Abstract:This work aims to investigate the influence of Cr 3+ , Co 2+ and Cu 2+ on the formation of calcium silicates hydrates in CaO-SiO 2-Al 2 O 3-H 2 O system under hydrothermal conditions. The dry primary mixture with the molar ratio CaO/(SiO 2 + Al 2 O 3) = 1.5 and Al 2 O 3 /(Al 2 O 3 + SiO 2) = 0.05 was mixed with heavy metal nitrate solutions (metal ions concentration-10 g/l) to reach the water/solid ratio of the suspension equal to 10.0. The hydrothermal synthesis was carried out in unstirred suspensions, under… Show more
“…Previously it has been shown that hydrothermal C -S -H phases may incorporate heavy metal elements [58]. That Cr and V are effectively incorporated in the reaction products that formed during autoclaving is also proven by the composition of the PARC reaction product (Table 5).…”
