Hydration of portland cement paste with addition of low quantity of hydrosodalite

Abstract

There are same investigations of hydration of zeolites in cement and concrete matrix and as admixtures in advanced building materials. Hydrosodalite as a hydraulic admixture, as well as its influence on the hydration processes and microstructure of hardened cement paste was used. The references did not contain any data of the use of low quantity (1-3%) of hydrosodalite in concrete technologies.
