◐ Applicable for use with special installation provisions and installation temperature restrictions to account for short gel time with deep embedment depth . See Instructions for Use ( IFU ) for special installation parameters .
■ Not recommended due to limited gel time of adhesive . 1 Edge distances are determined using the minimum cover specified by ESR-4868 with an additional 6 % of the development length per suggestions for drilling without an aid per Hilti Post- Installed Reinforcing Bar Guide Section 3.3 . Smaller edge distances may be possible , for which development and splice lengths may need to be recalculated . For further information on required cover see CSA A23.1-14 Table 17 ; see Sec . 3.2 for determination of d cs

3 k 1 and k 2 as defined by CSA A23.3 12.2.4 ( a ) and ( b ), are taken as 1.0 for post-installed reinforcing bars . For additional information see May-June 2013 issue of the ACI Structural Journal , “ Recommended Procedures for Development and Splicing of Post-Installed Bonded Reinforcing Bars in Concrete Structures ” by Charney , Pal and Silva .
4 k 4 = 0.8 for 20M bars and smaller bars , 1.0 for 25M and larger bars . See CSA A23.3 12.2.4 ( d ).
5 K tr is assumed to equal zero . 6 Values are for normal weight concrete . For lightweight concrete , multiply development and splice lengths by 1.3 . 7 Development and splice length values are for static design . For tension development and splice lengths of bars in joints , see CSA A23.3 21.3.3.5 . For further information about reinforcement in seismic design , see CSA A23.3 Ch . 21 . 8 Refer to the Hilti North America Post-Installed Reinforcing Bar Guide for further explanation , background information , and design examples . l d mm
