Transcript: Kevlar is used for protection, e.g bullet proof vests and motorcycle gloves. It is also used in bike wheels and for tires. Stephanie Kwolek first invented kevlar when she was working for DuPont trying to make a stronger tire. Advantages: It is incredibly strong It is light for how strong it is It is roughly of the same strength of glass but is less dense. Disadvantages: The fibres in kevlar make it more environmentally sensitive It is very difficult to cut. Its compressive strength is weak None of the disadvantages have any direct effects on the environment By Joe and Daniel Building Materials Stone Stone is very hard and rough in its natural form which makes it good for building houses with. Stone keeps the warmth in and keeps the heat in. Once stone is heated it stays heated for a long time. It keeps the warm in because it is so solid, which makes it a good insulator, because the heat can't escape through gaps in the wall. Advantages: Durable Unique appearance May be re-polished if scratched Disadvantages: Limited stain and chemical resistance On-going re-sealing is required. This material does not have an effect on the environment. Kevlar

Transcript: Hydraulic cement was introduced after the industrial revolution in 1824 by Joseph Aspidin. As we add H2O to Quicklime, Heat is released and Hydrated lime is the production. LIME CYCLE Air entrained: Facts TYPE OF CONCRETE (comparison) Hydrated lime (Slaked lime ) is a type of dry powder made from limestone. It is created by adding water to quicklime in order to turn oxides into hydroxides. Combined with water and sand or cement. Hydrated lime is most often used to make mortars and plasters. Its chemical name is calcium hydroxide or Ca (OH) Calcium compounds formed during the production of Portland cement Production proses of conctete concrete A promising new alternative to Portland cement has emerged over the past decade in the form of reactive magnesium cements, invented by Australian scientist John Harrison. The naturally occurring magnesium carbonate is heated to just 750 C and, more importantly, sets and hardens by taking carbon dioxide out of the atmosphere. THE VISET Limestone is calcium carbonate (CaCO3) which when turns into calcium oxide (CaO) “Quicklime” while releasing carbon dioxide (CO2). CEMENT Used for aesthetic reasons Used by reducing iron and manganese content More expensive than gray cement Has the same qualities as the grey cement Cement can be hydraulic (undergoes hydration) like Portland cement Or non-hydraulic like gypsum plaster. What happens when you apply water to the quicklime? Quicklime has many uses, Such as: Cement: Calcium oxide is a key ingredient for the process of making cement. Light: When quicklime is heated to 2,400 °C (4,350 °F), it emits an intense glow. This form is known as a limelight, and was used broadly in theatrical productions prior to the invention of electric lighting White Portland cement: Quick lime DR.RAHMA DOHEIM Hydrated Lime Limestone has numerous uses: as a building material, as aggregate for the base of roads, as white pigment or filler in products such as toothpaste or paints, and as a chemical feedstock. More types of cement … LIME Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). High calcium hydrated lime products normally are classified as Type N hydrates due to their poor water retention. Limestone makes up about 10% of the total volume of all sedimentary rocks. DONE BY: Types of Hydrated Lime: Building Materials Normal hydrated lime, products are only partially hydrated and have poor workability. Additional additives and long soak periods are required for these products to perform effectively in masonry applications. At least a 24 hour soak period is required before Type N dolomitic hydrate can be used acceptably for masonry applications. Type N ( normal ) hydrated Lime : Cement is a material that binds together solid bodies by hardening (aggregate) Achieved by air entrained chemicals To prevent expanding in cold or rainy weathers since cement is porous and absorbs water The amount of CO2 emitted by the cement industry is nearly 900 kg of CO2 for every 1000 kg of cement produced. LIME Green cement Type S (Special) hydrated Lime : Manufacturing of Portland cement Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline crystalline solid at room temperature. Types of Portland cement cement This new ‘green’ material is still very much at the research and development stage, but recent production trials of concrete blocks in the UK have made it a major step towards commercial reality. What happens when you heat the Limestone? Type S ( Special ) hydrated Lime : Portland cement type I : general purpose Portland cement type II :moderate sulfate resistance & low heat of hydration Portland cement type III: high early strength Portland cement type IV: low heat of hydration Portland cement type V :sulfate resistance Clinker is then mixed with gypsum Portland cement requires 4 main elements: Cement is used in Mortar(for binding blocks) and in concrete Limestone releases carbon dioxide forming quick lime(calcium oxide) then blended with other materials forming Clinker MASHAEL AL JEHANI ROUA BSOOKI Special hydrated lime products, are a combination of calcium and magnesium hydroxides. In building applications, Type S dolomitic hydrated lime products have high hydration levels and controlled plasticity (water retention). This allows for minimal soak periods prior to application. These products cannot entrain over 7% air Alite:Hydrates quickly, for initial set and early strength Belite: hydrates slowly , for later strength Celite: gives off heat , also for early strength Iron: reduce energy consumption and give the grey color Limestone is heated with other raw materials in a kiln at 1450 C (calcination) Carbon capturing cement: Green cement: The top three producers of cement are China India and USA for a combined total of over half the world total by the world's three most populated

