Abstract
The hydrothermal formation of novel calcium silicate hydrates of compo sitions 5CaO . 2SiO(2). CaCl2. 4H(2)O, 5CaO . 2SiO(2). CaCl2. 2H(2)O a nd 4CaO . 2SiO(2). CaCl2. H2O from Ca3SiO5 and mixtures of CaO and SiO 2, respectively, in presence of calciumchloride at 200 degrees-350 deg rees C is described. From molybdate-reaction, Si-29 MASNMR, DTA and TG measurements it is concluded that these compounds are based on disili cate anions and are to be interpreted as calcium hydroxide disilicate chlorides.
