Special hardening features of a magnesia binder

The article cites the results of investigations into the effect of the activity of a magnesia binder and of the temperer (MgCl_2 solution) concentration on the parameters of the hardening magnesia stone.
It is shown that the durability and crack resistance of cement stone is determined by 5MgO·MgCl_2·13H20 mineral whose content can be adjusted by changing the temperer concentration and burning temperature of the binder.
