INTRODUCTION Cement is a commonly used binding material in the construction. Cement is obtained by burning a mixture of calcareous (calcium) and argillaceous (clay) material at a very high temperature then grinding the clinker so produced to a fine powder. It was first produced by a mason Joseph Aspdin in England in He patented it as Portland cement.

History of Portland Cement • First cements produced by early Greeks and Romans from volcanic ash mixed with slaked lime. • This art was lost during the Middle Ages. • Portland cement developed in England by bricklayer Joseph Aspdin in early 1800's. • Called "Portland" because concrete made with it
Cement is the most essential construction material that acts as a binding agent for concrete, laying bricks and more. From limestone to clay and supplementary additives, each ingredient contributes to the durability and strength of cement. Let us learn about the essential raw materials used for cement production. Composition of Cement

Why the curing of cement concrete is required? The curing of cement concrete is required for the following reasons-1. To prevent the concrete from drying out prematurely due to solar radiation and wind. 2. To maintain the concrete temperature by allowing the hydration process. 3. To harden and bond with internal materials and reinforcement.
