Abstract

L'invention concerne des formulations composites de fibrociment destinée à former des articles de construction en fibrociment durci. Certains modes de réalisation comprennent entre 10 % et 40 % en poids sec d'un matériau cimentaire comprenant au moins 5 % de calcaire, entre 0,5 % et 20 % en poids sec de sol calciné comprenant de l'argile calcinée et une charge, entre 30 % et 70 % en poids sec de silice, et entre 1 % et 15 % en poids sec de fibres de cellulose. L'invention concerne également des articles de construction en fibrociment formés à partir des formulations décrites, par exemple, par l'intermédiaire du procédé de Hatschek. Les articles de construction en fibrociment peuvent être durcis en autoclave dans un récipient sous pression de vapeur. Des combinaisons synergiques des composants de formulations composites de fibrociment selon l'invention réagissent les unes avec les autres pendant l'autoclavage pour former des phases durables qui présentent une résistance, une durabilité et des caractéristiques de stabilité dimensionnelle étonnamment élevées dans des articles de construction en fibrociment durcis.
