Buildings are inherently linked to their usage and surroundings and hence their indoor environment is the result of a range of interactions affected by seasonal and daily changes in climate and by the...
Self-compacting concrete (SCC) is an innovative concrete that does not require vibration for placing and compaction. It is able to flow under its own weight, completely filling formwork and achieving...
In many people’s mind air pollution is associated with contamination of urban air from automobiles exhaust and industrial influents. But every year the indoor air pollution is responsible for the...
The term ferrocement is most commonly applied to a mixture of Portland cement and sand reinforced with layers of woven or expanded steel mesh and closely-spaced small-diameter steel rods rebar. It can...
Any construction activity requires several materials such as concrete, steel, brick, stone, glass, clay, mud, wood, and so on. However, the cement concrete remai...
One of the serious ill-effects of parking is the loss of street space and the resulting traffic congestions. The capacity of the streets is reduced, the journey speed drops down and the journey time and delay increase. The operational cost of vehicles is thereby increased, causing serious economic loss to the community.
Geopolymer materials represent an innovative technology that is generating considerable interest in the construction industry, particularly in light of the ongoing emphasis on sustainability. In contr...
Traffic congestion is a severe problem in many modern cities around the world Traffic congestion has been causing many critical problems and challenges in the major and most populated cities. To trave...
Aluform is a construction system for forming cast in place concrete structure of a Building. Aluform system provides aluminium formwork for RCC, load-bearing ,multi-storeyed buildings and enables the...
Fiber Reinforced Concrete can be defined as a composite material consisting of mixtures of cement, mortar or concrete and discontinuous, discrete, uniformly dispersed suitable fibers. Continuous meshe...
Bitumen is a useful binder for road construction. Different grades of bitumen like 30/40, 60/70 and 80/ 100 are available on the basis of their penetration values. The steady increase in high traffic...
Steel elements used in retrofitting Steel elements in the form of plates, channels, angles, I-sections along with anchor bolts / through bolts could be used for retrofitting a damaged RCC building. Th...
Earthquakes are the natural hazards with high damage potential. However, by utilizing several principles, it is possible to identify and minimise the resulting social and economic losses, which mainly...
Foundation construction for any large bridge takes time. Problems encountered during construction of foundation depend upon type of foundation, soil strata encountered, equipment/plant deployed and lo...
A major long-term element of Intelligent Transportation Systems research and development is Automated highway Systems (AHS). The AHS program is a broad international effort “to provide the...
Audio spot lighting is a very recent technology that creates focused beams of sound similar to light beams coming out of a flashlight. By ‘shining’ sound to one location, specific listeners can be...
With recent advances in wavelength division multiplexing (WDM) technology, the amount of raw bandwidth available in fiber links has increased by many orders of magnitude. Meanwhile, the rapid growth o...
Oceans cover more than 70% of Earth's surface, making them the world's largest solar collectors. The sun's heat warms the surface water a lot more than the deep ocean water, and this temperature diffe...
Adaptive optics is a new technology which is being used now a days in ground based telescopes to remove atmospheric tremor and thus provide a clearer and brighter view of stars seen through ground bas...
Technology is increasing our energy needs, but it is also showing in new ways to generate power more effetely with less impact on the environment. One of the most promising options for supplementing f...
