Composition of cement Introduction Portland cement gets its strength from chemical reactions between the cement and water The process is known as hydrationThis is a complex process that is best understood by first understanding the chemical composition of cement
Portland cement is the basic ingredient of concrete Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients
The water-cement ratio is the weight of the mixing water divided by the weight of the cement High-quality concrete is produced by lowering the water-cement ratio as much as possible without sacrificing the workability of fresh concrete, allowing it to be properly placed, consolidated, and cured
The most common use for Portland cement is in the production of concrete Concrete is a composite material consisting of aggregate (gravel and sand), cement, and waterAs a construction material, concrete can be cast in almost any shape desired, and once hardened, can become a structural (load bearing) element
What Is the Main Ingredient in Cement? | Reference
The ingredients of cement include limestone, shells and chalk combined with shale, slate, clay, silica sand, blast furnace slag and iron ore These ingredients are heated at high temperatures to form a rock-like substance, which is then ground into cement powder Portland cement is the material used to ,
