NTCC 2017: Long-Term Observation of the Resistance of Novel Hybrid Cement Exposed to Sulphate Solution

Abstract:

This work is aimed to investigate four-years impact of 5 % sodium sulphate solution on the mortar made of novel hybrid cement H-CEMENT, being prepared with maximal content of wastes and by-products and only 20 % wt. of Portland cement clinker, compared to that prepared with the reference CEM I 42.5 N (PC). H-CEMENT for its specific material composition does not meet the criteria for inclusion in the cement kinds reported in EN 197-1 but complies with all of the hygienic regulations and standards imposed on similar building materials.
