CONCRETE MIX

摘要

FIELD: building practice; application of protective coatings onto structures exposed to attack by biologically aggressive media. SUBSTANCE: proposed concrete mix has following composition, wt.%: Portland cement 27.2- 38.6; sand 38.6-55.36; micronized silica 3.86-3.87; C-3 0.3-0.31; biocidal additive 1.16-1.18; glass fibres 1.16-1.93, water being balance. EFFECT: proposed mix is particularly useful in combatting aggressive biological agents. 1 tbli
