Webb25 juni 2024 · This work is a systematic study of the strength and ultrasonic properties of cemented paste backfill incorporating a foaming agent, known as foam-cemented paste backfill (FCPB). Based on determining the optimal admixture contents (foaming stabilizer, thickening agent, and foaming agent), a series of uniaxial compressive strength (UCS) … Webb3 feb. 2024 · It has been shown that slurry fluidity is inversely related to its concentration, but 78% is the “stopping point” for the deterioration of fluidity. The addition of rod-milled …

WebbThe lower strength CLSM can be readily excavated. Since CLSM Slurry is designed to be fluid and self-leveling, it can be easily placed as backfill in a hole or trench. Slurry can be placed in one lift with minimal labor and no vibration or tamping. Using CLSM reduces trench width and excavation since there is no compaction needed. http://ce561.ce.metu.edu.tr/files/2013/11/slurry-trench-wall-2.pdf greenwood archer capital
