Find the most up-to-date version of ASTM D/DM at Engineering ASTM-D Standard Test Method for Marsh Funnel Viscosity of Clay Construction Slurries (Withdrawn ) – bentonite slurry; clay slurry; funnel viscosity;. ISO ; ASTM D, API Recommended Practice 13B Standards. The UTCM Marsh Funnel Viscometer is used for the determination of flow time by.
Stay on Page Continue to Compass. Combining values from the two systems may result in non-conformance with the standard. This test method provides a practical indicator of the viscosity on a routine basis. 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.
Formerly under the jurisdiction of Committee D18 on Soil and Rock, this test method was withdrawn in April in accordance with section Over the years, we have developed our standard operating procedures SOP for quality control testing. 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.
The Marsh Funnel Viscosity test can be used for field quality control asgm slurries. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. This test method allows for the assessment of an apparent viscosity of clay slurries in the laboratory and in the field. It is the responsibility of the user d610 this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Standard Test Method for Marsh Funnel Viscosity of Clay Construction Slurries
Relative changes in slurry viscosity can be identified using Marsh Funnel measurements and modifications can be made to mixing and handling procedures.
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. The most commonly used slurry is a bentonite clay slurry. The values stated in each system may not 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.
This test method provides a practical indicator of the viscosity on a routine basis. Marsh of Los Angeles who published the design and use of his funnel viscometer in Compressive strength testing is typically performed at a third party offsite laboratory as required. Our team utilizes quality control data as a measurement of our success. Our goal is to scrutinize every aspect of our work and tailor our methods in an effort to produce a quality end product.
This test method provides an indirect measurement of the viscosity of clay slurries using a astmm Marsh Funnel and a graduated cup of specific dimensions.
Quality control is the single most important element to ensure proper construction and performance of a cutoff wall in a seepage barrier application.
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.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.
The most commonly used slurry is a bentonite clay slurry. Slurry viscosity is also directly related to filter cake permeability.
Note 2—The quality d690 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.

Link to Active This link will always route to the current Active version of the standard. ACT has developed dedicated portable on-site grout quality control testing laboratories for each of our grouting projects.
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. This test may be used to determine the relative effects of this and other atm materials on the viscosity of a slurry.
The chemistry of cement, flyash, silica fume, water, admixtures, and additives varies from source to source and can vary over time from the same source. 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. Prior to starting each project, we ast conduct a full scale onsite mix testing program to meet project specifics. Inert suspended solids such as fine sands and additives affect the viscosity of slurries.
