Introduction The utilization of the arch and concrete resulted in huge open structures in Roman time, including, sanctuaries (Pantheon), amphitheaters (Colosseum), baths (Caracalla), theaters, streets, bridges and water passages (Kamm, 2007). Ancient Roman designs have persisted for around 2,000 years in light of the fact that the Romans culminated the utilization of three compositional components: the arch, the vault, and concrete. Each of these three essential components alleviated the…

The Roman Roads were built by the military, also surveyors and engineers. The rule fell under the consul rule though. They were built with big stones and sand on the bottom. Then in the middle there were rocks and gravel and on the top there was concrete paving stone. Also on the sides of the roads there was a huge drainage system for all the water when it rains. The Roman Roads stretch from the Appian Way and even to the Mediterranean. This stretch…

The first reinforced concrete high-rise building is the Ingalls Building, built in 1903 in Cincinnati, Ohio. All the key developments in reinforced concrete buildings in that time have contributed in the design and construction of Ingalls Building. Richard W. Steiger defined the Ingalls Building, ‘These developments included heavy monolithic beam-and-slab construction with tension reinforcing, two-way reinforcing systems, and bent bars and stirrups. Also used were hoops and continuous helixes…

Why Concrete Is The Ideal Material For A Septic Tank Building a home in the country is a great idea when you want room for your kids to play away from a congested city. However, being even a short distance from the city limits means you may not be able to connect to the municipal water supply or sewer system. That problem is easy to solve by installing a well, septic tank, and drainfield. One choice you'll have to make is what type of septic tank to install. Here's why concrete is often the…

Sushil Bhandari (1997) defined vibration as a repeated movement in the normal rest position. The parameters involved with vibration are commonly amplitude or displacement and velocity or acceleration of the ground movement (Visvan, 2005). During demolition operation, vibration is normally caused by the impact of fallen structures or by the use of explosives (BS 6187:2000), which could pose detrimental effects of structural damage of adjacent premises, buried services like gas pipes, disturbance…

There are many outstanding achievements that are associated with the Roman civilization. One of the most remarkable of these groundbreaking structures is the aqueducts. The way they were built, and the history of these complex architectural designs contributed to Rome’s prosperity. The everyday life of the Roman people certainly would have been very different if the channels would have failed. The people of Rome used these aqueducts, that were located in mainly rivers with the purpose…

Key Design Drivers The following were the key design drivers for the lower and middle completion string: • Desire not rotate SAS completion string if possible, configuration was set-up with the ability to rotate to bottom (swivel system utilized as contingency) but not as primary method of installation. Note: all previous Husky wells have been installed without rotation • Offset well friction data and the as-drilled 216mm open hole friction factors used to provide accurate T&D analysis prior to…

MARBLE Marble is created from limestone. It is characteristically soft and a metamorphic stone that can be polished. Homeowners must take special care of their marble, because it can be easily stained and etched by acidic compounds. There are many different forms of marble across the globe, and that is one of the reasons it has remained so popular throughout the years. Marble has an elegance that has passed the test of time. It was used throughout the ancient world because it was soft enough…

Concrete has been used since ancient times. Regular Roman concrete for example was made from volcanic ash (pozzolana), and hydrated lime. Roman concrete was superior to other concrete recipes (for example, those consisting of only sand and lime) used by other nations. Besides volcanic ash for making regular Roman concrete, brick dust can also be utilized. Besides regular Roman concrete, the Romans also invented hydraulic concrete, which they made from volcanic ash and clay. Concrete is the most…
