چکیده مقاله
bond strength between concrete substrate and repair materials is one of the important parameters which affect the performance of patching repair in concrete structures in this paper to study the mix proportions effect on bond strength the effect of several factors including w/c and c/s ratiio aggregate type and grading in cementitious and modified cementitious material with silica fume and latex epoxy are investigated the slant shear test under natural ambient condition has also been used to measure bond strength based on the results obtained increasing the w/c ratio or using fine aggregate with smaller sizes will reduce the bond strength while increasing the c/sratio up to 1/2 5 and using silica sand aggregate will increase bond strength in both ordinary and modified cementitious materials
