Special Concretes: Enhancement of Resistance to Aggressive Media Using Fly Ash and Admixtures Featuring Pozzuolana Characteristics

Popis výsledku v původním jazyce

This paper presents findings of testing focused on resistance enhancement of special concretes (SCC, HPC, RPC) as well as common concrete (C) through application of secondary raw material (fly ash) and admixtures featuring pozzolana characteristics (metakaolin). The tests were aimed at examination, comparison, analyzing and evaluation of admixture of fly ash and/or meta kaolin respectively as to their influence on above mentioned special concretes exposed to various chemical aggressive media. Analyzedconcretes were stored in aggressive liquid media (SO42-, Cl-, engine lubrication oil), gaseous media (simulated concentration of CO2, SO2 under various relative humidity), along with reference samples in aqueous media as specified by appropriate standards. After 3, 6, 9 and 12 months, particular concretes passed through physico-mechanical and physico-chemical analyses i.e. tested were their physico-mechanical and physico-chemical properties, appearance, and condition after their exposure
