Post-Installed Reinforcing in Fire Conditions
HIT-FP 700 R Reduced Cure Time
Figure 6 is intended for the full cure time of the product for in-service loads, including long-term loading. It may be desired to use a shorter cure time for conditions where the full in-service load is not being applied( i. e. temporary loads during construction). For example, if shoring is removed and the resulting load consists of short-term construction loads that are less than the in-service loads this may be possible.
Additional testing has been conducted on HIT-FP 700 R at reduced cure times. Table 5 provides reduction factors that can be applied at 2 and 3 days after installation at various temperature ranges, while Table 6 provides the number of days of t cure at various temperatures that are needed for 75 % of the full bond performance.
HIT-FP 700 R does not have published bond stresses, rather, it has been shown to be equivalent to a cast-in rebar, which does not use bond stress to calculate development length. To use the values in Table 5 or 6, determine the ratio of applied loads for the temporary load case( i. e. loads during construction) vs. the in-service loads ensuring that this ratio is less than the reduction factor, α, in Tables 5 or 6, based on the specific base material temperature for the project during the cure time.
