Modern Day Concrete Research Paper

After perfecting the formula for this concrete, they had achieved a cement that could help construct durable buildings. By laying the concrete between bricks and then covering the facade of the building with marble slabs, the Romans made well constructed buildings that gave the appearance of pure marble (Connolly).

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.

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.

I wanted to become a cement mason because I love working with my hands and learning new things and bringing them to life. To become a cement mason, I recommend you have good hand skills and upper body strength and be very persistent with your work. When I was younger I always saw men working on the side of the streets and highways around my city with these big trucks. I always wanted to know what they were doing and what was in the back of the trucks.

Although concrete curbs provide a finished, attractive look to streets, driveways and parking lots, they also offer a variety of useful functions. They can prevent vegetation from encroaching upon the pavement, discourage parking or driving on lawns and sidewalks, channel runoff efficiently to storm drains and delineate property boundaries.

This report provides an analysis and evaluation of the current and forecasted profitability, liquidity and financial stability of Alliance Concrete. Methods of analysis include forecasting the income statement and balance sheet to calculate financial ratios and profitability ratios. The key drivers for the income statement was management’s assumption about the sales environment surrounding Alliance Concrete. All calculations can be found on the attached document. Results of data analyzed show that Alliance Concrete is experiencing sales decline, profitability decline, but is relatively financially stable for the most part. The report finds the prospects of the company in its current

In this quotation from the author Vitruvius, he explains the process and creation of concrete, emphasizes on its durability and how it can withhold the forces of nature. This new formula had a higher silica content then before, which essentially allowed to concrete to set under water and made it stronger then before.10 Overall, the use of concrete was crucial to construction in ancient Rome because it was extremely durable compared to other materials such as brick, stone, or wood.11 Having a successful and powerful empire was very important to the Roman’s as they believed that without a strong foundation, a strong empire would not be possible.12

The history of cement itself goes back thousands of years. The first sign of cement use comes from the Egyptians, with the use of lime as the “calcareous adhesive”, which they burnt and powdered and can be found cementing the pyramids together still. The Greeks were the next to use lime mortar, “prepared much as it is prepared today.” They also found that certain volcanic deposits combined with water gave increased strength and durability to the mortar. This technological advance was copied by the Romans who were able to make an “admirable hydraulic cement” as they saw constructing a building out

Concrete is known for being an enticing building material because of its economic availability. While steel and wood can be expensive, reinforced concrete has consistently proven to be cheaper and efficient. When forms go beyond rigid structure, reinforced concrete provides the next level of opportunities blurring the line between structure and architecture. This gray zone is where the capabilities of structural art falls. Within reinforced concrete building, pre-fabricated systems link the desire to economically create sculptural design that continues a relationship with classical architecture. Reinforced concrete holds the potential to bridge the expressiveness of design with the functionality of monumentality.

To deliver a sustainable built environment, concrete plays a crucial part in performance of the structure’s durability, robustness, fire-resistance, thermal mass, acoustic performance, and flood resilience. It is now days recognized and utilized by various design teams in the delivery of different sustainable projects.

Infrastructure development across the world created demand for construction materials. Concrete is the most important construction material. Concrete is a mixture of various ingredients like aggregates, water and admixture. Aggregate form is the major part of concrete among the entire ingredients used in concrete. The use of normal weight of aggregate such as gravel and granite probably reduces the natural stone deposits and it cause effect on environment. Therefore, it is necessary to explore and to find out suitable material for the replacement and to substitute the natural stone. In foreign countries, the natural and artificial light weight aggregate has been identified

According to ASTM and ACI committee, concrete is defined as a composite material that consists essentially of a binding medium within which are embedded particles or fragments of aggregate. But Hansen suggested that a composite material can have two fundamentally different structures. The first one is an ideal composite hard material, which has a continuous lattice of an elastic phase with a high modulus of elasticity, with embedded particles of a lower modulus of elasticity. The second type of structure is that of an ideal composite soft material, which has elastic particles with a high modulus of elasticity embedded in a continuous matrix phase with a lower modulus of elasticity. (Neville, et al., 1983). Concrete being a composite material can thus be considered as consisting of two phases: hydrated cement paste and aggregates, and the properties

Cement is a fine, soft, powdery-type substance. Concrete is a fine, delicate, fine sort substance. It is produced using a blend of components that are found in natural raw materials, for example, limestone, mud, sand and/or shale. At the point when cement is blended with water, it can tie sand and rock into a hard, strong mass called concrete. Cement is a binder, a utilized as a part of construction that sets and hard and can bind tie different materials together. The most important types of cement are utilized as a segment as a part of the generation of mortar in masonry, and of concrete, which is a blend of cement and an aggregate to frame a solid building material. Cement is usually grey. White cement can also be found but it is typically more costly than grey cement.

With the continuous improvement of modern architectural functions, higher requirements of concrete have been put forward. Under the circumstance of high technology, concrete technology is developed towards high-strength, high-workability and high durability. Since the 1990s, along with a variety of new cementitious materials, mineral admixtures, superplasticizer and the new development and application of other additives, the production of concrete with good workability, excellent mechanical properties and also high durability can become a reality (Laskar, 2011). This new type of concrete is called high-performance concrete (HPC). Compared to the conventional concrete, HPC has high strength, high resistance and high durability. Therefore, high-performance concrete is the inevitable result of the development of modern concrete technology.
