Cement

Cement is a key ingredient in concrete, used widely in construction to create strong, durable structures like buildings, bridges, and roads. It acts as a binding agent when mixed with water, sand, and aggregates, hardening to create a solid, stone-like material. Here’s a closer look at cement, its types, production process, and applications. Key Components of Cement 1. Limestone (Calcium Carbonate): The primary ingredient, making up about 60-70% of cement, provides calcium oxide when heated. 2. Clay or Shale: Provides silica, alumina, and iron oxides, which contribute to the strength and durability of cement. 3. Other Additives: Gypsum, a small percentage added during the grinding process, controls the setting time of cement. Cement is an essential building material that underpins much of our infrastructure, with numerous applications and benefits. However, its production is energy-intensive and contributes to CO₂ emissions, prompting innovation and research into sustainable alternatives.
