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).
Highlights
Pozzolanic materials have been used as building material, in particular for their effect on the improvement of concrete microstructure and durability. [1]Natural resource demand has risen dramatically, which puts tremendous strain on the ecosystem
The word" green cement" takes its place. It refers to the use of new materials that can partially substitute cement in concrete without reducing its mechanical properties and durability. It is a goal of replacing cement that needs to be done for sustainability. [2]Many researchers have studied different types of cementitious materials, Pitarch. et al.,2021, [3] Using 3 different types of ceramic waste: red clay bricks (RCB), ceramic tiles (CTW) and ceramic sanitary-ware (CSW), the pozzolanic activity of tiles, bricks and ceramic sanitary-ware was studied in eco-friendly Portland blended cements
Chen et . al, 2020, [6] The waste ceramic powder was studied as a pozzolanic supplementary cement filler for the development of sustainable building materials using a type of micro ceramic powder with an average size of up to 3.5 μm produced from ceramic waste and up to 40 percent cement was replaced to modify the microstructure and mechanical properties of the cement materials
Summary
Pozzolanic materials have been used as building material, in particular for their effect on the improvement of concrete microstructure and durability. [1]Natural resource demand has risen dramatically, which puts tremendous strain on the ecosystem. The word" green cement" takes its place It refers to the use of new materials that can partially substitute cement in concrete without reducing its mechanical properties and durability. Relative to OPC mortar, the maximum improvement in compressive and splitting tensile strength was obtained by replacing 40 percent of OPC with ceramic powder and 100 percent of the fine natural aggregate with fine aggregate waste ceramic. Al, 2020, [6] The waste ceramic powder was studied as a pozzolanic supplementary cement filler for the development of sustainable building materials using a type of micro ceramic powder with an average size of up to 3.5 μm produced from ceramic waste and up to 40 percent cement was replaced to modify the microstructure and mechanical properties of the cement materials. Glass powder has been partly substituted by 10 percent, 20 percent, 30 percent and 40 percent and has been compared with standard concrete for its compressive, tensile and flexural strength up to 60 days of age and demonstrates that the glass powder concrete effectively improves the compressive, tensile and flexural strength., when compared with conventional concrete
