Abstract Scope |
During this investigation, the effect of fly ash as an additive or substitute for Portland cement on the initial absorption of concrete blocks (Vibro-compacted) is reported. For comparison, a standard specimen was manufactured with Portland cement without any substitution or addition of fly ash, this standard with an initial absorption coefficient of 24.2 g/(cm2 x min. 5), was compared with four specimens with a replacement or addition of fly ash. With this reference parameter, they were compared with the modified specimens, the first 15% of fly ash was added, reaching an initial absorption coefficient of 26.1 g/(cm2 x min.5) to the last three Portland cement was partially replaced in 15, 30 and 50% by fly ash with an initial absorption coefficient of 17.0, 19.5 and 22.6 g/(cm2 x min.5) respectively. The physical tests were carried out under the ONNCCE regulations. |
