Cement & Concrete - Portland Cement Association

Cement & Concrete. In its simplest form, concrete is a mixture of paste and aggregates. The paste, composed of portland cement and water, coats the surface of the fine and coarse aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.

Portland Cement - an overview | ScienceDirect Topics

V. Bindiganavile, M. Hoseini, in Developments in the Formulation and Reinforcement of Concrete, 11.3.1 Portland cement. Portland cement is the main cementitious component of foamed concrete. It has been used at dosages varying from as high as 1400 kg/m 3 to as low as 75 kg/m 3 but in practice, usually between 300 and 500 kg/m 3 [3, 6, 11, 12].. In addition to normal Portland cement, rapid

Concrete Sustainability - Slag Cement

Slag cement can replace up to 50% of portland cement in most common concrete mixtures, and up to 80% in massive concrete elements and other specialized structures. Replacing portland cement with slag cement in concrete can save up to 59% of the embodied carbon dioxide emissions and 42% of the embodied energy required to manufacture concrete and
