Expansive cementitious materials to improve micro-cable reinforcement bond in 3D concrete printing

Microcable reinforcement has been demonstrated as a promising solution for enhancing the mechanical properties of three-dimensional (3D) printed concrete. Generally, inadequate interfacial bonding between simultaneously entrained microcables and concrete matrix limits the general application of microcable reinforcement. This paper proposes a method of automatically including expansive cementitious materials (ECMs) in the cable–concrete interface...
