Magnesium oxychloride cement compostions, products, and uses thereof, are provided by mixing a magnesium oxide com- position, a magnesium chloride brine solution, and aggregate particles. The cement compositions are adapted for use in repairing damaged concrete surfaces, casting both functional and decorative forms, and coating surfaces with stucco. The addition of a small amount of acid may be added to the cement composition to promote a mor e complete cementing reaction. The resulting ce- ment product exhibits substantially increased strength and water resistance. Brine from the Great Salt Lake is a preferable source of the magnesium chloride brine solution. Brine from the Great Salt Lake, which contains various mineral impurities, results in a cement composition substantially stronger than cement produced from a pure magnesium chloride brine solution.
