| Popis: | Implementing waste materials in construction applications represents an effective solution for many waste management problems. This study presents an innovative solution for application of treated oil sands waste (TOSW) in grout mixtures used for micropiles construction. Effects of employing these grout mixtures on micropiles cross-section, surface interface properties and axial behaviour were investigated. The results showed an enhancement in the grout body diameter for micropiles installed using the developed grout, while maintaining the micropile surface properties. Micropiles installed using grout incorporating a high percentage of the TOSW (up to 30%) exhibited the same axial behaviour as that of micropile installed using conventional grout. Therefore, incorporating TOSW in micropile applications has high potential for producing cost efficient micropiles along with providing a green oil sands waste management solution. |
