Abstract
The enormous use of cement in construction leads to an effect on the environment. For 1 ton of cement production, nearly 1 ton of CO2 is released into the atmosphere. The production of Portland cement reached about 90 million tons globally in 2021(U.S. Geological Survey, 2022). To reduce the content of cement, various supplementary cementitious materials were used. Amongst supplementary cementitious materials (SCM), the usage of agro-waste ash appears as an exciting solution. Tobacco waste ash is one material that is suitable to replace with cement. Nearly per year, 1723.87 tons of tobacco waste were produced. In this investigation, tobacco waste ash is partially replaced by 5%, 10%, and 15% by weight of cement. The mechanical and durability properties include compressive strength (CS), split tensile strength (STS), and flexural strength (FS) were tested and compared with OPC concrete. It is concluded that mix containing 10% TWA exhibited higher strengths than compared to OPC concrete.
