Abstract

Předpokládané řešení se týká technologie cementů, zejména výroby hlinitanových cementů a může být realizován v řadě průmyslových odvětví, např. ve strojírenství. Cílem tohoto řeSení je sníženi velikosti deformací a zvýšení pevnosti cementového kameniva. Vytčeného cíle je dosaženo tím, že v pojivu, obsahujícím kalciumhlinitanový materiál a přísady, byl pro kalciumhlinitanový materiál zvolen částečně dehydrovaný hydrogranét vápnika s obecným vzorcem SCaO.A^Oj.xSiOg.yHgO, kde x = 0,01 až 0,40; y = 0,65 až 1,75, a pro přísady vápno, karbonáty a karbohlinitany kalcia v následujícím poměru složek podle váhy v částečně dehydrovaný hydrogranét vápníku s obecným vzorcem 3CaO.Al2O3.SiO2.yH2O, x = O,01 až 0,40; y = 0,65 až 1 ,75 vápno karbonáty vápníku karbohlinitany vápníku kde 25 až 97 0,5 až 10 1 až 50 1 až 30The proposed solution relates to cement technology, in particular the production of alumina cements, and can be implemented in a number of industrial sectors, e.g. in mechanical engineering. The aim of this solution is to reduce the size of deformations and increase the strength of cement aggregates. The set goal is achieved by the fact that in the binder containing calcium aluminate material and additives, a partially dehydrated calcium hydrogranite with the general formula SCaO.Al2O3.xSiOg.yHgO was selected for the calcium aluminate material, where x = 0.01 to 0.40; y = 0.65 to 1.75, and for the additives lime, carbonates and calcium carboaluminates in the following ratio of components by weight in a partially dehydrated calcium hydrogranite with the general formula 3CaO.Al2O3.SiO2.yH2O, x = 0.01 to 0.40; y = 0.65 to 1.75 lime calcium carbonates calcium carboaluminates where 25 to 97 0.5 to 10 1 to 50 1 to 30
