This invention relates to a mixture of construction material composition, which is mainly used by the construction sector and has high strength, water-tightness and low-cost features. In comparison with the chemical substances, the predominating existence of the anhydrite material in granulated and natural form within the mixture of construction material composition enables low-cost production of the mixture and the physical structure of the anhydrite material and its granulated form ensure high strength on the application area. As the water absorption capacity of the anhydrite material within the mixture is low, it has high water-tightness. |
