The size of the particles of the cement is its fineness.The required fineness of good cement is achieved through grinding the clinker in the last step of cement production process.As hydration rate of cement is directly related to the cement particle size, fineness of cement is very important

The cement is obtained by burning a mixture of calcarious (calcium) and argillaceous (clay) material at a very high temperature and then grinding the clinker so produced to a fine powder. It was first produced by a mason Joseph Aspdin in England in 1924. He patented it as portland cement. Different Types of …

Cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cements used in construction are usually inorganic, often lime or calcium silicate based, and can be characterized as either hydraulic or non-hydraulic, depending on the ability of the cement to set in the presence of water

Hydraulic Cement is a product used to stop water and leaks in concrete and masonry structures. Hydraulic cement is used widely in the construction industry sealing structures below grade and in situations where structures can be affected or submerged in water.
