Abstract
Przedmiotem wynalazku jest zastosowanie sodowego szkła wodnego jako dodatku sterującego czasem wiązania mieszanki betonowej oraz sposób otrzymywania mieszanki betonowej o wydłużonym lub skróconym czasie początku wiązania, przy czym jako dodatek stosuje się sodowe szkło wodne z modułem 3,0 – 3,2 w ilości od 1 do 4% względem masy suchego cementu.The subject of the invention is the use of sodium water glass as an additive that controls the setting time of a concrete mix and a method of obtaining a concrete mix with an extended or shortened setting time, where sodium water glass with a module of 3.0 - 3.2 is used as an additive in an amount from 1 to 4% based on the weight of dry cement.
