Over the past decade, 3D printing in construction industry has received worldwide attention and developed rapidly. The research development of cement concrete products also become quite well-established over years, while other sustainable materials receive considerably lower comparison. This study aims to investigate influence two most commonly used cementitious i.e., silica fume limestone powder, on printability, thermal mechanical properties fly ash–Portland blends. Ternary blends...
Large-scale 3D printed concrete structures with lattice infill will result in lightweight components high mass-specific strength, and faster fabrication, compared to conventional casting methods. However, the effect of different patterns on mechanical performance is still not addressed clearly many scientific publications. This study investigates bending 3D-printed beams four such as lattice, triangular, lattice-triangular, sinusoidal tested vertical (layer deposition direction) transverse...
Abstract The influence of the partial / full replacement fine aggregates with granulated blast furnace slag (GBS) and its effect on mechanical strength durability properties (acid attack) high-performance concrete grade (M60) had been studied in present work. mix designed such a way that one group natural sand another manufactured (Quarry dust). Each consisted five sub-groups, having 0%, 30%, 50%, 80% 100% GBS content. Other pozzolanic materials as fly ash silica fume were also employed to...
Abstract The objective of this study is to find the optimum percentage replacement cement with nano-silica in a concrete mix improve structural performance Concrete Filled Steel Tube (CFST) stub circular column under axial compressive load. CFST columns cross-sectional area conventional (without nS) and blended (with nS-CFST) had been experimentally numerically studied. amorphous silica major component cementitious materials, it reacts calcium hydroxide, which comprised silicate hydration....
