Testing of Bond Between Fresh and Hardened Concrete

Testing Of Bond Between Fresh And Hardened Concrete

Four test methods, reflecting different stress states at the bond between the fresh and hardened concrete, are evaluated. The four methods are a slant shear test, an indirect tension test and two different flexure tests. The slant shear test is shown to be consistent and the most sensitive test in showing the strength of the bond, and was used ...
