Frequently asked questions

Q1: What is a Portland cement?

A1: Concrete is basically made from portland cement, water and aggregates. Portland cement is nothing but a hydraulic cement that hardens in water to form a water-resistant compound. The hydration products as output act as binder to hold the aggregates together to form concrete. The colour and quality of the resulting concrete which are similar to Portland stone, a kind of limestone found in England. That is the reason it is called Portland cement.

Q2: How does portland cement manufactured?
A2: Portland cement is manufactured by nicely blending the appropriate mixture of limestone and clay or shale together and by heating them at 1450C in a rotary kiln. The preliminary steps are a variety of crushing and blending operations. In the beginning, the raw feed must have a uniform composition through out and be a size fine enough so that reactions among the components can be complete in the kiln. Subsequently, the burned clinker is grounded with gypsum to form the grey powder known as Portland cement which everyone is familiar with.
Q3: What is hydration?
A3: The setting and hardening of concrete are the end result of chemical and physical processes which take place between Portland cement and water. The process is called hydration. Knowledge of the chemistry of hydration is necessary to understand the properties and behavior of cement and concrete.
