Proportioning of green mortar by using different cementitious materials

Abstract

Pozzolanic materials are used extensively at the present time due to their availability in large quantities, especially materials that are considered waste from construction works and industrial waste. In this research, various pozzolanic materials were used, such as glass powder; ceramic powder, and brick powder, seven mortar mixes (M, M1, M2, M3, M4, M5 and M6). This research has been prepared and focuses on the impact of using these materials in mortars as cement replacement. M1, M2, M3 The cement was replaced as 30, 35, 40% by glass powder and ceramic powder (10% glass with 20, 25 and 30% ceramic powder) by weight of cement. M4, M5, M6 was replaced as 30, 35, 40% by glass powder and brick powder (10% glass with 20, 25, 30% brick powder) the cement by weight. The specimens were cast in a cube of 50 x 50 x 50 mm and the water curing regime was applied until the testing age. The fineness of the powder used in glass, ceramics and bricks is less than 45μm. Changes in compressive intensity for both samples have been examined. The optimal replacement that provided the better strength was found to be 40 percent replacement (10% glass with 30% brick powder).
