Historic Indian Buildings Starting from the north to south and east to west, India is full of glorious pasts. This past also holds all its historical remains that prove the rich past of the nation. Back in ancient and medieval history, there were many rulers who build exceptional buildings. These buildings were wonders of those times. Not only of those times are these historical Indian buildings still a wonder. Some of these also hold a place in the Seven Wonders of the World. One such great building is the Taj Mahal. Besides, the construction of these buildings is still a mystery for modern architects. This is because; without any modern technologies, the emperors were capable of making these huge buildings in years. Some of the architectures took a lot of effort and hard work of labourers in thousands. Here in this post, you are going to explore some of the historic Indian Buildings of India.  Nalanda, Bihar  This is a great Indian Building that is in ruin now. In the past, ...

  TRIGONOMETRY IN CIVIL ENGINEERING The Greek words “trigōnon” and “metron,” meaning triangle and measurement respectively. The civil engineers use trigonometry on a daily basis. Civil engineering is an important part of the construction process. Whether it’s determining how many braces they need to support a bridge or planning how steeply to design a road along, around or through a hill, both engineers and construction teams are very focused on mathematics of their projects, including trigonometry. BRIDGES AND CONSTRUCTION Bridges are associated with triangles and trigonometry.Looking at many historic and some modern bridges, you will see many repeating and nested triangles. Triangles evenly distribute weight from any direction, when applied correctly. Using trigonometry to solve bridge-related problems, you can determine how much force will be applied to the joints between the triangles and in which direction. TRIGONOMETRY IN CONSTRUCTION Even in smaller projects you'...

  Most Useful Civil Engineering Software The Architecture, Engineering, and construction industry is moving towards digitization. The construction business has started adopting and implementing digital techniques through various civil engineering software programs and technologies. Although conventional methods and construction practices are still used, digitization is of utter importance in the modern era of architecture, engineering, and construction. If you are a civil engineering student or a professional working in the Architectural, Engineering, and Construction (AEC) industry, a list of software programs will assist you daily. As the construction business is digitizing, it is essential to implement digitized methods in your construction projects. Several operations, processes, and techniques are involved in construction projects, such as drafting, modeling, estimation, project management, etc. Each of them requires different software or software packages for the e...

  NON-DESTRUCTIVE TESTING (NDT) Non-destructive testing (NDT) is a testing and analysis technique used by industry to evaluate the properties of a material, component, structure or system for characteristic differences or welding defects and discontinuities without causing damage to the original part. NDT also known as non-destructive examination (NDE), non-destructive inspection (NDI) and non-destructive evaluation (NDE). NON-DESTRUCTIVE TESTING METHODS Acoustic Emission Testing (AE) Electromagnetic Testing (ET) Ground Penetrating Radar (GPR) Laser Testing Methods (LM) Leak Testing (LT) Magnetic Flux Leakage (MFL) Microwave Testing Liquid Penetrant Testing (PT) Magnetic Particle Testing (MT) Neutron Radiographic Testing (NR) Radiographic Testing (RT) Thermal/Infrared Testing (IRT) Pulse Echo Inspection Through Transmission Testing Time of Flight Diffraction (ToFD) Immersion Testing Air Coupled Testing Electromagnetic Acoustic Transducer (EMA...

What is meant by soil erosion? In general terms soil erosion implies the physical removal of top soil by various agents, including 1. Rainwater flowing over and through the soil profile 2. Wind 3.Ice 4.Gravitational pull.  

  Test Methods for Self Compacting Concrete   A concrete mix can only be classified as self compacting concrete  if the requirements for all the following three workability properties are fulfilled. 1.      Filling ability 2.      Passing ability and 3.      Segregation resistance. Filling Ability of Self Compacting Concrete It is the ability of SCC to flow into all spaces within the formwork under its own weight. Tests, such as slump flow, V-funnel etc, are used to determine the filling ability of fresh concrete. Passing Ability of Self Compacting Concrete It is the ability of SCC to flow through tight openings, such as spaces between steel reinforcing bars, under its own weight. Passing ability can be determined by using U-box, L-box, Fill-box, and J-ring test methods. Segregation Resistance The self compacting concrete must meet the filling ability and passing ability with uniform composition throughout the pr...

  Self-compacting concrete also known as self-consolidating concrete. It is one of the most widely used concrete types, mainly because of its self-compacting characteristics and strength. SCC is a highly flowable, non-segregating, special concrete type that can settle into formworks, by means of its own weight. SCC does not require compaction using external force from mechanical equipment such as immersion vibrators. SCC was developed in Japan in 1980s in order to achieve high-performance durable concrete structures, and with advancements in concrete technology its use has become widespread all over the world. The advantages of SCC in its fresh and hardened states include economic efficiency, improvement in working and living environment. Compared with ordinary concrete, SCC includes large amounts of binder, super plasticizer, and/or viscosity modifying admixtures.   The placement of SCC is faster and requires less labour. The appearance (surface finish), me...
