Marsh cone method
WebTHE MARSH CONE TEST The Marsh cone test has been used previously to determine the relative fluidity of cement pastes with superplasticizer [1, 2], utilizing an approach similar to the flow cone tests in the ASTM Standard C 939 for grouts [3] and a recent AFREM recommendation [4]. It is a simple and practical method for obtaining a relative WebMarsh Funnel Viscosity tests in accordance with ASTM D6910 or API Method RP 13B-1; Flow Cone Viscosity tests (MMG) in accordance with ASTM C 939; Grout Newtonian Viscosity, Plastic Viscosity, Apparent Viscosity, and Yield Point tests using Fann Viscometer in accordance with API Method RP 13B-1;

WebMar 1, 2024 · The results indicate that UHSC can be produced successfully using this method by using the lowest water amount among the other methods. In addition, it was found that UHSC obeys the so-called Abrams’ law and its compressive strength can be optimized using 15% silica fume by mass of cement. The Marsh funnel is a simple device for measuring viscosity by observing the time it takes a known volume of liquid to flow from a cone through a short tube. It is standardized for use by mud engineers to check the quality of drilling mud. Other cones with different geometries and orifice arrangements are … See more Based on a method published in 1931 by H.N.Marsh, a Marsh cone is a flow cone with an aspect ratio of 2:1 and a working volume of at least a litre.
