- (Contens №5 2020)
- ... Findings. With increasing short-term storage (up to 24 hours) of structured sand-sodium-silicate mixtures in air, their strength increases and crumbling decreases. With long-term storage – strength decreases and crumbling increases. Storage of prepared sand-sodium-silicate mixtures should be carried out in a hermetically sealed container using a portion of sodium hydroxide. For the first time, kinetics of sodium-silicate mixtures carbonization in a layer 20 µm thick has been established. Based on the experimental data, kinetic curves for sodium silicate solute in clad layer carbonization are constructed. The reasons of extremum on kinetic curves presence are considered. Analytical expression for dependence of structured sand-sodium-silicate mixture crushability on the time of their staying in air has been developed. It is established that, among technological additives in sodium silicate solute tested in the work, no additive prevents or slows down the process of dehydrated sodium silicate solute in clad layer carbonization. ...
