How to use portland cement? Mix portland cement with water and an aggregate (usually gravel and sand) to make concrete. The cement is then cast into the desired shape and can become a load-bearing material when it dries. Mix portland cement with sand and water to make mortar.
How to Use Portland Cement?
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 usually originates from limestone.
It is a fine powder produced by heating limestone and clay minerals in a kiln to form clinker, grinding the clinker, and adding 2 to 3 percent of gypsum.
Several types of Portland cement are available. The most common, called ordinary Portland cement (OPC), is grey, but white Portland cement is also available.
It is the basis for most commercial concretes, mortars, and grouts. Portland cement clinker is made by heating in a kiln a homogeneous mixture of raw materials to a sintering temperature, which is about 1450 °C for modern cements.
The aluminium oxide and iron oxide are present as a flux and contribute little to the strength. For special cements, such as Low Heat (LH) and Sulfate Resistant (SR) types, it is necessary to limit the amount of tricalcium aluminate (3CaO•Al2O
