Cementing agents are materials used to bind particles together, creating a solid structure. They are commonly used in construction and manufacturing processes, where they help to form strong connections between different components. Examples of cementing agents include Portland cement, lime, and gypsum, which are essential in making concrete and mortar. In addition to construction, cementing agents are also utilized in various industries, such as oil and gas, where they help seal wells and prevent leaks. These agents play a crucial role in ensuring the durability and stability of structures and materials in diverse applications.
