Adhesion studies in view of automated repair using 3D concrete printing

Similar to dental cavities, in that the damaged area must be filled, concrete also suffers from spall damage during long-term service. Inspired by 3D printing a resin patch fits shape of tooth, an automated approach for repair is proposed, where structure filled layer-by-layer. It therefore essential ensure adhesion printed materials. In this study, printable mixtures were formulated and effect adding redispersible polymer powder cellulose ether on materials was investigated. The material fresh hardened stage analyzed using tack test pull-off test, respectively.
