Abstract

This study systematically explores the rheological properties and printability of 3D printed manufactured sand concrete (3DPMSC), aiming to optimize the use of manufactured sand in 3D printed concrete (3DPC). The effects of water-binder ratio (W/B), superplasticizer (PCE) dosage, and cellulose ether (HPMC) content on the yield stress, plastic viscosity, and thixotropy of concrete were comprehensively analyzed through rheological and printing experiments. A secondary mixing process based on the cement-coated sand method, combined with a gradient PCE incorporation technique, was proposed to effectively mitigate the time-dependent rheological degradation of manufactured sand concrete. The results showed that a low W/B significantly enhanced the structural stability and thixotropy of the concrete while reducing its flowability. HPMC enhanced buildability by strengthening the particle network structure, and an appropriate dosage of PCE achieved a dynamic balance between shear thinning and thixotropic recovery, optimizing the printing quality. A material optimization design framework specifically for 3DPMSC is ultimately established, offering theoretical and practical guidance for sustainable use of manufactured sand in construction.
