introduction of concrete as a construction medium and the true arch as a structural component made it possible for the Romans to build strong‚ elaborate‚ expansive structures that would endure the test of time. Concrete Roman concrete‚ called opus caementicium‚ was made by mixing traditional lime mortar with stone aggregate called caementa. This material used less water and was very thick compared to modern concrete; therefore it was laid rather than poured (Roman Architecture‚ n.d.). Concrete was an important

Ian Wendt August 17‚ 2011 Roman Pozzolanic Concrete The Roman Empire has contributed a wide variety of knowledge‚ ideas and technology to the world. These include novel concepts regarding the legal system‚ Roman numerals‚ architecture and the Roman calendar. However‚ the development of concrete as a building material is not the first thing that comes to mind when considering the Roman contributions to civilization. While the use of concrete predates the Roman era‚ the Romans discovered important

Introduction Concrete mixtures can be designed to provide a wide range of mechanical and durability properties to meet the design requirements of a structure. The compressive strength of concrete is the most common performances measure used by engineer in designing buildings and other structures. The compressive strength is measured by breaking concrete specimen in a compression-testing machine. The compressive strength is calculated from the failure load divided by the cross-sectional area resisting

1. INTRODUCTION Concrete is a widely used building material‚ many concrete pavements such as bridge deck‚ highway pavements and airfield runways are constructed all over the world‚ due to its superior properties such as high strength‚ good stability‚ abrasion resistance and anti-slippage. However‚ concrete is a poor electrical conductor‚ especially under dry conditions. Concrete that is excellent in both mechanical and electrical conductivity properties may have important applications in the electrical

The poem ’Concrete Angel’ by Martina Mcbride is a very strong and outspoken poem. This poem represents some of the large issues we deal with in our society today. The poem touches base with the children that struggle with abuse from their parents or other family members. Martina uses many symbolistic words that represent child abuse. Martina Mcbride is speaking in third person during this poem. She uses lines‚ such as‚ "but her dreams give her wings‚" to symbolize how the child is staying strong

to communicate the importance and the significance that Roman Concrete and the Roman Arch played in history. Both architectural elements would greatly impact the whole of the Roman Empire. Concrete; Since 25 B.C.‚ when Vitruvius wrote about the distinct types of aggregate for use in structural mortar in his “Ten Books of Architecture‚” Roman “pozzolana” or concrete quickly became the binding agent in Roman life. The advent of concrete could not be overstated‚ it touched every life in the Roman Empire
