Special functions of concrete:It is used in building residential houses, apartments,etc.,It is used in precast elements.It is used in underwater constructionIt is used to construct infrastructures.
The raw material used for manufacture of cement are limestone and clay. They are ground to form very fine powder and then converted to slurry. The slurry is baked at very high temperature to form granular mass called kilnker. The kilnker is ground and mixed with powdered gypsum to form cement.
As sand is a course granular substances binding agents such as cement and lime can grip to the sand and form stronger bonds - if the mix was all powdery like a cement it would be more line a slurry or even a doh like consistency which would not hold very well under pressure and in weathering. When buildings were first created using mud (wattle and daub) course materials were put in the mix like animal hair and even manure to brake up the slurry like consistency and add strength to the mixure
Cement paste is formed when cement is mixed with water. However, cement mortar is formed when cement is mixed with fine aggregate (sand) and water.The strength of cement mortar is more when compared to cement paste.Shrinkage will be less in cement mortar and high in cement paste.
