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

Clay Bricks

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 The oldest discovered bricks, originally made from shaped mud and dating before 10000 BC, were found in Mesopotamia related to the first known cities.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

Bridges presentation

Foreword Bridging rivers, gorges, narrows, straits, and valleys always has played an important role in the history of human settlement. Since ancient times, bridges have been the most visible testimony of the noble craft of engineers. A bridge can be defined in many ways, but Andrea Palladio, the great 16th century Italian architect and engineer, hit on the essence of bridge building when he said "...bridges should befit the spirit of the community by exhibiting commodiousness, firmness, and delight." In more practical terms, he went on to explain that the way to avoid having the bridge carried away by the violence of water was to make the bridge without fixing any posts in the water. Since the beginning of time, the goal of bridge builders has been to create as wide a span as possible which is commodious, firm, and occasionally delightful. Spanning greater distances is a distinct measure of engineering prowess. In terms of engineering, b

PETROLEUM

Tallinn 2013 Ott Speek Subject: English Geodesy Study group: GI-21b PETROLEUM PRESENTATION Petroleum (L. petroleum, from Greek: Πέτρα (rock) + Latin: oleum (oil) is a naturally occurring flammable liquid consisting of a complex mixture of hydrocarbons of various molecular weights and other liquid organic compounds, that are found in geologic formations beneath the Earth's surface. The name Petroleum covers both naturally occurring unprocessed crude oils and petroleum products that are made up of refined crude oil. A fossil fuel, it is formed when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock and undergo intense heat and pressure. Petroleum is recovered mostly through oil drilling. This comes after the studies of structural geology (at the reservoir scale), sedimentary basin analysis, reservoir characterization (mainly in terms of porosity and permeable structures). It is refined and separated
