A feasibility study on the use of fine recycled aggregates in 3D printing concrete KU Leuven
Due to the highly specific printing process in 3D concrete printing (3DCP), the concrete mixtures used during printing need a time-dependent shear thinning property, also named thixotropic behaviour. This particular rheological behaviour of 3D printing concrete is mainly achieved by the addition of nano clay, silica fume and viscosity modifying agents (VMA), which are polluting, expensive or scarce. Finding other methods or materials to ...
