Modulus of elasticity of concrete is the measurement of the stiffness of the concrete which is a good indicator of strength. At a higher value of modulus of elasticity, the concrete can withstand higher stress and become brittle. In general, Concrete has an elastic modulus in a range of 30 to 50 GPa. In recent …
The separation of constituents of concrete so that their distribution in the concrete mix is not uniform is known as segregation of concrete. Causes of Segregation of Concrete The difference in the sizes of particles and the specific gravity of the mix constituents. The methods of handling concrete also cause segregation. Dropping concrete from a …
Have you ever wondered how concreting operations are performed in cold weather? Is there any difference in concreting in normal and cold weather conditions? Definition of Cold Weather Concreting As per IS Code 7841-2, Any concreting operation done at about 5°C atmospheric temperature or below is termed as cold weather concreting. Effect of cold weather …
Steel Structures have various advantages over RCC Structures such as: A fast rate of construction The lightweight of the structure because of the high strength to weight ratio The full strength of steel structures is available as soon as they are completed. The concrete structures develop their full strength over time. Steel structures are more …
Ganga Expressway is a proposed six-lane greenfield expressway between Meerut and Prayagraj (Allahabad) in Uttar Pradesh. The expressway will run along the Ganga River. So it is named as Ganga Expressway. The length of the proposed expressway alignment is approx 594 km in the first phase. This expressway will ensure high-speed connectivity between the Eastern …
Anji Khad Bridge is proposed (under-construction) cable-stayed railway bridge across Anji Khad river. It will connect Katra and Reasi in Jammu and Kashmir. This bridge is a part of the Udhampur-Srinagar-Baramulla Rail Link (USBRL) project of Northern Railway It is India’s first cable-stayed railway bridge. Earlier, an arch bridge was proposed for this location. The complex …
Contour Surveying is the branch of surveying in which variation in the elevation of the earth’s surface and their relative positions are determined with help of contour lines. The process to find out the contour lines in the ground surface or earth surface is called contouring and a map is produced by this contouring process …
Curing of concrete is the process of preventing the loss of moisture from the fresh concrete. The main aim of curing of concrete is to maintain enough moisture content and favourable temperature in the concrete during hydration of the cementitious materials so that concrete can attain its potential strength and durability. In India, curing is …
