Web18 mei 2024 · Values ranged from 380 to 650 seconds per quart. In the lower-solids slurry, Marsh funnel data showed far more consistency: 39- and 40-second readings all day long. Our own testing of these samples showed even less consistency at high solids than the customer reported. Source: CETCO Drilling Products. Source: CETCO Drilling Products. Web1 mei 2005 · The Marsh cone test is a workability test used for specification and quality control of cement pastes and grouts. It belongs to the family of the orifice tests as the V-funnel [1] or the ORIMET developed by Bartos et al. [2]. The Marsh cone test standard varies from one country to another, but its principle is usually the same.
