Originální abstrakt

This study describes findings of monitoring concerning the sulphate/acid resistance of concrete made from various volumes of fine/coarse recycled concrete aggregates. Corroding medium used: Na2SO4 concentrated solution to 10,000 mg/l, or diluted HCl with pH 3 in some cases. Test samples have been exposed to this medium for a period of 18 months. Natural aggregates have been replaced with recycled concrete ones in various proportions; monitoring findings show that there are concretes resistant to sulphate/acid aggressive environment as follows: (i) reference concrete (etalon); (ii) concrete made from fine (100 % natural) aggregate and coarse aggregate (50 % natural, 50 % recycled aggregate); (iii) concrete made from fine (100 % natural) aggregate and coarse aggregate (100 % recycled aggregate); (iv) concrete made from fine (50 % natural, 50 % recycled aggregate) aggregate and coarse aggregate (100 % natural). Parameters of other concretes under monitoring hit their maximum levels after 6 to 12 months of exposure being followed by a subsequent decrease; that is why they are not resistant to said aggressive environment
