Highlights Functional gradation of concrete in structural elements can mitigate CO2 emissions. Fresh state deviations occur in wet cast horizontally layered multiple mix elements. Mix density, workability and layer sequence influence the layer profiles. Compatible mix combinations to achieve horizontal layers are identifiable.
Abstract Functionally graded concrete, where multiple mixes are layered in structural elements, is a promising technology for minimising cement use. However, a challenge when fabricating wet-on-wet graded concrete is the control of the fresh state deformations of multiple mixes cast into the same mould. Horizontally cast elements with two different concrete mix layers were investigated to ascertain the influence of mix density, workability and layer sequence on the intended material placement. Horizontal layers were achievable unless the workability of the top layer was much stiffer than that of the bottom, or the top layer was denser and both mixes were fluid. The findings underpin opportunities for the exploitation of lower carbon materials and cement efficiency.
