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 ...

However, it is a portland cement's chemical properties that determine its physical properties and how it cures. Therefore, a basic understanding of portland cement chemistry can help one understand how and why it behaves as it does. This section briefly describes the basic chemical composition of a typical portland cement and how it hydrates.
- Portland cement is produced by heating limestone, clay, and other materials to form clinker, which is then ground with gypsum. - The main compounds in clinker are tricalcium silicate, dicalcium silicate, tricalcium aluminate, and tetracalcium aluminoferrite. - The proportions of calcium oxide, silicon dioxide, aluminum oxide, and iron oxide ...

H F W Taylor was for many years Professor of Inorganic Chemistry at he University of Aberdeen, Scotland. Since 1948, his main research interest has been the chemistry of cement. His early work laid the foundations of our understanding of the structure at the nanometre level of C-S-H, the principal product formed when cement is mixed with water, and the one mainly reponsible …
The microstructural nature of Portland cement-based products is complex and gives rise to time-dependent physical and mechanical properties, with significant changes taking place over periods of many months or even years. These effects are more fundamental than the continuing hydration reaction of the initial unhydrated cement, and involve slow ...
