Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout.It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and is usually made from limestone.It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker . Sustainable. Whereas the U.S. standard for portland cement allows for up to 5% of clinker to be replaced by limestone, the standard for blended cement allows for 5% to 15% limestone replacement in PLC (Type IL). These combinations are equivalent to the respective factory-made composite cements listed below: CEM II/A or B-S, V, -L or -LL . It is called Portland cement because its inventor, Joseph Aspdin, thought . Almost all drilling cements are made of Portland cement, a calcined (burned) blend of limestone and clay. Calcium carbonate loves to precipitate out of solution, a feature that allowed early organisms in Earth's seas to make shells that have left an amazing fossil record - a record that is the backbone of geological . Portland cement clinker is formed by burning calcium and siliceous raw materials in a kiln. In practice, portland-limestone cement is ground to a higher fineness compared to portland cement.
