Feb 21, 20200183324 Cement concrete- Cement concrete is a mixture of cement, sand, pebbles or crushed rock and water, which, when placed in the skeleton of forms and allowed to cure, becomes hard like a stone. Cement concrete has attained the status of a major building material in all branches of modern construction because of the following reasons 1.
Ferrite is a fluxing agent. It reduces the melting temperature of the raw materials in the kiln from 3,000176F to 2,600176F. Though it hydrates rapidly, it does not contribute much to the strength of the cement. Magnesia MgO The manufacturing process of Portland cement uses magnesia as a raw material in dry process plants.
manufacturing process for portland cement. While it has ancient roots, concrete, as we know it today, is a modern and highly advanced building material. In the last 150 years, concrete has become one of the most widely used building materials on earth. Concrete is the most commonly used construction material in the world today.
