This substitute flow test is applied to control of work for preparing large-sized steel-reinforced concrete joints in precast-concrete manufacture with possibility of substituting for the standard testing method authorized by the Building Center of Japan in July 1997 for SS-mortar, type II. This paper represents results of a study conducted for clarifying relationship of the substitute method to the standard method in order to lay down criteria of the flow for appropriate work control at work site. The test result offers a suggestion that, when in order to conduct properly the control of work for "SS mortar, type II", the J_<14>-funnel value is taken into account in integration with compressive strength, the value of current criterion, 140 ± 25 (115-165) mm in the case of FG1 (φ5×10cm) should be changed to a new value of 165 ± 35 (130-200) mm. Besides, it is recommended newly to adopt control values, 120 ± 30 (90-150) mm for FG2 and 150 ± 40 (110-190) mm for FG3 (setting vessel), in regard to the new control method.
