Abstract
A method of preparing a snow and ice control composition to improve traction on ice and snow covered surfaces. The composition comprises coal ash, binder, a melting depressant and enough water to form a dough-like mixture with said mixture pelletized by extrusion through a die and cured to form particles ranging in size from 1/16 th to 11/2 inches. The resulting said pellets have excellent strength and can be formulated to be environmentally acceptable.
Claims6
A method of preparing a snow and ice control composition comprising the steps of combining a coal ash material, a salt and/or organic material for lowering the melting point of snow or ice, a silicate finding agent having a silica/alkali metal oxide ratio of 3.50 to 2.00 and enough water to form a dough-like workable mixture;
- pelletizing said mixture and heating said pellets to form shaped particles having excellent crush resistance.
