On-going research at Texas A&M University indicated that soil stabilization
using calcium chloride filter cake along with Class F fly ash generates high strength.
Previous studies were conducted with samples containing calcium chloride filter cake
and both Class C fly ash and Class F fly ash. Mix design was fixed at 1.3% and 1.7%
calcium chloride and 5% and 10% fly ash with crushed limestone base material.
Throughout previous studies, recommended mix design was 1.7% calcium chloride filter
cake with 10% Class F fly ash in crushed limestone base because Class F fly ash
generates early high and durable strength.
This research paper focused on the strength increase initiated by greater than
1.7% pure calcium chloride used with Class F fly ash in soil to verify the effectiveness
and optimum ratio of calcium chloride and Class F fly ash in soil stabilization. Mix
design was programmed at pure calcium chloride concentrations at 0% to 6% and Class
F fly ash at 10 to 15%.
Laboratory tests showed samples containing any calcium chloride concentration
from 2% to 6% and Class F fly ash content from 10% to 15% obtained high early strength however, optimum moisture content, different mix design, and mineralogy
deposit analysis are recommended to evaluate the role and the effectiveness of calcium
chloride in soil stabilization because of the strength decreasing tendency of the samples
containing calcium chloride after 56 days.
