Abstract Elastic behavior is an important aspect of fresh cement‐based materials. In this paper, the elasticity development pure alite paste within 5 hours was monitored in situ by small amplitude oscillation shear. Isothermal microcalorimetry, X‐ray diffraction, scanning electronic microscopy, 1 H nuclear magnetic resonance, zeta potential measurements were used to investigate underlying mechanisms. It found that evolution storage modulus can be characterized three different stages. The...
Weak interlayer interface is a major drawback of three-dimensional (3D) printed cementitious materials technology. In this paper, the effect anionic polyacrylamide (APAM) with different dosages on workability, properties (i.e., durability, shear bond strength) and microstructure 3D cement mortar were studied. The relationship between workability regulated by APAM was analyzed. results showed that artifacts had good correlation fresh pastes. With increase content, plastic viscosity structural...
The mix proportioning of extrusion-based 3D-printed cementitious material should balance printability and hardened properties. This paper investigated the effects three key proportion parameters alkali-activated fly ash/slag (3D-AAFS) mortar, i.e., sand to binder (s/b) ratio, ash/ground granulated blast-furnace slag (FA/GGBS) silicate modulus (Ms) activator, on extrudability, buildability, interlayer strength, drying shrinkage. results showed that loss extrudability development buildability...
