WebGrout Flow Cone Set. Grout flow cones measure the flow of grout for preplaced aggregate concrete. The flow cone method works with neat grout. Grouts containing fine aggregate capable of passing a No. 8 sieve, and grouts having 35 seconds or less efflux time. Time of discharge of a 1.725L sample measures flowability of grout through the 1/2 … WebThe efflux time on the modified flow cone test must be less than 30 s after 1 h to pass the test. In the past, the HTGF test was a requirement for FDOT’s standard specifications. The HTGF test, however, is expensive and cumbersome to conduct in a typical construction materials testing laboratory.
