ABSTRACT:
A method of producing freeze-thaw resistant cementitious porous materials, such as concrete, mortar, stucco, in which up to about 30% by weight of the cement of a porous particulate material is mixed into the material. The particulate material may be finely divided fired clay, brick, diatomaceous earth or other mineral particles having a size range of 20-50 Tyler mesh, a total porosity of at least 30% and a pore size in the range 0.05 to 3.0 microns.
