Physical changes. At elevated temperatures, small cracks form and propagate inside the concrete with increased temperature, possibly caused by differential thermal coefficients of expansion within the cement matrix. Likewise, when water evaporates from concrete, the loss of water impedes the expansion of cement matrix by shrinking.

Properties of Good Cement. It is always desirable to use the best cement in constructions. Therefore, the properties of a cement must be investigated. Although desirable cement properties may vary depending on the type of construction, generally a good cement possesses following properties (which depend upon its composition, thoroughness of burning and fineness of grinding).

Cement has two different types of properties; either physical or chemical properties. Physical Properties of Cement 1.Fineness . It is the biggest factor for undeterrable strength of cement. Higher fineness leads to higher strength. Higher fineness denotes that there is more area for cement water reaction resulting increase in strength.

The important physical properties of cement are fineness, setting time, soundness, standard consistency, and compressive strength. A good quality cement must be uniform in color and free from lumps. When taken in hand, the cement must be cool. Quality cement, when thrown in small amounts into the water must sink.

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together.Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.Concrete is the most widely used material in existence and is only behind water as ...
