[ 1 ] - Experimental Investigation of the Methods of Evaluating the Bond Strength Between Concrete Substrate and Repair Materials

This investigation was aimed at studying the effect of test methods on bond strength between concrete substrate and repair material. Four test methods with cementations or modified-cementations repair materials, and two surface roughnesses were studied. The methods used were pull-off, slant shear, splitting prism and a new direct shear named Bi-Surface shear test. While the coefficient of varia...
