The ever growing concerns over global warming and other detrimental ecological changes have spurred the research and development of new kinds of cementitious materials produced from nonconventional resources. The reason is that the production of 1 ton of hydraulic cement will generate about 900 kg of carbon dioxide and consume about 5 billion joules of electrical power and fuel energy.

Talc is widely used as reinforcing filler in several industrial products such as paper, paints, rubbers, polymers, ceramics, and refractory materials.

The composition of talc makes it a potential raw material in cement formulation since magnesium can beneficially interact with phosphate to give cementitious material, as in phosphate-magnesia cements
