Abstract The Sky Bus technology offered by Konkan Railway Corporation meets the above requirements, and re-defines the thinking and planning for urban transport being an Eco-friendly Mass urban transport system revolutionizing urban life. It is a patented technology developed for the new millennium and will cause a paradigm shift in urban transportation all over the world. Sky Bus is based on the concept of Sky Wheels presented in 1989 at the World Congress for Railway Research by Mr. B Rajaram, Managing Director of KRCL at Bologna University , Italy . The sky bus uses pre - fabricated latest construction technologies, which save time and money resulting in easy execution of the project in busy urban areas without disturbing the existing traffic pattern. All these structural engineering methods are well - proven. They have IT tools for economical communication and control. The 3 phase asynchronous AC electrical motor used for the propulsion of sky buses is also well proven and widely

Recycling of Waste Concrete Recycling of waste concrete is done to reuse the concrete rubble as aggregates in concrete. The recycled aggregates have less crushing strength, impact resistance, specific gravity and has more absorption value as compared to fresh aggregates. Necessity of Concrete Recycling: Millions of tonnes of waste concrete is generated every year around the world due to following reasons: Demolition of old structure, Destruction of buildings and structures during earthquakes and wars, Removal of useless concrete from structures, buildings, road pavements etc. Waste concrete generated due to concrete cube and cylinder testing, destructive methods of testing of existing structures etc. Advantages of Concrete Recycling: Usually demolished concrete were shipped to landfills for disposal, but due to greater environmental awareness, the concrete is being recycled for reuse in concrete works. There are a variety of benefits in recycling concrete rather than dumping it or bury

  Different Types of Concrete Pump Concrete pumping has become one of the most widely used approaches to place concrete. With the increasing use of pumping to place concrete, the development and refinement of the practice to ensure successful concrete pumping is becoming an important need for the concrete construction industry. Pumping enables the transport of concrete to forms and molds while increasing the speed of delivery and allowing access to hard-to-reach areas. Concrete pumps are likely to vary according to the end-use industry and quality of the concrete required for construction activities. Consequently, the optimization and development of prediction methods for concrete pumping is becoming a crucial issue for the concrete industry. Discussed below are different types of concrete pumps being used across projects. Stationary Concrete Pump The stationary concrete pump is small, light and features a powerful dual-piston pump. It is used for manual, not synchronised additives add

 

Introduction The growing population along with limited land resources have allowed Indian real estate to expand vertically. As a result, high-rise buildings are being developed in many parts of the country, with residential buildings reaching as high as 100 stories.   For working professionals in cities, high-rises are probably the most popular option. High-rises are the most common type of construction in cities because they allow a large number of people to live close to city centres.  Units on the upper floors, unlike those on the lower floors, have more privacy because they are located far away from the housing project's common areas. What is a High-Rise Building? In real estate terms, any structure taller than 75 feet is considered a high-rise. The main benefit of living in a high-rise is that you get unobstructed views of the scenery. It provides excellent natural ventilation as well as fresh air, as well as being away from street pollution.  Pros of high rise buildings: A no

  Water treatment plants are crucial in providing communities with access to clean and safe drinking water. These facilities employ various processes to eliminate impurities and contaminants, ensuring the suitability of water for consumption. In this comprehensive guide, we will explore the fundamental aspects of water treatment plants, including the key processes, equipment, and considerations involved. By gaining a solid understanding of water treatment fundamentals, we can better comprehend the importance of these plants in safeguarding public health and preserving the environment. Importance of Water Treatment Water treatment plays a critical role due to the escalating pollution of natural water sources. It is instrumental in protecting public health by removing harmful substances, including pathogens, chemicals, and pollutants. This section will delve into the significance of water treatment, emphasizing the consequences of consuming contaminated water and the advantages of ha
