Talc as raw material for cementitious products formulation

The chemical analysis of the used talc is given in Table 1.For the ideal talc formulation (Mg 3 Si 4 O 10 (OH) 2), the theoretical content of equivalent magnesium oxide is 31.9% and silica is 63.4%.Hence, the content in magnesia (32.08%, MgO) and silica (51.71%, SiO 2) is consistent with the magnesium silicate nature of the talc.However, the …
