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.
Claims15
In a particulate mixture for embedding into the unset upper surface of a concrete floor the improved mixture comprising
- Portland cement, and
- ferrosilicon particles having a silicon content of no more than 20%, and having a particle size range of 6 mm. to 200 mesh;

In a topping for floors and the like, the improved composition consisting essentially of
- acid resistant cement, and
- ferrosilicon particles having a silicon content of no more than 20%;
- said ferrosilicon particles being of sufficiently coarse mesh that essentially no chemical reaction is caused between said ferrosilicon particles and said acid resistant cement.
In a topping for floors and the like, the improved mixture comprising
- acid resistant cement, and
- ferrosilicon particles having a silicon content of no more than 20%, and a particle size range of 6 mm. to 200 mesh;
