Since the production of 1 t of Portland cement generates the emission of up to 1 t of CO 2, it is imperative to use as little cement as possible when building concrete infrastructure and to build them as durable and sustainable as possible. In this context, this chapter illustrates that concrete with low water/cement ratio is more sustainable than normal w/c concrete, that increasing the

Using less cement is the most effective way to reduce the carbon footprint of concrete. Carbon Smart Attributes Less cement = less carbon. After reducing the carbon impact of cement production, additional carbon reductions can be made by reducing the amount of cement used per unit volume of concrete. Substitute cement with supplementary cementitious materials (SCMs) from non-fossil fuel based

Most new cement plant is of this type. The principle is similar to that of the dry process preheater system but with the major addition of another burner, or precalciner. With the additional heat, about 85%95% of the meal is decarbonated before it enters the kiln.

The work of early investigators using optical and X-ray techniques, starting in 1882 with Le Chatelier, has shown that most Portland cement clinkers contain four principal compounds. These are tricalcium silicate (3CaO.SiO 2 ), aluminate (3CaO.Al 2 O 3 ) and a ferrite phase from the (2CaO.Fe 2 O 3 - 6CaO.2Al 2 O 3 .Fe 2 O 3 ) solid solution series that at one time was considered to have the

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together.Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.Concrete is the most widely used material in existence and is only behind water as
