Publikováno v: Revista IBRACON de Estruturas e Materiais, Vol 16, Iss 5 (2023)
Abstract Wet packing methods evaluate the packing density of fine materials through the determination of the apparent density and voids content of pastes with different water to solids (w/s) ratios. Its goal is to estimate the minimum water demand to

Study of low-cement concrete mix-design through particle packing techniques
Autor: Nayara Soares Klein, Wellington Mazer, Carolina Londero
Publikováno v: Journal of Building Engineering. 42:103071
The cement production is responsible for about 7% of global emissions of carbon dioxide (CO 2 ) into the atmosphere. One way to mitigate this impact is through the consolidation of techniques involving the production of environmentally sustainable mi

Low-cement high-strength concrete with partial replacement of Portland cement with stone powder and silica fume designed by particle packing optimization
Autor: Nayara Soares Klein, M. Bianchini, H.F. Campos, J. Marques Filho
Publikováno v: Journal of Cleaner Production. 261:121228
Sustainability has become a major focus of the concrete industry, which is largely due to the CO2 emissions associated with Portland cement production. The process of crushing rocks to produce aggregates can also cause environmental damage since it g

Influence of the granular skeleton packing density on the static elastic modulus of conventional concretes
Autor: Nayara Soares Klein, Lauri Anderson Lenz, Wellington Mazer
Publikováno v: Construction and Building Materials. 242:118086
Particle packing methods are very useful for reducing the cement consumption of concrete mixtures and consequently the CO2 emissions associated with them. They usually also increase the solids concentration of the mixes, which fosters particle interl
