    1.0 INTRODUCTION 1.1 CONCRETE: Concrete is a composite material formed by combination of cement, fine aggregates, coarse aggregate and water together in a suitable proportion. This mix form easily workable paste known as plastic wet or green concrete. After mixing and placing the concrete in position the cement and water undergoes hardening, the cement paste in this way bind the aggregate like hard mass, which is called concrete. Now a days concrete is used most commonly as a building material because

  • How Did Greek Architecture Influence Roman Architecture

    1571 Words  | 7 Pages

    The ancient Romans have left a grand mark in history, and their inventions shaped the course of human development, which can still be seen in society today. Much like their ever-reaching empire, the influence of Rome is evident in many fields, such as mathematics, medical science, and engineering. The Roman numeral system withstood the test of time as it is still mainly used to aid in calculations, and is commonly used in titles and popular references. The creation of our own Gregorian calendar is

  • The Famous Pozzolana Cement Of Ancient Rome Came From The Mining Of Volcanic Ash

    1002 Words  | 5 Pages

    of ancient Rome came from the mining of Volcanic Ash, which was abundant in aluminosilicate minerals. (Lea, 2015) This specific cement, or indeed any aluminosilicate that react with lime in water to form cement is still referred to as Pozzolana or Pozzolan. In 1756 in Devon, John Smeaton developed a hydraulic lime which would go on to be succeeded by Portland cement (Milana, 2011). Further progress took place throughout the 1800s, but the actual concept of Portland Cement can be dated back to England
