Abstract
The present study was undertaken with a view to an accelerated testing method which would permit prediction of standard compressive strength of cement within 24 hours at most. Test specimens were 11.3×11.3 mm dry cement cylindrical compacts (average porosity 22.6% and 26.8%) cured, for 24 hours at 21°C or for 3 hours at 100°C, in distilled water or in a super-satured lime solution. A linear relation was established between the cement and the compact strength for all the four curing regimes studied. The 24 hour curing in distilled water at 21°C, however, was considered preferable, permitting strength prediction within ±11.5 kg per sq.cm at 95% confidence level. Further study on cements with a wider range of properties will be needed, however, before the method can be recommended as a substitute for current standard procedures.
Résumé
On a entrepris cette étude en vue d'obtenir une méthode d'essais accélérés qui permettrait de prédire dans un délai de24 heures au plus la résistance normale en compression du ciment. Les éprouvettes étaient des agglomérés de ciment sec (porosité moyenne: 22,6 et 22,−%) conservés24 heures à21°C ou3 heures à100°C, dans de l'eau distillée ou dans une solution de chaux sursaturée. On a établi une relation linéaire entre le ciment et la résistance à l'état compacté pour les4 régimes de conservation étudiés. Il est apparu que la conservation de24 heures en eau distillée à21°C était préférable, permettant de prédire la résistance à+ou −11,5 kg/cm2 près pour une crédibilité de 95%. D'autres études sur les ciments portant sur une gamme plus large de propriétés seraient cependant nécessaires avant que la méthode puisse être recommandée comme un substitut des méthodes normales ordinaires.
