Durability of concrete In this presentation I'm focusing on the durability of concrete. First I'll give a brief overview of concrete, we have to know what does it actually means and where is it used? (slide) Basically concrete is a construction material composed of cement, aggregate (generally gravel, limestone, or granite, plus a fine aggregate such as sand) also water, and chemical admixtures.(slide) Concrete is used to make pavements, architectural structures, foundations, roads, bridges, marine- and parking structures, brick/block walls and footings for gates, fences and so forth. Mainly it is used because of its high durability and availability, but also because it is cheaper than to use wood for example. Concrete is used more than any other man-made material in the world.(slide) Moving on, the durability of concrete can be defined as the ability to remain serviceable for at least the required lifetime of the structure of which it forms apar
Introduction (slide 2) In this presentation I'd like to give a brief overview of clay bricks. I'll speak about 15min to allow time for questions at the end. Firstly clay bricks are known for centuries as one of the most solid and reliable structural elements is set to play a role in reducing global warming. Apart form the many benefits obtained from using clay bricks in construction, such as their durability, insulation properties and aesthetic qualities, recent findings show that they also produce less carbon emissions than any other masonry material. History (slide 3) In more detail the earliest bricks were dried bricks, meaning they were formed from clay- bearing earth or mud and dried usually in the sun until they were strong enough for use. The oldest discovered bricks, originally made from shaped mud and dating before 10000 BC, were found in Mesopotamia related to the first known cities. Ceramic or fired bricks were first introduced by the Romans. These were mainly flat, broad

The variables investigated were flow rate inside a submerged helical coil and agitation of the bath. To investigate the change in heat transfer coefficient in different situations, a simple experiment was set up. It consisted of a rectangular isolated tank, which was filled with water, submerged ste
