Research of Frost Resistance of Tuff-Containing Portland Cement

Abstract

Results of a study of frost resistance up to 150 cycles of freezing and thawing of Portland cement and pozzolanic Portland cements obtained on the basis of these Portland cement clinkers with various dosages burnt tuffite, gliège , showed that up to 30% tuffite to Portland cements with different mineralogical composition has a positive effect, increasing their grade in standard samples.
