Development of Variants of High-Performance Self-Compacting Concrete with Improved Resistance to the Attack of Sulfates

This paper presents experimental and analytical work of which the main objective was to support introduction a new technology for production sewer pipes. In this technology, pipes produced consist two differently parts. The direct part uses conventional vibro press compacted concrete. curved part, on other hand, self-compacting concrete is used. cooperating company, Prefa Brno a.s., defined possible negative effects task research team now author’s propose procedure development suitable variants subsequently design methodology verify their durability in aqueous environments containing sulfates. To increase efficiency development, model mortar method used work. That is, instead original concrete, derived from it tested. principle derivation mortars are described paper. total, eight were tested, at least three them fulfilled requirements. An optional but beneficial carried out practical application time-anchored-triangles-of-cracking graphical developed during research. quickly compare degree attack different silicate composites tested common bath inducing type III corrosion.
