Experimental investigation on the use of fly ash for lightweight precast structural elements

Materials and Structures volume 29, pages 632–638 (1996)Cite this article

Abstract

The possibility of a partial or complete substitution of traditional aggregates in lightweight concretes with those made of fly ash is investigated in this paper. For this purpose, a survey of the literature on the desirable mechanical properties is conducted and extensive experiments are carried out. These experiments show that this substitution is perfectly feasible. It is also desirable from the standpoint of the policy of reusing industrial waste.

Résumé

Dans cet article on examine la possibilité de substitution partielle ou complète de granulats de cendres volantes aux granulats traditionnels en béton léger. À cet effet, on a passé en revue la littérature sur les qualités mécaniques voulues et on a effectué une vaste étude expérimentale. Ces essais montrent qu'une telle substitution est parfaitement faisable. Elle est également souhaitable au sein de la politique de recyclage des déchets industriels.
