Some of them of the great things that they have built include; concrete‚ roads and arches. With these inventions and several more‚ the Romans have changed the art of buildings for ever. Without it the world would not be the same‚ and it would affect our world forever. One of the first inventions that the Romans made‚ was concrete. Concrete was used to be made as a glue like substance for building structures. The Roman concrete was made of lime‚ seawater and volcanic ash. According to the Article

Non-destructive Testing Of Concrete By Rebound Hammer By Kaushal Kishore Materials Engineer‚ Roorkee INTRODUCTION The standard method of determining strength of hardened concrete consists of testing concrete cubes in compression. The quality of entire concrete of a structure cannot be fully assessed by testing a few concrete cubes. The results obtained in testing cubes do not always reflect the actual strength of concrete in construction. In a whole day‚ concreting work cubes are cast in

had been famous for being the first concrete buildings as the Romans were who invent the concrete. Also‚ they were famous for their applying to the arches in a wide range. Thus‚ I will discuss the importance of those two important factors‚ the arches and the concrete and their development. Also‚ I will discuss the results of their use. The Roman buildings were built with a special concrete‚ unlike the concrete that we use in these days. That type of concrete was made from pozzolana‚ a dark material

Title no. 106-S64 TECHNICAL PAPER A Practical Equation for Elastic Modulus of Concrete by Takafumi Noguchi‚ Fuminori Tomosawa‚ Kamran M. Nemati‚ Bernardino M. Chiaia‚ and Alessandro P. Fantilli Many empirical equations for predicting the modulus of elasticity as a function of compressive strength can be found in the current literature. They are obtained from experiments performed on a restricted number of concrete specimens subjected to uniaxial compression. Thus‚ the existing equations cannot

Executive Summary Throughout the years there has been an increase in strategic alliance formation in order to combat a number of factors creating uncertainty in the market and to share knowledge and know-how. The formation of alliances has also occurred in the Airline industry; this report discussed how these alliances gain economies of scales and synergies. The deregulation of the airline industry has open doors to more competition sand to further agreements such as the “open skies”‚ these agreements

10 years Star Alliance from “The airline network for Earth” to “The way the Earth connects” . When the Star Alliance network was founded in 1997 it was the right idea at the right time. Globalisation had started to change the business world and the needs of business travellers from the ground up. The founders of Star Alliance responded by creating an airline alliance‚ which was the first of its kind and still is the most successful in every respect. Usually the world advances in small steps.
