Mixture of the Reaction Products during Hardening of the Water Glass Radiation-Protective Composites


Article Preview

The water glass can be used as a binder for the design of water-resistant radiation-protective building materials. In the present work the possibility of hardening of such materials by barium chloride is investigated. The chemical reactions which can take place during the structure forming and lead to the formation of barium hydrosilicates are presented. It is shown by means of X-ray phase analysis that formation of such hydrosilicates of composition BaO·SiO2·6Н2О, BaO·2SiO2·4Н2О, Ba2[SiO2(OH)2]2 and BaO·SiO2·Н2О actually occurs. The influence of the quantity of hardener to the chemical composition of the reaction products is examined. The effect of the reaction products to the water resistance of composite is studied. It is shown that water resistance can be increased in case of stochiometric quantity of barium chloride; in such case the primary product of reaction is BaO·2SiO2·4Н2О.
