Suitability of Alkali Activated Fly Ash Binder as a Stabilizing Agent for Highly
Expansive Soil
This research work presents part of the research on efficacy of sodium based alkaline activators and class F fly ash as an additive in
improving the engineering properties of expansive soils (Black cotton soils). The cement industry is the second largest industry for
global warming. Sodium hydroxide concentrations of 10, 12.5 and 15 molal along with 1 Molar solution of sodium silicate were used
as activators. The activator to ash ratios (liquid to solid mass ration) was kept between 1 and 2.5 and ash percentages of 20, 30 and
40%, relatively to the total solids. The effectiveness of this binder is tested by conducting the Unconfirmed Compressive Strength
(UCS) at curing periods of 3, 7 and 28 days and is compared with that of a common fly ash based binder; also the most effective
mixtures were analyzed for mineralogy with x-ray diffraction (XRD). Suitability of alkaline activated fly ash mix as a grouting material
is also ascertained by studying the rheological properties of the grout, such as setting time, density and viscosity.
