This course discusses how portland cement can be used either to modify or improve the quality of the soil or to transform the soil into a cemented mass with increased strength and durability. The amount of cement used will depend upon whether the soil is to be modified or stabilized. Several different types of cement have been used successfully for stabilization of soils. Type I normal portland cement and Type IA air-entraining cements were used extensively in the past and gave about the same results. At the present time, Type II cement has largely replaced Type I cement as greater sulfate resistance is obtained while the cost is often the same. High early strength cement (Type III) has been found to give a higher strength in some soils. Type III cement has a finer particle size and a different compound composition than do the other cement types.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
