WHAT IS PORTLAND CEMENT?
Portland cement constitutes a finely ground powder, formed mainly by calcium silicates and, to a lesser extent, by calcium illuminates.
When mixed with water, it forms a paste that sets and hardens at room temperature.
It is also known as “hydraulic cement”, because it is capable of setting and hardening when mixed with water, because the chemical reaction between the
two creates a material with excellent binding properties.
It is also known as “grey cement”.
Portland Cement can be used for all kinds of constructions as it is compatible with practically all conventional construction materials. It’s a very versatile and high-quality product.
It is used to make concrete blocks, pavers, bricks, and to build reinforced concrete projects or structures that require a rapid removal of form work.
“Being so strong and durable has made Portland cement a favourite.”
These are some of its most common uses:
- Stairs, fountains, benches, wastebins, planters and public stairs.
- Columns, telephone poles or streetlights.
- Roads, paths, sport courts.
- Large-scale civil works (piers, tunnels, buildings, bridges, dams.).
- Floors.
- Cement mortar for masonry work.
- Cement grout to fill cracks in concrete works.
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, 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. Its name is derived from its resemblance to Portland stone which was quarried on the Isle of Portland in Dorset, England. It was named by Joseph Aspdin who obtained a patent for it in 1824. However, his son William Aspdin is regarded as the inventor of “modern” Portland cement due to his developments in the 1840s.
