Investigation of Calcination Effect with Using White Bayburt Stone in Soil Stabilization

Abstract

A significant component that makes up civil engineering is structural safety. The safety of the structure depends on the bearing capacity of the soil. The soil may lose its bearing capacity for various reasons. Great numbers of methods have been developed to improve the bearing capacity of the soil. One of these is chemical stabilization by adding different additives to the soil. In this study, the effect of calcination in soil improvement was investigated. White Bayburt Stone, reserved in the Bayburt province of Turkey, was used in its natural state and as white Bayburt Stone calcined at 800 degrees. At rates of 5%, 10%, 15%, and 20%, all kinds of additives were added to the soil, and their influence on the unconfined compressive strength was examined. Curing time of the samples was 7 days. The calcined additive material increased the compressive strength significantly at all ratios. While samples containing 20% White Bayburt Stone showed a 262% increase in strength compared to the natural soil, a 458% increase was detected in samples containing 15% calcined White Bayburt Stone compared to the untreated soil.
