What is Cement? Why we are using for construction?

Cement is a fine mineral powder manufactured with very precise processes. Mixed with water, this powder transforms into a paste that binds and hardens when submerged in water. Because the composition and fineness of the powder may vary, cement has different properties depending upon its makeup.

Cement is the main component of concrete. It’s an economical, high-quality construction material used in construction projects worldwide.

Cement is made by grinding together a mixture of limestone and clay, which is then heated at a temperature of 1,450°C. What results is a granular substance called “clinker,” a combination of calcium, silicate, alumina and iron oxide.

Some of the reasons for its popularity in construction site.

01. Cement can be produced in large volumes in controlled condition, packed and transported.

02. Cement is a several times stronger binding material than lime and clay.

03. It can be mixed and used at will with locally available materials at site.

04. When stored properly in ordinary atmosphere it does not deteriorate for reasonably longer time (at least 3 to 4 month).

05. When mixed with water, starts setting and gain sufficient strength in a day or two, where as other binding materials require much longer time. Hence increase speed of construction.

06. It can withstand compressive stresses well. Where tension and shear stresses occurs it gives good bond to steel reinforcement and transfers excess stresses to steel.

07. It is produced from the materials like limestone, hematite, bauxite, clay, etc which are plentifully available in the upper crust of the earth.

08. It imparts strength and durability to building elements. Not only that with cement, the speed of construction also gets faster.

09. It is comparatively cheaper material.
