Anchor bolt Pull Out Strength is the force required to pull a single bolt out of its foundation The separation can occur between the epoxy grout and the concrete foundation or it can occur between the anchor bolt and the epoxy grout itself This bulletin provides the formulas needed to calculate the force required to pull an anchor bolt out in either manner To calculate the Total
E 2 1 Investigation Test Loading Procedure The anchor should be loaded to failure R a or to a proof load P p which should be limited to 0 80 P tk or 0 95 P t 0 1k whichever is the lower The anchor should be loaded to the maximum test load in a minimum of six cycles see Figure E 1 The load cycles and minimum periods of observation are given in Table E 1 Where creep
Standard Procedure for Testing Water Based Drilling Fluids to check the density of each batch of mixed grout prior to placement If the State elects to test compressive strength perform the following Grout Cubes Cast a mold set three 3 grout cubes for every 50 yd3 of grout placed in accordance with the procedure contained in Materials Bureau Test Method NY701 19E Grout

Our anchor load pull out testing service will provide the answers and help determine the next course of action to take Normally performed to establish the strength of fixings that have been installed or fitted into walls amp roofs our pull out tests are vital for commercial buildings railways and airports There are many factors that can affect the strength and durability of eye bolts
anchorage test for fully grouted bolts Standard pull tests have sometimes been employed but they provide no information on the anchorage near the top of the bolt An alternative first described more than 25 yrs ago in the U S is the short encapsulation pull test SEPT With this test the bolt is installed with only a short 1 ft or
