Method for the Production of Portland Cement Composition with Low Embodied Energy and Carbon for Abrasion Resistant Concrete and Mortar

A cement composition comprising:

• Portland cement;
• and
• a mineral additive derived from a hard mineral raw material;
• the mineral additive being (i) substantially chemically inert in an aqueous Portland cement environment, (ii) substantially non-hydraulic, and (iii) substantially non-pozzolanic;
• the mineral additive having a Mohs hardness of 7.0 or more;
• and
• the mineral additive comprising a particulate material having a median particle size ranging from 4 to 800 microns.

A method for producing a Portland cement composition from mineral raw materials comprising:

• comminuting the mineral raw material to obtain a mineral additive such that a median particle size of the mineral additive ranges from 4 to 800 microns;
• adding the mineral raw material to Portland cement prior to comminution or adding the mineral additive to Portland cement after comminution to form the Portland cement composition such that a mass of the mineral additive within the cement composition is 5 to 50% of a total mass of the Portland cement and the mineral additive in the cement composition;
• sourcing the mineral raw material prior to comminution from natural sources, industrial by-products or synthetic manufacturing such that:
• the mineral additive is (i) substantially chemically inert in an aqueous Portland cement environment, (ii) substantially non-hydraulic, and (iii) substantially non-pozzolanic;
• and
• the mineral additive has a Mohs hardness of 7.0 or more.
