Abstract
Prezenta inventie se refera la un liant hidraulic pe baza de ciment si un agent de lichefiere. Liantul, conform inventiei, este constituit din ciment putzolanic, Portland sau ciment cu adaos de zgura sau cenusa, 0,1...1% un agent de lichefiere ales dintre un produs de condensare al acidului beta-naftalinsulfonic cu formaldehida, lignosulfonat de claciu si gluconat de sodiu, precum si 0,1...10% apa, procentelefiind exprimate în greutate si raportate la 100 parti ciment, care, în scopul îmbunatatirii rezistentei cimentului sau betonului obtinut din acest liant hidraulic, se trateaza cimentul înainte de amestecarea componentilor cu 0,1...10% în greutate apa.The present invention relates to a cement-based hydraulic binder and a liquefaction agent. According to the invention, the binder is constituted of putzolanic cement, Portland or cement with added slag or ash, 0.1 ... 1% of a liquefaction agent selected from a formaldehyde beta-naphthalenesulfonic acid condensate, coconut lignosulfonate and sodium gluconate as well as 0.1 ... 10% water, the percentages being expressed by weight and per 100 parts of cement, which, in order to improve the strength of cement or concrete obtained from this hydraulic binder, treats the cement before mixing the components with 0.1-10% by weight of water.
