Diversifying two-stage mixing approach (TSMA) for recycled aggregate concrete: TSMAs and TSMAsc (2008, background): “Addition of silica fume generally results in improved performance of concrete [67, 68, 50, 69, 52, 56, 70, 71, 27, 47]; improvements on strength and rigidity have been recorded for TSMAs and TSMAsc.”
Formulation of elastic modulus of concrete using linear genetic programming (2010, methodology): “An experimental database, including previously published test results [22, 24-27 ], was utilized to develop the LGP-based Table 1. Parameter settings for the LGP algorithm.”
Mechanical and durability properties of high-strength concrete containing steel and polypropylene fibers (2015, background): “Additionally, it is well understood that the use of supplementary cementitious materials such as silica fume (SF), ground granulated blast-furnace slag (GGBS), and fly ash (FA) as part of binders is required for production of high strength concretes [9,10].”
The effects of silica fume and polypropylene fibers on the impact resistance and mechanical properties of concrete (2010, background): “It is well understood that silica fume, due to high pozzolanic activity, is inevitable material when producing high strength concrete; however, it causes the concrete to have a more brittle structure [4–5].”
