Abstract
Fly ash-lime-phosphogypsum (FaL-G) bricks are one of the best alternatives to the conventional burnt clay bricks. This paper gives the results of an experimental investigation in which the compressive strength, water absorption, density and durability of Fly ash-lime-phosphogypsum (FaL-G) bricks were investigated by using varying quantities of fly ash, lime and calcined phosphogypsum. The properties of Fly ash-lime-phosphogypsum (FaL-G) bricks are compared with those of the ordinary burnt clay bricks. The results indicate that these bricks are lighter in weight, durable in aggressive environments and have sufficient strength for their use in building construction.
Résumé
Les briques à base de cendres volantes-chaux-phosphogypse (FaL-G) sont une des meilleures alternatives aux briques conventionnelles en terre cuite. Cet article présente les résultats d'une étude expérimentale dans laquelle la résistance à la compression, l'absorption d'eau, la densité et la durabilité des briques en FaL-G ont été examinées en utilisant différentes quantités de cendres volantes, de chaux et de phosphogypse calciné. Les propriétés des briques en FaL-G sont comparées avec celles des briques ordinaires en terre cuite. Les résultats obtenus indiquent que ces briques sont plus légères, durables dans des environnement agressifs et assez résistantes pour être utilisées dans la construction.
