Title (EN) PROCESS FOR PRODUCING CALCIUM SILICATE MOLDINGS
(FR) PROCEDE DE PRODUCTION DE MOULAGES DE SILICATE DE CALCIUM
Abstract: front page image
(EN)Calcium silicate moldings with a low bulk density, high heat resistance, and excellent mechanical strength are produced by previously dispersing a lime material in water under specific conditions, adding a silicic acid material thereto, heating the mixture to cause a reaction and obtain an aqueous slurry containing calcium silicate hydrate and having specific properties, then dehydrating and molding this aqueous slurry and subjecting it to steam curing under pressure to crystallize calcium silicate hydrate.
(FR)Des moulages de silicate de calcium de faible densite, de grande resistance thermique, et presentant une excellente resistance mecanique sont produits par dispersion preliminaire de chaux dans de l"eau dans des conditions specifiques, addition d"un materiau d"acide silicique, chauffage du melange pour provoquer une reaction et obtenir une boue aqueuse contenant un hydrate de silicate de calcium et ayant des proprietes specifiques, puis deshydratation et moulage de cette boue aqueuse qui est soumise a une polymerisation a la vapeur sous pression pour cristalliser l"hydrate de silicate de calcium.
