Portland Cement

Portland cement is a common type of hydraulic cement made by grinding clinker—created from limestone, clay, and other materials fired at high temperatures—into a fine powder. When mixed with water, it forms a paste that hardens over time, binding other materials like sand and gravel to produce concrete. It is called "Portland" because early architects thought its color resembled Portland stone. Portland cement is essential in construction for building structures, roads, bridges, and various infrastructure projects due to its durability, strength, and ability to set and harden underwater.
