A cementitious composition comprising a) cement (hereinafter referred to as component a); b) an admixture containing a polycarboxylate copolymer (the admixture hereinafter being referred to as component b); and c) a quick setting agent or accelerator (hereinafter referred to as component c).

ClO2 is produced efficiently by the redn. of NaClO3 in an aq. medium. The reaction is carried out at the b.pt. under reduced pressure. Pref. HClO3 and HCl react with consumption of Cl- and formation of HClO, which is reduced to Cl- by MeOH. If HClO is produced more quickly than it is consumed, it reacts with HCl to form Cl2. This hampers prodn. of ClO2 and also contaminates the prod.. Lower acidit...
