We are using 16" diameter ACIP piles with psi grout, with depths in excess of feet. 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.

Standard Test Method for Flow of Grout for Preplaced-Aggregate Concrete (Flow Cone Method)
Information and observation of the physical characteristics of the sample. 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 grout from a standardized flow cone.
Composition of the sample. Click Here to join Eng-Tips and talk with other members! A charge of the erythrocyte test by automated method. Please first verify your email before subscribing to alerts. Please first log in with a verified email before subscribing to alerts.
Start the stopwatch and remove the finger simultaneously. Stop the stopwatch at the first break in the continuous flow of grout from the discharge opening when the cone is essentially empty. This standard is also available to be included in Standards Subscriptions.
Statistical analysis of the flow test data converted Marsh flow time into viscosity. Scientific Research An Academic Publisher. Close the discharge tube of the cone by placing a finger over the lower end. Your Alert Profile lists the documents that will be monitored.

Stop the stopwatch when the flow stops. I am editing a specification section for Auger Cast Piles. 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 Eng-Tips staff will check this out and take appropriate action.

Grout Flow Cone (ASTM C939/ASTM C6449)
Need more than one copy? If there is a break in the continuity of discharge prior to essential emptying of the cone, it is an indication that the grout is too thick to be properly tested for flow. Level astmm cone by adjusting the mounting forks. Add to Alert PDF. The big Marsh wstm gave values differing by 5. Moisten the inside surface of the flow cone.
