An evaluation of the compressive and flexural clevernesss obtained from different curing conditions is made. The evolution of phases presented was in like manner studied from XRD spectra. The relationship between the set of ultrasonic university extension velocity. UPV. (Yl-axis) and compressive strengths (Y-?-axis) versus w/c ratios for CAC mortars, cured at 5°C. 20°C and 60°C respectively. have also been obtained, at a curing age of 28 days. The great similarity of curves enables us to establish the hypothesis that it is potential to use a non destructive test as an data-based determination of compressive strength for CAC mortars with the same proportions of aggregates/ cements/water as those utilize in the test. Abrams retrieve was applied in differentiate to full point the earth of this model in the CAC mortars studied. The percentage of variability of the uncertain receipt (Rc). obtained in our regression models is highly sat isfactory. 0 1997 Else\Yer Scierwe Ltd u! nveiling Although the represent of...If you want to get a full essay, order it on our website: OrderCustomPaper.com
