Abstract
A floor topping, mortar and grout which include ferrosilicon in particle form. The ferrosilicon increases the wear resistance and impact strength of the topping, mortar or grout without the oxidation or discoloration normally attributable to materials which include iron borings. In addition, the ferrosilicon increases the light reflectivity of the topping material. A method of hardening and rendering wear resistant a concrete structure such as a floor comprising the placement of a mixture of Portland cement and particles of ferrosilicon material at the surface of the structure and thereafter troweling the mixture to a smooth surface.
