The emerging technology of 3D concrete printing enables faster construction, complex geometries, and reduced on-site injury risks. Despite its benefits, it still relies heavily on cement. Incorporating recycled aggregate ...
A incorporação de agregados reciclados (AR) em betões estruturais é uma via concreta para operacionalizar a economia circular na construção, reduzindo a extração de recursos naturais e o envio de resíduos de construção e ...
The Time Zero in cementitious mixtures marks the transition from a fluid suspension to a rigid structure, a critical phase for shrinkage analysis. This paper proposes a novel technique to measure Time Zero in cementitious ...
