The base spec indicates a 21 second minimum requirement for the flow cone test, but the specialty subcontractor has already asked to relax the requirement to 16 sec. Statistical analysis of the flow test data converted Marsh flow time into viscosity. Your Alert Profile lists the documents that will be monitored. For grout with palygorskite the viscosity was at least twice that of the other grouts. Defense manufacturing is all about project manufacturing and project accounting. The pipe flow tests gave

Standard Test Method for Flow of Grout for Preplaced-Aggregate Concrete (Flow Cone Method)
We have no amendments or corrections for this standard. This method of test covers the procedure to be used both in the laboratory and in the field for determining the flow of grout mixtures by measuring the time of efflux of a specified volume of astm c939 from a standardized flow cone.
Asym standard is also available to be included in Standards Subscriptions.
Scientific Research An Academic Publisher. The flow cone shall be firmly mounted in such a manner that the top will be level and the cone free from vibration use level, rigid, horizontal surface.

Grout Flow Cone (ASTM C939/ASTM C6449)
Stopwatch accurate and readable to astm c939. We are using 16″ astk ACIP piles with psi grout, with depths in excess of feet. This standard is not included in any packages. The fluidity controls the ability of grout to penetrate fractures and can be determined by pipe flow tests, Marsh funnel tests, mini-slump cone tests and rheometer tests. Defense manufacturing is all about project astm c939 and project accounting.

A charge of the erythrocyte test by automated method. Researching on the web also reveals that this is a common configuration. The rheological properties of xstm grouts containing talc or palygorskite were investigated for optimizing fluidity and quick strengthening at injection. Your Alert Profile lists the documents that will be monitored. 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.
