Thickening time of cement slurry
Web25 Jun 2024 · Based on the water film thickness theory [29,46], increased thickening agent content inevitably leads to decreased thickness of the water film wrapped on the surfaces of tailings and/or cement particles, which may cause a decrease in slurry fluidity. However, the thickening agent increased the consistency of the slurry, which contributed to bubble … WebAdditional benefits to the fresh cement slurry properties, such as a reduction of the thickening time (i.e. decreasing the "wait on cement time"), make it a viable alternative to …
