The process begins with the quarrying of raw materials as cement is made of a combination of calcium carbonate, silica, alumina, and iron ore. Conversely, these are extracted from key raw materials, including

cement.13 There are two primaryes in manufacturing clinkers: the dry and the wet. Most cement plants use the dry, which is more energy-efficient. In the wet, the raw materials are mixed with water to form a slurry, which is fed into a kiln. Fuel costs are greater in the wet
inclusion of fly ash in the concrete mix can improve the performance of concrete at elevated temperatures or its fire performance (Nadeem, Memon, Lo, 2014). Aside from fly ash, an another way to make concrete more sustainable is by substituting natural aggregates with less energy-intensive and sustainable materials, such as
Self-healing concrete. Xu Huang, Sakdirat Kaewunruen, in New Materials in Civil Engineering, 2020. 27.1.1 Background. Concrete is made by mixing cement, coarse and fine aggregate, water, and sometimes other substances. It is widely used for construction and has high compressive strength, high stiffness, and low cost [1].The obvious
