Large-scale 3D printing of ultra-high performance concrete,
In the present paper a new additive manufacturing processing route is introduced for ultra-high performance concrete. Interdisciplinary work involving materials science, computation, robotics, architecture and design re-sulted in the development of an innovative way of 3D printing cementitious materials. The 3D printing processHigh Performance Concrete Topic,01/05/2021· High-performance concrete (HPC) is concrete that has been designed to be more durable and, if necessary, stronger than conventional concrete. HPC mixtures are composed of essentially the same materials as conventional concrete mixtures, but the proportions are designed, or engineered, to provide the strength and durability needed for the structural and environmentalExperimental study of concrete made with granite and iron,,01/09/2016· Kala conducted tests on granite powder as a partial sand replacement in high performance concrete and showed the beneficial effects on its mechanical properties. Of all the six mixtures he considered, concrete with 25% of granite powder (GP25) was found to be superior to other percentages of granite powder concrete as well as conventional. Prabhu et al. studied the influence of Foundry SandPreparation of high performance foamed concrete from,,The titled high performance foamed concrete was developed from Portland cement, ultra fine granulated blast-furnace slag, pulverized fly ash and condensed silica fume by means of pre-foaming process.
