What Is Self Compact Concrete? Making concrete structures without vibration has been done in the past. For example, the placement of concrete under-water is done by the use of tremie without vibration. Shaft concrete and mass concrete may be successfully placed without vibration. But the above examples of concrete are normally of lower strength and…

What Is Pedestal? The term “Pedestal”, so far in the Civil Engineering field is concerned, is a compressive structural member which is provided in between the footing and column, in order to transfer the load uniformly into the footing. In early times, the pedestals were not much in use. It is later found out, when…
