Using Nano Materials for Stabilization of Subgrade Soils
Abstract
xperimental study was carried out on a sample of a clay soil selected from Al-Marg district, Cairo, Egypt to represent atypical Egyptian expansive clayey soil. Modified proctor, unconfined compressive strength (U.C.S) and free swelling (swelling%) testshave been used to evaluate using hydrated lime and Nano slag (N.S) as stabilisers on the compaction characteristics, strength andswelling properties of soils. The results revealed that UCS of the test soil generally increased with an increase in the total binder (T.B%),increased with an increase in curing period and also increased with an increase in N.S/T.B ratio up till a specific value and thendecreased. The swelling% decreased with an increase in the T.B%, decreased with an increase in curing period and also decreased withan increase in N.S/T.B ratio up till a specific value and then decreased. The optimum ratio of N.S/T.B which gives the maximum U.C.Sand minimum swelling%, was found to be between (0.15 and 0.30).Keywords: Stabilisation, Clay, Nano slag, lime, swelling soil. 1. IntroductionThe typical cross section of an Egyptian road pavement is 20 to 30 cm of granular base courses made of compacted wellgraded crushed stone, covered by one or more layer of asphalt concrete (Abdelkader, 1981). This pavement systemis not suitable for a subgrade of expansive clays as it cannotwithstand the effects of the movement of the subgrade, andreplacement of the expansive clay by granular materialswould necessitate extra material being imported thusincreasing the cost of construction on expansive soils. To suppress swelling and reduce volume change and to increasethe strength of expansive clay soils and thus decrease therequired thickness of the sub-base or base layers,stabilisation of these types of soil is necessary.Since the development of soil stabilisation technique in the1960s, many additives have been used such as lime andordinary Portland cement, Sargent (2015).Dolomitic lime, fly ash, steel slag and conventional limehave been used in soil stabilisation.
