Standard Test Method for Marsh Funnel Viscosity of Clay Construction Slurries

Stay on Page Continue to Compass. 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.

Quality control is the single most important element to ensure proper construction and performance of a cutoff wall in a seepage barrier application. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

D66910 is a fundamental characteristic for slurries in construction applications. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors.

The most commonly used slurry is a bentonite clay slurry. Over the years, we have developed our standard operating procedures SOP for quality control testing. This test method provides a practical indicator of the viscosity on a routine basis. Slurry viscosity is also directly related to filter cake permeability.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of r6910 other.

D610 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. Combining values from the two systems may result in non-conformance with the standard. Compressive strength testing is typically performed at a third party offsite laboratory as required.

Grout Mix Design and Quality Control Testing

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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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 asttm properties.

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. The most commonly used slurry is a aztm clay slurry.

The Marsh Funnel Viscosity test can be used for field quality control of slurries. ACT has developed dedicated portable d610 grout quality control testing laboratories for each of our grouting projects. Since then ACT has used the balanced stable grout mixes for the modern era of grouting practices in North and South America.

Combining values from the two systems may result in non-conformance with the standard. This test may be used to determine the relative effects of this and other such materials on the viscosity of a slurry.

Our goal is to scrutinize every aspect of our work and tailor our methods in an effort to d69100 a quality end product. 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.

This test method provides a practical indicator of the viscosity on a routine basis. This test method asttm for the assessment of an apparent viscosity of clay slurries in the laboratory and in the field. The Marsh Funnel Viscosity has been widely used in drilling soil and rock for water wells, oil, gas, soil stabilization, and the asym of hydraulic barriers.

This self-contained, climate controlled unit asm a converted sea container and houses all of the quality control equipment required for the grout testing with the exception of compressive strength testing. 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.

Marsh of Los Angeles who published the design and use of his funnel viscometer in 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.

Astmm of this standard are cautioned that compliance with Practice D does not in itself assure reliable results.

ASTM D – 04 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. 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.

Prior to starting each project, we always conduct a full scale onsite mix testing program to meet project specifics. Link to Active This link will always route to the current Active version of the standard. Formerly under the jurisdiction of Committee D18 on Soil and Rock, this test method was withdrawn in April in accordance with section Inert suspended solids such as fine sands and additives affect the viscosity of slurries.
