Abstract

Three-dimensional concrete printing (3DCP), as an innovative technology, has become increasingly popular owing to advantages such as cost-effectiveness, labor-saving, free of formwork and materials-saving. Using the layer-by-layer construction technique enabled by 3DCP, functionally graded concretes with different ultimate tensile strain (UTS) capacities are proposed in this paper, leading to an optimum design of concrete plates. Three types of concrete, which are designed to have different UTS capacities, namely engineering cementitious composites (ECC), normal concrete (NC) and gepolymer concrete (GC), are developed. Six groups of 3D-printed functionally graded concrete plates are fabricated and tested under…
