Definition of Kelly Clamp Kelly clamp is defined as a vertically movable pinch clamp fastened to a graduated stick to allow the interpretation of the penetration depth of the kelly ball. These are clamped only at top of the device prior to the experiment then dropped to interact with the edge of the tower until the…
What Is a Concrete Surface Retarder? Surface retarders, also know surface “deactivators,” are applied to fresh concrete to chemically delay the set of the surface mortar. Unlike concrete set retarders, they allow the rest of the concrete to cure normally, without affecting the setting rate or strength gain. Because surface retarders work their magic by…
What Is Pier? These Piers provide vertical supports for spans at intermediate of different points and perform both main functions: transferring vertical superstructure loads to the foundations and resisting horizontal forces acting on this bridge. Although piers are designed to resist vertical loads, it is becoming common to design piers to resist high lateral loads…
Structural Audit Definition Structural Audit can be defined as a very important approach to understanding the distress level or condition of any existing civil engineering structure or a building. The initially specialized technique used to inspect a building or a civil engineering structure to evaluate its general health is known as Structural Audit. Doing a…
Introduction of a Suspension Bridge Suspension bridges are one of the most popular choices in Bridge construction nowadays, due to the numerous advantages a suspension bridge provides over other bridge structures. As the name indicates, a suspension bridge is the one in which the bridge deck slab suspends between two towers, or in other words,…
What Is Cantilever? Cantilever is basically a structural element that extends horizontally and has supported at only one end. The cantilever is the structures that are fixed at one end and free at another end. Cantilever structures are widely used in the construction of cantilever bridges, cantilever slab, and balconies. The best example of the…
Kerbs In Roads The top of the kerbs should be 100 mm above the road surface. With the pavement, the kerb is laid on a concrete bed of at least 100 mm thickness. At least 150 mm to provide lateral support the kerbing should be provided. To the concrete level, kerbs can be tapped. the…
What Is Concrete Resurfacing? Concrete resurfacing is the process to provide a brand new look to damaged concrete. In the process of resurfacing of concrete, a concrete coating is applied on the surface of existing concrete. Concrete resurfacing is a time-consuming process, and it’s very much labour-intensive process so, it’s a little bit expensive…
What Is Cinder Block? Cinder blocks are totally different from concrete blocks. Concrete and cinder blocks are made from the same basic components; however, there is a special key component for cinder blocks created for various functions. Cinder blocks are also made of concrete, however, the mixture includes coal ash. Concrete blocks are lighter than…
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…
