Portland cement ScienceDirect
Portland cement is at the same time the fruit of simple technology and a complex science. It consist in firing at 1450 °C very simple pulverized raw materials having a very specific composition to produce an intermediate product called Portland cement clinker or simply clinker.Clinker is composed of 4 minerals that react with water to creates strong Portland cement gets its strength from chemical reactions between the cement and water. The process is known as hydration. This is a complex process that is best understood by first understanding the chemical composition of cement. Manufacture of cement. Portland cement is manufactured by crushing, milling and proportioning the following materials:What is the manufacturing process of Portland Cement?

Production of cement and its environmental impact
Cement production is a highly energy intensive process and the energy consumption of cement industry is nearly 5% of the total global industrial energy consumption. The theoretical energy consumption for producing 1 kg of Portland clinker is about 1.76 Mega joules.The thermal gravimetric analysis (TG) is a common method for the examination of the carbonation progress of cement-based materials. Unfortunately, the thermal properties of some components complicate the evaluation of TG results.

Everything You Need to Know About Portland Cement
Portland cement is a type of cement that is used as the binding agent in concrete. It is made by heating limestone and clay to high temperatures in a kiln. Portland cement was invented in 1824 by Englishman Joseph Aspdin and patented in 1825. The name comes from its similarity to the stone quarried on the Isle of Portland, Dorset,
