Grout Flow Cones and Sets
HM-372, HM-372B, HM-373, HM-373B & HM-371
Please refer to ASTM C939 Standard Test Method for Flow of
Grout for Preplaced-Aggregate Concrete (Flow Cone Method)
for exact test procedure.
Grout Flow Cones measure the flowability of hydraulic grout
used in preplaced aggregate concrete. Flowability is measured by
time of discharge of a 1.725L sample of grout through an 0.5in
(12.7mm) ID discharge tube orifice from the cone. The cast alumi-
num Flow Cones all come with an adjustable point gauge assem-
bly to indicate initial sample level.
Gilson Grout Flow Cones can be purchased in a number of dif-
ferent configurations best suited for your application and needs
and feature replaceable orifice discharge tubes:
HM-372 Grout Flow Cone Set is supplied complete to meet
ASTM C939 requirements. An 0.5in (12.7mm) Orifice is already
installed, and a 3-Legged Steel Support Stand, and 2L (2.1qt)
stainless steel Beaker for use as a receiving container are also
included.
HM-373 Grout Flow Cone Set is identical to the HM-372 set,
but has a 0.75in (19mm) Orifice to be used with alternate test
methods.
Set Components:
• HM-372A Painted Steel Stand is 20.5in (414mm) high.
