Properties of Concrete Concrete is an artificial conglomerate stone made essentially of Portland cement, water, and aggregates. Properties of Concrete While cement in one form or another has been around for centuries, the type we use was invented in 1824 in Britain. It was named Portland cement because it looked like the
Today, large concrete structures (for example, dams and multi-story car parks) are usually made with reinforced concrete. Composition. Concrete is a composite material, comprising a matrix of aggregate (typically a rocky material) and a binder (typically Portland cement
Cement Composition: Cement. Aggregates. Admixtures. Mixture Design. Fresh Concrete. Hardened Concrete. Dimensional Stability. Durability . Oxide composition of cement. Four major oxides of cement, in the decreasing order, are CaO, SiO 2, Al 2 O 3, and Fe 2 O 3.
Cement can be defined as the bonding material having cohesive & adhesive properties which makes it capable to unite the different construction materials and form the compacted assembly. Ordinary/Normal Portland cement is one of the most widely used type of Portland Cement. The name Portland cement was given by Joseph Aspdin in 1824 due to its similarity in
To accurately calculate the mineral composition of a cement from the oxide composition it is necessary to estimate the true composition of the cement minerals in the clinker and to account for phases other than the main four cement minerals such as gypsum. A more complete description of this useful technique is given in ref. .
cement faces its toughest challenge under ground—in oil and gas wells where envi- ronmental conditions are far more severe than any encountered on the earth's surface. This artic e outlines the chemistry of port- land cement, the variety used to cement casings in wells and provide zona isolation, and explains how additives faci itate cement
(France) (CMK) were used. Chemical composition and physical properties of the starting materials are shown in Tabs. 1 and 2. 2.2 Applied experimental methods . The chemical composition of cement is determined by standard methods , while chemical composition of metakaolin is determined by
HYDRATION OF CEMENT It is the reaction (s eries of chemical reactions) of cement with water to form the binding material. In other words, in the presence of water, the silicates (C3S and C2S) and aluminates (C3A and C4AF) form products of hydration which in time produce a firm and hard mass -the hydrated cement

We first discuss cement production and special nomenclature used by cement industrialists in expressing the composition of their cement products. We reveal different types of cement products, their compositions, properties, and typical uses. Wherever possible, we tend to give reasons as to why a particular cement type is more suitable for a given purpose than other types.
Table 2: Composition of portland cement with chemical composition and weight percent. When water is added to cement, each of the compounds undergoes hydration and contributes to the final concrete product. Only the calcium silicates contribute to strength. Tricalcium silicate is responsible for most of the early strength (first 7 days).
