Cement is an effective agent in stabilizing the fine grained Niger delta soils to provide base course material for roads. The amount of cement required to stabilize the clays/silty clays and the uniformly graded medium to fine sand can be reduced by as much as 50% if the two soil types are mixed in equal proportions (1 : 1 ratio) before cement stabilization.

Tests on three groups of Australian arid zone soils indicate that cement is a more effective stabilizing agent than lime. Sandy soils rich in gypsum and bassanite do not respond to stabilization. The cement stabilized clayey soils must be adequately protected against increase in moisture content.
