Abstract

In the majority of cases this is cement, which is used for soil improvement both for sandy soils and clays in order to increase its strength and reduce its compressibility. However this effect could be reached by using lime or in some cases slag binder for soil improvement. Comparing with cement and lime blast furnace slag used for improvement of soft clays prove more effective. Soils can be improved by means of wet soil mixing or dry soil mixing. The result is that we get a new composite material and its strength is much higher when comparing with natural soils. This technology can be used easily provided that physical mechanism that affects soil behavior of composite material is defined. Mechanical properties of composite material can be defined through its testing using simple as well as complex stress paths, whose are necessary in cases where more complex functional relationships are used. Test results show that soil strength and stiffness properties are highly dependent on the content of slag. Increase in the total water to total solids ratio causes decrease in the mixture strength. Increase in the curing time produced increase in the mixture strength.

Soil Property Improvement Using Slag Binder

Chicago, Illinois
