Abstract
A hydrophobic admixture may include titanium dioxide at about 1-16.5 weight % (wt %) of the hydrophobic admixture. The hydrophobic admixture can include a carbon allotrope at about 1-38.5 wt % of the hydrophobic admixture. The hydrophobic admixture may include calcium salt at about 25-82.5 wt % of the hydrophobic admixture. The hydrophobic admixture may include calcium stearate at about 15-27.5 wt % of the hydrophobic admixture. The hydrophobic admixture may include magnesium carbonate at about 0-11 wt % of the hydrophobic admixture.

A hydrophobic admixture, comprising:
- titanium dioxide at about 1-16.5 weight % (wt %) of the hydrophobic admixture;
- carbon allotrope at about 1-38.5 wt % of the hydrophobic admixture;
- calcium salt at about 25-82.5 wt % of the hydrophobic admixture;
- calcium stearate at about 15-27.5 wt % of the hydrophobic admixture;
- and
- magnesium carbonate at about 0-11 wt % of the hydrophobic admixture.
A method, comprising:
- forming a first mixture comprising titanium dioxide and graphite;
- blending the first mixture to form a first blend;
- heating the first blend;
- forming a second mixture comprising the first blend, calcium carbonate, and magnesium carbonate;
- blending the second mixture to form a second blend;
- heating the second blend;
- and
- mixing the second blend and calcium stearate to form a hydrophobic admixture.
A hydrophobic building material, comprising:
- a binder;
- an aggregate;
- a water portion;
