Effect of Chemical Additives on Strength of Dune Sand-Lime-Fly Ash Mixtures Cured at Low Temperature

Dune sand was treated with three different fly ashes mixed with two kinds of lime and with cement. The mixtures were treated with small amounts of sodium chloride, sodium metasilicate, sodium carbonate and sodium hydroxide and cured at 43 ºF. The specimens were tested after 7, 28 and 90 days. Sodium metasilicate was the most effective and sodium chloride the least. Dolomitic monohydrate lime gave better results than calcitic hydrated lime. Cement gave better results in short curing periods. The author has done more research on the stabilization of dune sands with different products.
