Viscosity is a fundamental characteristic for slurries in construction applications.
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.
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. Referenced Documents purchase separately The documents listed below are referenced asstm the subject standard but are not provided as part of the standard. The most commonly used slurry is a bentonite clay slurry. Quality control is the single most important element to ensure proper construction and performance of a cutoff wall in a seepage barrier application.
Grout Mix Design and Quality Control Testing
This test method provides a practical indicator of the viscosity on a routine basis. Stay on Page Continue to Compass.
ACT was one of the first grouting contractors to promote and awtm 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. Prior to starting each project, we always conduct a full scale onsite mix testing program to meet project specifics. Formerly under the jurisdiction of Committee D18 on Soil and Rock, this test method was withdrawn in April in accordance with section Compressive strength testing is typically performed at a third party offsite laboratory as astk.
Link to Active This link will always route zstm the current Active version of the standard. 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.
Our goal is to scrutinize every aspect of our work and tailor our methods in an effort to produce a quality end product. Slurry viscosity is also directly related to filter cake permeability.
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. Inert suspended solids such as fine sands and additives affect the viscosity of slurries. Users of this standard are cautioned that compliance with Practice D f6910 not in itself assure reliable results.
Over the years, we have developed our standard operating procedures SOP for quality control testing. 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 of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
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 most ashm 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.
Standard Test Method for Marsh Funnel Viscosity of Clay Construction Slurries
The Marsh Funnel Viscosity f6910 been widely used in drilling soil and rock for water wells, oil, gas, soil stabilization, and the application of hydraulic barriers. 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.
This test method provides a practical indicator of the viscosity on a routine basis. Combining values from the two systems may result in non-conformance with the standard. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. ACT has developed dedicated portable on-site 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.
ASTM D – 04 Standard Test Method for Marsh Funnel Viscosity of Clay Construction 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. This test may be used to determine the relative effects of this and other such 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. 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.
Combining values from the two systems may result in non-conformance with the standard. Marsh of Los Angeles who published the design and use of his funnel viscometer in The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Relative changes in slurry viscosity can be identified using Marsh Funnel measurements and modifications can be made to mixing and handling procedures.
