Mineral Admixtures : The Key To High Strength Concrete

“…The explanation for this may be that the pozzolanic reaction took relatively longer time to show effect on strength; while, in the same time, the amount of cement was reduced by the replacement percentage of SF. The flexure strength was found to be affected by the replacement level of SF in the same manner as the compressive strength as shown in Table (4). Also it was found that the static modulus of elasticity increased compared to the control mix up to 15% replacement level; subsequently it decreased.…”

“…At 3-months age, the compressive strength for the 15% SF mix was markedly higher than that of the control mix. From Table (4), it is clear that there is a moderate drop in the early strength up to 7 days compared with the control mix. The explanation for this may be that the pozzolanic reaction took relatively longer time to show effect on strength; while, in the same time, the amount of cement was reduced by the replacement percentage of SF.…”

Caracterização fisico-mecanica de misturas de solo, cal e residuo "agua-de-cola"

“…O uso de resíduos é muito comum na Iugoslávia, onde cerca de 90% do cimento contém, na sua mistura, resíduos como escória, cinza volante e pozolanas. A prática tem confirmado, ao longo do tempo, o uso desses resíduos no cimento, tendo sido aperfeiçoadas propriedades como durabilidade química, redução do calor de hidratação, entre outras (POPOVIC et al, 1991).…”
