That is Portland cement was first produced by a British stone mason, Joseph Aspdin in 1824, who cooked cement in his kitchen. He heated a mixture of limestone and clay powder in his kitchen, and grind the mixture into powder creating cement, that hardens when mixed with water. The name Portland was given by the inventor as it resembles a stone ...

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.
This paper aims to review the progress in cement clinker chemistry since the last International Conference on the Chemistry of Cement in 2011. Although Portland cement clinker is still, by far, the most important compound of modern cements we show that there is a strong development of alternatives. This is mainly due to the emission of carbon ...

Providing a solid grounding in core topic areas, the book will enable the reader to manage the problems and pitfalls that can arise in engineering …
Cement is a key ingredient of concrete, typically making up 10 to 15 percent of the concrete mix by volume. Portland cement and portland-limestone cement are the most common types of cement used in concrete. In concrete, a paste made of cement and water is mixed with aggregates (sand, gravel, or crushed stone).
Ordinary Portland cement is one of the most widely used type of Cement. Types, properties, constituents, manufacture, uses and advantages of Ordinary Portland Cement is discussed. In 1824 Joseph As…
Chemical composition. Portland cement is made up of four main compounds: tricalcium silicate (3CaO · SiO 2 ), dicalcium silicate (2CaO · SiO 2 ), tricalcium aluminate (3CaO · Al 2 O 3 ), and a tetra-calcium aluminoferrite (4CaO · Al 2 O 3 Fe 2 O 3 ).

Ordinary Portland cement is the most widely used type of cement 11, and its main constituents include alite (50–70 wt.%), belite (15–30 wt.%), ferrite (5–15 wt.%), and …
Gypsum in portland cement controls the flash set (the reaction of C 3A with water is very violent and leads to immediate stiffening ofthe paste, known as flash set) that might otherwise result from the rapid formation of the calcium aluminate hydrates. Hydration of portland cement : The chemistry of cement hydration is a very complex phenomenon.
2.1. Portland cement chemistry. Portland cement (PC) is composed of a number of chemical oxides that can be cumbersome when written in conventional notation; therefore, cement chemists often use an alternative nomenclature system (presented in Table 2).
Portland cement is suitable for wet climates and can be used underwater. Different types or blends of Portland cement include Portland blast furnace slag cement, Portland fly-ash cement, Portland pozzolan cement, Portland-silica fume cement, masonry cement, expansive cement, white blended cement, colored cement, and very finely ground cement.
Hydration of Portland Cement. Introduction Portland cement is a hydraulic cement, hence it derives its strength from chemical reactions between the cement and water. The process is known as hydration. Cement consists of the following major compounds (see composition of cement): Tricalcium silicate, C 3 S; Dicalcium silicate, C 2 S; Tricalcium ...
