A new pozzolanic material basically conformed of microsilica with a minimum of silica of 85% in its composition is described, where the silica of the material is conformed mainly of cristobalite and tridimite. Unlike microsilica conformed basically of quartz, the microsilica of the invention exhibits greater pozzolanic indexes and provides improved characteristics of durability to concrete cements and in smaller proportions. Also simple and low consumption energy methods for obtaining the pozzolanic material of the invention are described.
L'invention concerne une nouvelle matière pouzzolanique fondamentalement constituée de microsilice avec un minimum de 85 % de silice dans sa composition, la silice de cette matière est principalement constituée de cristobalite et tridimite. A la différence de la microsilice fabriquée fondamentalement de quartz, la microsilice de l'invention présente des indices pouzzolaniques supérieurs et fournit des caractéristiques améliorées de durabilité afin de former des ciments et en proportion plus petite. L'invention concerne également des procédés de faible consommation d'énergie simple en vue d'obtenir la matière pozzolanique de l'invention.
