The solution was again vigorously stirred and manganese precipitated as hydroxide by the slow addition of more of the caustic soda solution until the pH value of the liquor rose to 9. About 40 litres of the caustic soda solution were needed, and were added over a period of about 15 minutes.
(MgO concrete) is concrete with an additive of lightly burnt MgO powder. When MgO hydration takes place, the final product is magnesium hydroxide, Mg(OH) 2. Because Mg(OH) 2 has a larger volume than its constituents, MgO concrete is expansive. Concrete made with more typical expansive cements like ASTM C 8451 Types M, K, and S expand at early ages.
Manganese slag is a by-product of ferromanganese alloy manufacturing.
