The role of various aggregates on rheology of fresh 3D printing concrete

Popis výsledku v původním jazyce

The improvement of rheological properties of fresh 3D printing concrete by partial replacement of fine aggregate by fine recycled concrete was studied. The fineness and shape of the aggregate and sand content affects the rheological parameters of fresh mixture. Testing on rotational rheometer was carried out using coaxial cylinders. Testing was carried out in flow regime to evaluate shear and time-dependent rheological properties of fresh printing concrete. The role of packing density of various printing concrete mix designs on rheological parameters were discussed. Small addition of recycled concrete can improve rheological parameters of fresh printing concrete. The proper combination of recycled concrete and sand is the key in optimization of flow properties of 3D concrete.
