Hardware and Maintanance
The raw materials required for the manufacture of OPC are calcareous material such as limestone or chalk and argilaceous materials such as shale or clay. A mixture of these materials is burnt at a high temperature of approximately 1400 0C in a rotary kiln to form clinker. The clinker is then cooled and grounded with a requisite amount of gypsum into fine powder known as portland cement.
OPC is a gray coloured powder. It is capable of bonding mineral fragments into a compact whole when mixed with water. This hydration process results in a progressive stiffening, hardening and strength development.
