Building materials

A method of making a cementitious mixture for building materials comprising obtaining a cementitious mixture comprising a calcium compound and ordinary Portland cement (OPC) and optionally supplementary cementitious material (SCM), and mixing the cementitious mixture, wherein the dosage of the calcium compound is about 3.1% to about 35% of the total binder content of the cementitious mixture.

A method of making a concrete mixture for building materials comprising:

• (a) obtaining a cementitious mixture comprising a calcium compound, ordinary Portland cement (OPC), fine aggregates, and coarse aggregates, and optionally supplementary cementitious material (SCM), wherein the dosage of the calcium compound is about 6.5% to about 15% of the total binder content of the cementitious mixture;
• and
• (b) adding water to the cementitious mixture.
