What are Aggregate in Construction Industry ? In the construction industry, aggregate are used as filler material in the production of concrete and mortar. Aggregate occupy around 70% to 80% of the volume of the concrete, reduce shrinkage effects and minimize costs. The coarse aggregate form the main matrix of concrete and the fine aggregates … Read more Aggregate | Classification & Test on Aggregate
Particle Size Distribution Particle Size Distribution or the percentage of grains of different sizes in a given soil is an important property of soil. Particle size analysis of coarse soils is carried out by sieve analysis or mechanical analysis whereas fine-grained soils are analysed by hydrometer analysis. In general, a combined analysis is carried out … Read more Particle Size Distribution of Soil
Definition Of Timber Timber or Lumber is nothing but wood used for building and other engineering purposes. It is obtained from the trunk of trees. Trees give different types of timber which can be used for different kinds of works. Classification of Trees : Exogenous Trees : These trees grow outward and have distinct consecutive … Read more Timber – Classification, Types, Defects in Timber
Concept of Geographic Information System In today’s modern world most of the decisions involving planning and development are based on consideration of the information available regarding location or geographic information. such information regarding location is usually referred to as Geographic Information System or GIS. Geographic Information System should include not only the data processing functions … Read more What is Geographic Information System (GIS) ?
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
