Cement and Concrete Production Cement is the key ingredient in concrete products. Comprising roughly 12% of the average residential-grade ready mix concrete, cement is the binding agent that holds sand and other aggregates together in a hard, stone-like mass. Portland cement accounts for about 95% of the cement produced in North America.

Cement concrete is an important construction material. Its importance is increasing every day. It is a composite material consisting of a binding material, which is essentially cement, inert mineral Filler, known as aggregates and water. Thus cement concrete can be prepared by mixing above ingredients in a fixed proportion.
From 2015 to 2020, the global clinker-to-cement ratio is estimated to have increased at an average of 1.6% per year, reaching an estimated 0.72 in 2020; this rise was the main reason for the increase in direct CO 2 intensity of …

Contrary to popular belief, concrete and cement are not the same thing; cement is actually just a component of concrete. Concrete is made up of three basic components: water, aggregate (rock, sand, or gravel) and Portland cement. Cement, usually in powder form, acts as a binding agent when mixed with water and aggregates.
