β¦ Synopsis
The effects of two super water-reducing admixtures on the compressive strengths and elastic moduli of portland cement mortars containing fly ash were determined.
The results show that the effectiveness of the chemicals for improving the strengths of mixtures in which portland cement is partially replaced by fly ash decreases with an increase in the percentage of ash.
Increased strength can be nil or too low to justify the additional expense associated with the chemicals.
The mixtures did exhibit normal stress-strain relationships:
the elastic moduli were related to the ultimate compressive strengths in the usual manner.
The results are based on mixes with equal workabilities.
Fueron determinados los efectos de dos mixturas del tipo 'super reducidos por agua' sobre la solidez compresiva y los m6dulos el~sticos de morteros de cemento 'portland' que contienen 'fly ash'. Los resultados muestran que la eficaz de los qu{micos usados para aumentar la foraleza de mezclas en las cuales el cemento portland est~ parcialmente reemplazado por 'fly ash' disminuye seg~n el aumento en el contenido de 'fly ash'. O no hay solidez aumentado o el aumento puedo ser demasiado peque~o para justificar los gastos adicionales associados con los qufmicos.
Las mixturas manifestaron los parentescos normales para el esfuerzo y la tension: los m~dulos el~sticos exhibieron relaciones normales con la m~xima solidez compresiva.
Los resultados est~n basados sobre mixturas con consistencias iguales.
