Webb1 juli 2014 · The present work aims at quantitatively evaluating the cohesion (post-peak) strength of a common concrete and a micro-concrete and proposing a modelling of their softening behaviour. To achieve this goal, several spalling tests have been performed to damage without breaking the specimen. WebbCement is the most produced material in the world. A major player in greenhouse gas emissions, it is the main binding agent in concrete, providing a cohesive strength that …
WebbThe cohesiveness of concrete in the fresh state, which is crucial for printing, can be improved by using non-structural fibers such as polypropylene or basalt. The use of fiber reinforcement in 3D printing creates a much-needed segway into the fields of ultra-high performance concretes with enhanced strengths and durability , crucial in aesthetic … Webb1 okt. 2024 · Viscosity-modifying admixture (VMA) can be added as an alternative to adding more cement powder or supplementary cementitious materials to improve the cohesion and stability of the LCC matrix. This study investigated the role of VMA addition in increasing stability in low water to cement ratio (w/c) mortar with an excessive …
