Explanation/Annotation:Prevents the freezing of concrete mix in transit, brick-work and densification, as well as before the beginning of active heat treatment.
Detailed model description:The Ñ-3Ð2 addition provides:
forced the strength increase in case of active heat treatment in initial the maturity interval, at the expense of what the achievement time ðàñïàëóáíîé
the plasticization of concrete mix without additional application of chemical agents has been shrinking;
possibility of joint use on the other âîäî-ðàñòâîðèìûìè additions;
regions and conditions of application:
"Ñ-3Ð2" allows to work with concretes and solutions in case of mean daily temperature to - 15 degree. With
the Ñ-3Ð2 addition is introduced at concrete (solution) the mixture with gauged water
recommended the percent of addition agent insertion at different temperatures:
to - 5 degree. With - 1%; to - 10 degree. With - 1, 5%; to - 15 degree. With - 2%
%-ìàññîâàÿ share of addition on a dry basis from cement mass.
note: the maximum quantity of addition "Ñ-3Ð2" must not exceed 4 , 0% on a dry basis, in relation to cement mass. |
