| Abstract: | Splitting tensile and shearing tests were carried out on a total of 256 cubic bonding specimens to study the bonding behavior between ultra high toughness cementitious composites(UHTCC) and existing concrete.Some factors including the interface roughness,compressive strength,interface moisture states of existing concrete and UHTCC pouring position were investigated.It can be concluded that in the same casting conditions,the effect of the above various factors on splitting tensile strength of the bonding spe... |
