Strength and Slake Durability of Lime Stabilized Pond Ash
Publication: Journal of Materials in Civil Engineering
Volume 19, Issue 7
Abstract
Pond ash, after adequate stabilization, may be suitable for various engineering applications. The effects of lime stabilization on the strength and durability aspects of a class F pond ash, with a lime constituent as low as 1.12%, are reported. Lime contents of 10 and 14% were used, and the samples were cured at ambient temperature of around for curing periods of 28, 45, 90, and . Samples were subjected to unconfined compression tests as well as tests that are usually applied to rocks such as point load strength tests, rebound hammer tests, and slake durability tests. Unconfined compressive strength (UCS) values of 4.8 and and slake durability indices of 98 and 99% were achieved after of curing for samples stabilized with 10 and 14% lime, respectively. Good correlations, that are particularly suitable for stabilized materials of low density and low strength, have been derived for strength parameters obtained from UCS tests, point load strength tests, and Schmidt rebound hammer tests, and also between UCS and slake durability index.
