Abstract

To obtain the main objective of this research, several sub-objectives were individually addressed which led to water content data, temperature distribution data and visual qualification of the thermal performance of each grout. This thesis concentrated on acquiring the temperature distribution data and evaluating the performance of the individual bentonite grouts utilizing the water content, temperature, and visual data. Four sub-objectives that led to the completion of the research included: 1. Design, construct and install a data acquisition system to monitor temperature distributions in specially-designed containers that simulate a vertical borehole containing the bentonite grout and surrounding soil. 2. Develop control software to control the data acquisition hardware and to log bentonite and soil temperatures at specified time intervals. 3. Test various bentonite grouts in two different soils under two different temperature conditions and monitor temperature distribution as a function of time. Measure water content distribution following each test and visually inspect the bentonite sample for shrinkage and cracking. 4. Analyze the data and categorize the different bentonite in terms of their thermal performance.
