Abstract:

Past studies have investigated the influences of biochar addition on the nutrient removal and saturated conductivity properties of soils. Literature survey showed that there is a gap in the amount of work devoted to studying the effects of biochar addition on strength and volume change properties of soils. If biochar amended soils are to be used as geo-environmental construction materials, their mechanical behavior needs to be examined in depth. This project describes a laboratory-based experimental program that was conducted to study the mechanical properties of a mid-atlantic native intermediate silty sand that was amended with different biochar volume percentages. The effect of compactive effort is specially scrutinized on biochar amended soils. Results are interpreted and comparative discussions are made with respect to the limited studies found in the literature. Speculations are made on biochar’s potential as a viable ground improvement material for geo-environmental engineering applications.
