The Marsh Funnel Viscosity has been widely used in drilling soil and rock for water wells, oil, gas, soil stabilization, d69110 the application of hydraulic barriers. Slurry viscosity is also directly related to filter cake permeability.
Prior to starting each project, we always conduct a full scale onsite mix testing program to meet project specifics. Viscosity is a fundamental characteristic for slurries d69100 construction applications. This self-contained, climate controlled unit is a converted sea container and houses all of the quality control equipment required for the grout testing with the exception of compressive strength testing.
The values stated in each system may qstm be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
ACT was one of the first grouting contractors to promote and practice the use of balanced stable grout mixes for grouting projects, which began in x6910 the Radioactive Waste Encapsulation and Containment project at Oak Ridge, Tennessee.
Note 2—The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used.
Norma ASTM D/DM
Since then ACT has used the balanced stable grout mixes for the modern era of grouting practices in Atsm and South America. This test may be used to determine the relative effects of this and other such materials on the viscosity of a slurry. Marsh of Los Angeles who published the design and use of his funnel viscometer in Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Compressive sstm testing is typically performed at a third party offsite laboratory as required. ACT has developed dedicated portable on-site grout quality control testing laboratories for each of our grouting projects.
This test method provides a practical indicator of the viscosity on a routine basis.
Standard Test Method for Marsh Funnel Viscosity of Clay Construction Slurries
Over the years, we have developed our standard operating procedures SOP for quality control testing. Inert suspended solids such as fine sands and additives affect the viscosity of slurries.
Although the general range of concentrations of materials is portable from project to project, the exact same mix designs rarely result in identical grout rheology grout properties. Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results. Astk test method provides a practical indicator of the viscosity on a routine basis.
Link to Active This link will always route to the current Active version of the standard. Relative changes in slurry viscosity can be identified using Marsh Funnel measurements and modifications can be made to mixing and handling procedures.
Our team utilizes quality control data as a measurement of our success. The Marsh Funnel Viscosity test can be used for field quality control of slurries. Our goal is to scrutinize every aspect of our work and tailor qstm methods in an effort to produce a quality end product. Stay on Page Continue to Compass.
This test method allows for the assessment of an apparent viscosity of clay slurries in the laboratory and in the field. In slurry wall construction and other applications, the viscosity of a slurry must be maintained at a level high enough to assist in stabilizing the trench walls. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D – 04 Standard Test Method for Marsh Funnel Viscosity of Clay Construction Slurries
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. The aatm of cement, flyash, silica fume, water, admixtures, and additives varies from source to source and can vary over time from the same source.
This test method provides an indirect measurement of the viscosity of clay slurries using a funnel Marsh Funnel and a graduated cup of specific dimensions. The most commonly used slurry is a bentonite clay slurry. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. In this test, it is assumed that the apparent viscosity of a slurry is directly related to the flow duration through a specially shaped funnel the Marsh Funnel.
Formerly under the jurisdiction of Committee D18 on Soil and Rock, this test method was withdrawn in April in accordance with section
