Bridge Failure Bridge failure don’t occure often but when they do the results are spectacular and unforgettable. once you have seen the footage of the ‘Tacoma Narrows Bridge‘ resonating in a gale, bucking back and forth before the deck breaks up and crashes to the river below you will never forget it. Bridge always collapse … Read more Bridge Failure in Civil Engineering
Importance of Global Positioning System (GPS) in Civil Engineering Global Positioning System is a system developed by the US Department Of Defence (D.O.D) for military as well as Civil operations. The D.O.D sustains it. The Global Positioning System provides quickly, accurate and inexpensively to determine the time, position and velocity of any object on the … Read more Global Positioning System { GPS } in Surveying
What is Contour line in Surveying ? A Contour line may be defined as an imaginary line passing through the points of equal devotion. A contour line may also be defined as the intersection of a level surface with the surface of the earth. When the contours are drawn underwater, they are termed as Submarine … Read more Contour line and Methods of Contouring
Plane Table Surveying Plane Table Surveying is one of the most rapid method of surveying. The plane table is an instrument used for surveying by a graphical method in which the field work and plotting are done simultaneously. The main advantage of plane table surveying is that the topographic features to be mapped are in … Read more Plane Table Surveying : Advantages & Disadvantages
What is Column Failure ? Columns are used to transfer the load vertically to the horizontal beams. Every material used in the building experience both compression and tension stress. Columns consist of two major material which are concrete and steel. Engineers do calculate the total stress caused by the live load and dead load of … Read more Column Failure and It’s Types
What are the Initial and Final Setting Time of Cement. Initial Setting Time of Cement. Initial setting time of cement is defined as the time elapsed between the moments when water is added to the cement to the time when the cement paste starts losing its plasticity. It can also be defined as the time … Read more Initial and Final Setting Time of Cement
Hydration of Cement The Chemical reaction that takes place between cement and water is called as hydration of cement. This reacion is exothermic in nature, due to which considerable amount of heat is released during hydration of cement. This is called as ‘heat of hydration’. The hydration of cement is not a sudden process. This … Read more What is Hydration of Cement ?
What is Fly Ash ? Fly ash is considered as one of the most important and advantageous waste material in construction industry. It is residue produced during the combustion of coal or any other form of coal. Nearly 30% of the coal is converted into ash on burning out of which 75% is in fine … Read more Fly Ash : Properties, Uses & Disadvantages
Concept of Stress Strain Curve For Mild Steel Generally mild steel rods are highly preferred for many construction purposes. As it has high tensile strength when used with concrete, knowing the behavior of mild steel rod under loading helps in choosing for better use. This behavior of a mild steel rod under loading can be … Read more Stress Strain Curve For Mild Steel
What is Workability of Concrete ? The term ‘Workability of Concrete’ is defined as the property of freshly mixed concrete which determines the ease and homogeneity with which it can be mixed placed, consolidated and finished. An ideal water-cement ratio alone is not going to give maximum strength. 100% compaction of concrete is an important … Read more Workability of Concrete & Factors Affecting It
