Cerial is used for binding the other materials together, just like glue does. The juncture at which concrete and cement intermix is on the highways! It is here that we use asphalt cement, a by-product of petroleum, which is also often called asphalt concrete. Nevertheless, while dealing with concrete it becomes very important that a few properties of the maoncrete is indeed not a natural substance.
One cannot find it embedded within rock layers or in wood stocks. It has to be artificially made by effectively mixing water, rock and Portland cement. Generally a number of people mistake concrete and cement and use the words in place of each other. However, it is not so. It must be borne in mind that while concrete is the actual structural material; cement is just an ingredient which is made use of, in its formation. Most garages, parking lots, driveways and subways are made of concrete and not cement. The use of cement primarily lies in construction of buildings which we see around us every day. Cement is actually a material be considered.
Properties-
Concrete, as a construction material, consists of a few properties which must be considered and kept in mind. These properties not only shape the way concrete would be used but also determine how long it would last. Such properties are:
The nature of the mix of concrete is workable. It can be effectively intermixed, consolidated, placed and leveled. Moreover, by assistance of a pave, fine texture and a smooth finish can be delivered to it as well. In fact, all you need for working with concrete is a concrete mixer, a truck and a few workmen!
Depending upon what task are you using the concrete mix to accomplish, the different qualities of the material would be brought into effect. For instance, its resistance to freezing and thawing, low permeability, long lasting strength, durability, endurance etc is kept into view while putting concrete into application.
The quality of concrete largely depends upon the ratio of water and cement used in its making. It is considered an economic measure if you minimize the requirement of water. With this, the requirement of cement would automatically be minimized, resulting into a huge reduction in the cost of operations.
With concrete, it must be remembered to use the stiffest mix possible but with an addition of large sized aggregates. A proper balance ought to be maintained between the use of fine and coarse aggregates. By this, the resultant concrete has all the qualities that you desire to achieve out of it.
Concrete, has been used since long to give shape to different structures and constructions. All through the time, it has indeed been its properties which have heralded the attention of its makers and users.
