A cement truck was parked two feet away from the west wall, unloading 6 yards of cement into the basement. The 2-foot area around the foundation had been backfilled about an hour and a half before the cement finishers began their work. One of the employees directed the cement chute, starting at the northwest corner of the building.

Size, shape, texture play an important role in workability of concrete. With more surface area of sand, the demand for cement and water increases to bond the sand with coarse aggregates. The control over these physical properties of manufacturing sand make the concrete require less amount of water and provide higher workable concrete.
Portland cement gets its strength from chemical reactions between the cement and water. The process is known as hydration. This is a complex process that is best understood by first understanding the chemical composition of cement. Manufacture of cement Portland cement is manufactured by crushing, milling and proportioning the following materials:

The cement, which is not stored, transported and handled properly, will lose its strength and in turn, influence the strength of concrete in which it is used. 3.4.CEMENT PACKAGING: Cement packed in bags using very porous material is more susceptible to loss of strength and hence packaging material of cement bags can greatly influence the strength.

What is cement? Cement has been in use as far back as the time of the ancient Egyptians, Greeks and Romans. Variations of cement have been used by humans to 'glue together' stone and other building materials for centuries. Cement is a term used today to refer to the fine powdery material left after 'clinker' has been 'milled'. When mixed with water, cement …
