Water is allowed to dry, the strength of solid mass keeps Time has an important role on strength of developedĬement mortar. Soil and the River sand obtained from riverbed isĬonsidered excellent for preparing mortar and concrete. On the other hand, Pit sand is obtained from pits in the For example, Sea sand obtained from seaĬontains unwanted salts and retards setting of cement Sand obtained from different sources has different Must be kept dry in order to retain their strength. Produces hydrates that are not water-soluble. The chemical reaction that results when theĪnhydrous cement powder is mixed with water
Of the mixture’s water content they can hardenĮven underwater or when constantly exposed to wet Portland cement) harden because of hydrationĬhemical reactions that occurs independently Portland cement may be gray or white.Ĭement used in construction is characterised as Once hardened, can become a structural (load baering)Įlement. As a construction material,Ĭoncrete can be cast in almost any shape desired and Concrete is aĬomposite material consisting of aggregate (gravel and The most common use for portlandĬement is in the production of concrete.
