Abstract

This study was made on the reaction between aggregate and cement paste in autoclaved concrete and its influence on compressive strenght. The specimens mixed with cement and various curshed minerals (149–74 μ) were autoclaved at 181°C for 1–168 hours. Quartz and feldspars (microcline, albite and anorthite) reacted to cement paste, whereas hornblende, augite and olivine did not react. The reaction rate of minerals were, in order, anorthite >quartz>microcline=albite. 11 A tobermorite was formed by the reaction between cement paste and quartz, and feldspars. Hydrogarnet was also formed by the reaction between cement paste and anorthite. The compresive strength of the specimens containing quartz and feldspars increased as the curing time was prolonged.

Résumé

Cette étude prote sur la réaction, entre la pâte de ciment et les granulats et son influence sur la résistance à la compression du béton. Un mélange de ciment et de minéraux concassés a été traité à 181 degrés pendant 1 à 168 heures. Quartz et feldspaths (microcline, albite et anorthite) réagissent avec la pâte de ciment, la hornblende, l'augite et l'olivine ne réagissent pas. De la tobermorite a été formée par réaction entre le ciment, le quartz, et les feldspaths. De l'hydrogrenat s'est aussi formé par réaction entre le ciment et l'anorthite. L'examen de mélanges à quartz et feldspaths a montré une augmentation de la résistance en fonction du temps.
