Concrete Research Paper

While the basic forms of Roman architecture were adapted from the surrounding past and present cultures, their innovation led to the advancement of these traditional ideals. The most notable advancement would be the invention of concrete to construct buildings. Composed of broken stones, flint, and sand, when this material became mixed with lime it created an amazingly durable and strong material known as concrete. With this, the newly developed material formed the core of most walls and ceilings of Roman structures. It is for this reason that concrete is the most significant Roman invention, "‘contributing more than any other material,' says Professor Middleton, ‘to make Rome the proverbially "eternal" city.'" (Walters, 23) Since the material was shaped by surrounding wood structures which could later be removed, the outer appearance of buildings became unattractive. To avoid this brick and marble were used as an outer shell of structures to conform to the beauty of surrounding Roman creations. The discovery of concrete and the efficiency of reusing the wood frames to construct buildings made architecture far quicker and easier than ever before. It is clear that "once the Romans had put the idea of using vaults and concrete together, the possibilities were endless." (Ramage, 53) Elaborate structures were now accessible, and the ability to erect enormous

Concrete floor is one of the most durable materials in the world. It can be made with waste products which help to reduce the consumption of valuable materials. It also can be made from fly ash, slag cement, and silica fume, all waste byproducts from steel mills, power plants and other manufacturing facilities.

On May 2, 2012, the National Football League lost one of its elite players to suicide: Junior Seau. Seau played for the Chargers, Dolphins, and the Patriots during his professional football career and was a 12-time Pro Bowler before retiring in 2009. Three years after his retirement however, Seau committed suicide by shooting himself in the chest with a gun. This greatly shocked the football world and its image of Junior Seau as a person, but it soon realized the cause for his action. Shortly after Seau’s death, researchers examined Seau’s brain and found that it contained a disease known as chronic traumatic encephalopathy which is formed

When reading of the concrete that the ancient Romans used, and learning of their unique mixture of volcanic ash and slaked lime (“pozzolana”) I find it most interesting that this concrete still proves to be standing in some places today! It is said to be less sturdy than what we use here in America (Andrews, 2012) but no doubt it gave modern civilization the ingenuity to create what we use today.

The following day, Coates returned to work with her notepad full of notes that she’d collected after studying Reno’s Facebook page. They’d been told that he and Savannah were madly in love, the next power couple, and had been dating for two years. They’d seen how he comforted Darlene, Savannah’s mother, at the crime scene. Coates’ experience had taught her that nothing is what it seems and Reno’s Facebook page corroborated her skills.

Concrete can be looked at as a material made from sand, gravel and cement. According to Lambert (2002), “the first major concrete users were the Egyptians in around 2,500 BC and the Romans from around 300 BC”. Roman concrete like modern concrete was an artificial building material made up of aggregate, binding agent and water. Aggregate could be gravel, chunks of stone, chunks of rubble, broken bricks, etc. Binding agent could be mud , lime or gypsum, mixed with rubbles stone. The Roman added pozzolona, a special volcanic dust found in central Italy (Archserve, n.d). The addition of pozzolona made the bond with the aggregate far stronger than what was traditionally being used. This development drastically changed and shaped construction work in the life of Rome.

Concrete was a recent invention which the Romans were still learning how to use. Not knowing exactly how strong the substance was the Romans

Since the start of last school year, I have probably poured a total of over one hundred cubic yards of concrete. Later on I will explain how to calculate what a cubic yard is, but for now, just know that concrete is no joke. Everyone involved must be focused at all times and if anyone fails to complete their job, then the entire pour could go downhill quickly. After reading this essay, I hope you learn to not only respect the amount of effort and work required to have a successful concrete pour but also to learn some of the basic things involved in concrete.

Miodownik is able to describe how the perception of people towards concrete has changed over the years. Concrete started off as being considered a modern material during the 1960’s to people wanting to cover up. “These days concrete is regarded as necessary, cheap, functional, gray, dreary, stained and most of all ugly,” Miodownik (69).

Concrete has many effects on the environment. Concrete damages topsoil which is the most fertile layer of soil. Concrete also contributes to surface runoff, erosion, and pollution. Concrete is helpful for preventing floods by building dams. I think that using concrete is good because while it does create runoff while used in roads it won't when used in a monument. And even though it damages soil it will not matter because their are no farms in the city.

If you go to Rome today you can see many ancient ruins that are still there because Romans used a ‘secret’ ingredient to stand their buildings. An example would be the Colosseum. In Rome, you can see that most of the Colosseum are still there, that’s because the Romans used cement when they made it. This proves that cement is strong and should be used in all

The Romans didn’t invent concrete however, it was how they mixed and what material they used in their concrete, that made it special. They used a material called pozzolana as the basis for the mixture. This chocolate colored material was essentially the ashes originating from volcanoes found near Greek settlements (Kamm, n.d.). With this new

The world needs heroes, but what really is a hero? A hero is someone who shows remarkable perseverance and courage. Perseverance means that you never give up and courage is when you are not afraid to do something. A hero should also be hard working which means they always do their best and does it diligently. Anyone who shows any of these qualities is a hero.

First, concrete durable. Concrete is something that will outlive other products up to three times over (“What Makes…”). In addition to durability, concrete is efficient. Concrete can be made with byproducts from power plants, and other aspects of manufacturing. Concrete is primarily made up limestone, the most abundant material on Earth. Above all of this concrete can be recycled. Concrete can be crushed and recycled into another structure or product, reducing the need to mine the limestone for production. Concrete also allows water to pass through which reduces the chance of flash flooding, erosion, and water table depletion as compared to other materials. This is a major check in the sustainability of concrete; the conservation of soil, landscape and ecosystems. Concrete is a very green option when it comes to building

Caving is where you can explore caves with special equipment and it is very safe. Some caves include waterfalls, tunnels, underground rivers, giant chambers, and all sorts of animals. Some caves have spiders, bats, bears, fish some times and other animals. For example, it is very important to have a source of light when exploring a dark cave. Cavers need to wear a well-fitted helmet with a headlamp. Back-ups for light sources, which can include extra batteries, flashlights, and glow sticks, are also important. Caves often get cold and can be very wet, so rugged, waterproof clothing, including sturdy hiking boots, is recommended. Other items to bring include enough food and water for the excursion, a small first aid kit, and a map of the cave. Some people prefer caving than hiking sometimes because they usually slip and fall in the
