Abstract

Prezenta inventie se refera la un procedeu de obtinere a unui aditiv pentru paste de cimentare, prin amestecarea unei solutii de NaOH cu reziduuri de tartrati având continuturi de 34% substante solubile si 66% substante insolubile, la temperatura de 90 degree C,se realizeaza un produs eficient si constant, care manifesta efecte de întârziere a prizei pastelor de ciment cu densitati < 1,9 kgf/dm3.The present invention relates to a process for obtaining a cement paste additive by mixing a NaOH solution with tartrate residues having 34% soluble substances content and 66% insoluble substances at a temperature of 90 ° C. efficient and constant product, which exhibits delaying effects of cement paste with density < 1.9 kgf / dm3.
