects of time and temperature on the moisture content and unit weight profiles, as developed during a centrifuge consolidation process, were observed during the research program that is described herein. Specifically, a Beckman-Coulter Model J6-MI centrifuge with a six-place JS-4.2A swinging bucket rotor was utilized to consolidate kaolinite slurry samples. The consolidation procedure utilized specially designed slurry consolidometers, made from acrylic tubes with inside diameters of 2.63 inches (6.67 cm) and heights of 5.13 inches (13.04 cm). The tested kaolinite slurry samples were created by mixing 400 grams of dry kaolinite clay powder with 200 grams of de-aired …

Kaolinite As An Amendment For Counteracting Hydrophobicity In Artificial Peat-Based Potting Substrates, Sarah Bettany

School of Biological and Marine Sciences Theses

It has been demonstrated in pot experiments at Duchy College Rosewarne, Cornwall, U.K. that adding kaolinite (china clay) to growing media results in an increase in plant biomass. However, the underlying reason for this response is unknown, though, it is speculated that it improves the plants’ ability to tolerate stressful conditions such as heat and drought. In this study four artificial organic substrates (peat, peat/green waste, John Innes no.2 and a bark-based substrate) containing different concentrations of kaolinite (0%, 5%, 10%, 20% and 40%) were tested for capillary rise and water drop penetration time (WDPT). In addition, plant growth experiments …