Transcript: Building Furniture & Technology Building Materials Characteristics of Aggregates What is an aggregate? Aggregate, in building and construction, material used for mixing with cement, bitumen, lime, gypsum, or other adhesive to form concrete or mortar. The aggregate gives volume, stability, resistance to wear or erosion, and other desired physical properties to the finished product Aggregates Characteristics of Aggregates Characteristics of Aggregates Clean Solid Strong Well-graded Sharp/ Smooth Building Materials Stone based Concrete: this is a mixture of cement, sand, gravel, and water in specific proportions. Mortar: this is a miture of cement, sand and water in specific Proportions Definitions Batching: this is the proportioning of the ingredients when mixing concrete or mortar. This can be done in two methods: Batching by Volume Batching by Mass Batching Batching Batching by Volume: This method is usually carried out by using an open-bottomed box called a gauge box. For a 1:2:4 mix, the gauge box is filled once with cement, twice with sand and four times with gravel. Batching by Mass: This method involves the use of a scale which gives the exact mass of materials as they are placed on the scale. This is a better methodsince it has a greater accuracy. Mixing Mortar Mixing Concrete Short exercise Short Exercise Complete the following mixtures based on the ratios given. Example to be done together: Mixture of Concrete with 3 buckets (Gauge box) of cement 1. Mixture of concrete with 2 buckets of cement. 2. Mixture of mortar with 6 bucket of sand.

Transcript: First use of concrete by Romans in the town of Cosa after 273 BC. Roman concrete is found in The Roman Circus, The Roman Basilica, amphitheaters, and domes. Found in multi-story apartment blocks called insulaes, lighthouse in the Mediterranean, and temples like the pantheon. Bricks were found in old churches in the Mediterranean, Germany, and based off of their work there were bricks in Spain. Citations: DuTemple, Lesley A. The Pantheon.

Modern Comparisons: Thomas Jefferson designed Monticello after the Pantheon. Doric columns used in house architecture and on Justice Hall in New York City. Corinthian arches used in New York University and Duveen;s Gallary in New York city. The columns are used on the capitol building in D.C. Amphitheater is used in Michigan State's Football arena. The arch, vault, and the dome were unique features the Romans put into their architecture. Romans made concrete by mixing lime and volcanic rock to form a mortar. Concrete: Aqueducts Ancient Examples Frank Lloyd Wright used Roman brick in his design for the Robie House in Chicago"Frank Lloyd Wright Trust." Frederick C. Robie House.

Great with students, workers, family, etc. For example: With games like Jeopardy and Family Feud, players can pick practically any answers. The person who is running the game will have to have all of the answers in order to determine if players are correct or not. However, with a game like Who Wants to be a Millionaire, the players only have a choice between answers, A, B, C, or D. Therefore, when the player decides their answer, the person running the game clicks it, and the game will tell them whether they are right or wrong.
