Effect of Cement Replacement with Carbide Waste on the Strength of Stabilized Clay Subgrade
Abstract: Cement is commonly
used for soil stabilization and many other ground improvement techniques.
Cement is believed to be very good to improve the compressive and split-tensile
strength of clay subgrades. In some application cement could be partly or fully
replaced with carbide waste. This research is to study the effectiveness of the
cement replacement and to find the maximum carbide waste content to be allowed
for a clay subgrade. The quantities of cement replaced with the carbide waste
were 30, 50, 70, 90, and 100% by its mass. The results show that replacing the
cement with carbide waste decreased both the compressive and split tensile
strength. Replacing cement content with carbide waste reduced its ability for
stabilization. The carbide waste content should be less than 70% of the cement
to provide a sufficient stabilizing effect on a clay subgrade.
