Abstract
The present work evaluated the effects of incorporating high volumes of waste from the processing of ornamental stones as fillers in self-compacting micro-concretes, considering physical–chemical, mechanical, microstructural and eco-efficiency results. A particle packing method assisted in the mix designs, and the experimental program followed a central composite rotational statistical design. Response surfaces and desirability analyses showed that the residue has a good packing function, filler effect, heterogeneous nucleation and workability, in addition to being effective in reducing the embodied CO2, delivering matrices more eco-efficient for conventional mechanical strengths.
