Prior to starting each project, we always conduct a full scale onsite mix testing program to meet project specifics. Xstm values from the two systems may result in non-conformance with the standard.
The most commonly used asttm is a bentonite clay slurry. The Marsh Funnel Viscosity has been widely used in drilling soil and rock for water wells, oil, gas, soil stabilization, and the application of hydraulic barriers.
Relative changes in slurry viscosity can be identified using Marsh Funnel measurements and modifications can be made to mixing and handling procedures. Slurry viscosity is also directly related to filter cake permeability.
Quality control is the single most important element to ensure proper construction and performance of a cutoff wall in a seepage barrier application. Combining values from the two systems may result in non-conformance with the standard.
Standard Test Method for Marsh Funnel Viscosity of Clay Construction Slurries
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.
Our goal is to scrutinize every aspect of our work and tailor our methods in an effort to produce a quality end product. The chemistry of cement, flyash, d691 fume, water, admixtures, and additives varies from source to source and can vary over time from the same source.
Our team utilizes quality control data as a measurement of our success. 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 x6910 exception of compressive strength testing. Reliable results depend on many factors; Practice D provides f6910 means of evaluating some of those factors.
Formerly under the jurisdiction of Committee D18 on Soil and Rock, this test method c6910 withdrawn in April in accordance with section Marsh of Los Angeles who published the design and use of his funnel viscometer in This test method allows for the assessment of an apparent viscosity of clay slurries in the laboratory and in the field.
Compressive strength testing is typically performed at a third party offsite laboratory as required.
Grout Mix Design and Quality Control Testing
This test method provides a practical indicator of the viscosity on a routine basis. 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.
This test may be used to determine the relative effects of this and other such materials on the viscosity of a slurry. ACT has developed dedicated portable on-site grout quality control testing laboratories for each of our grouting projects. 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.
Over the years, we have developed our standard operating procedures SOP for quality control testing. 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 values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

The Marsh Funnel Viscosity test can be used for field quality control of slurries.
Although the general ast, of concentrations of materials is portable from project to project, the exact same mix designs rarely result in identical grout rheology grout properties. Link to Active This link will always route to the current Active version of the standard. The most commonly used slurry is a bentonite clay slurry.
Inert suspended solids such as fine sands and additives affect d6901 viscosity of slurries. 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 with the Radioactive Waste Encapsulation and Containment project at Oak Ridge, Tennessee.
Norma ASTM D/DM
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. 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.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Viscosity is a fundamental characteristic for slurries in construction applications. Since then ACT has used the balanced stable grout mixes for the modern era of grouting practices in North and South America. Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results.
