Flow cone efflux time

Web1.3 This test method is intended for use with grout having an efflux time of 35 s or less. 1.4 When efflux time exceeds 35 s, flowability is better determined by flow table, found in Test Method C109, using 5 drops in 3 s. 1.5 The values stated in … Webefflux time was measured according to ASTM C939 (Standard Test Method for Flow of Grout for Preplaced-Aggregate Concrete - Flow Cone Method 2010). The flow cone test consists of measuring the time of efflux of 1725 ml [0.06 ft3] of the grout through a specific cone having a 12.7 mm [0.5 in.] discharge tube (Figure 1). Moreover, the
