Sustainable brick composition and method of preparation thereof

Abstract

A method of brick production includes mixing an uncalcined gypsum powder and a quartz material to form a mixture, mixing the mixture with water to form a composition, cold sintering the composition in a mold at a pressure of 50 to 450 megapascal (MPa) at room temperature for 20 to 40 minutes (min), and drying the cold sintered compositions for 5 to 10 days at a maximum temperature of 50 degrees Celsius (° C.) in a sealed container to form a brick. The quartz material is selected from a group consisting of a quartz sand and a quartz powder. A weight ratio of the uncalcined gypsum powder to the quartz material is from 5:95 to 95:5. A weight ratio of the water to the mixture is from 0.01:1 to 0.15:1.
