Portland cement

On the site visit from 7th October there were many materials that were playing an important part in the development of the roadworks, including steel, concrete/cement and many more. Below I have selected three materials from the site visit and identified properties and uses. • Steel There are over 3000 different grades of steel all with unique physical and chemical properties. The production of steel is made in accordance with its application. Due to its high strength Steel is one of the most…

Introduction Although the Romans did not invent the arch, their development of it enabled them to support a large amount of weight and as a result to build larger and more glorified buildings. They wouldn’t be able to indulge, though, their architectural ambitions having not invented the concrete. Both concrete and the arch had a lasting impact on architecture throughout the world. This essay will examine the development of the concrete and arch, their importance of each in the life of Rome, as…

is the study of the interaction between people within their environment at a place. It includes three factors: space, place, and environment. In this paper, I will first explain what those three factors entail. Then, I will relate the factors to Portland in detail. Finally, I will discuss the research a geographer would need to produce knowledge by exploration and observation in regards to a city. The central concepts of geography are the space, place, and environment. The three factors make…

“What makes someone a trail blazer?” This question was posed to me by my mother when advised to expand my ideas when writing my essay. “What defines a trail blazer?” A trailblazer is defined as a pioneer and innovator. I was astonished to find that a word that is so influential to me would have two unstimulating words as its definition. So, I posed the question to myself “What makes me a trail blazer?”. My thoughts are a trail blazer is someone who creates their own pathway to success, while…

United States, so I planned to go to school as my second purpose. Although I came to the United States as a chaperon for my child, the result that I came across a good college and considerate people in Portland stimulates my curiosity about education, I take delight in studying education at Portland community College (PCC). The heart of my issue before I moved to the United States was where I should live. I couldn’t decide the best place to live just because of a famous city. Unlike a summer…

Grout or cement is a popular choice. The cement is spread over the soil and then it is mixed together with heavy machinery. The mixing process continues until the desired condition of the soil is achieved. After that, the area is graded and prepped for construction just like any other patch of soil. Soil Stabilization Adds Strength The new soil mixture is compacted to prepare the base for your new parking lot. With cement added, the mixture is dense and strong.…

There are several different varieties of post-secondary schools for education and experience. A more logical choice would be to stay in one’s own state to attend a post-secondary school due to the fact it is closer to one’s own home and is often cheaper for instate residents. However, this is not always the case. Therefore, I have chosen to research an out-of-state university under the belief that it suits me the best. The following essay will detail the information that has been researched when…

Result 4.1 Experimental Analysis The experimental work is carried out to evaluate the shear strength of steel fiber reinforced concrete deep beams without stirrups. For this 18 beams are cast. The beams are tested under two-point loading as per IS after 28 days curing. Fiber fraction is varied as 0%, 1.5% and 3%. The shear span-to-depth ratio (a/d ratio) for beams is kept as 0.60 for case-I and 0.74 for case-II. The cube compressive strength is estimated. The experimental results are…

Visual Observation Dry Texture Test Wet Texture/ Rolling Test Smear Test Nutrients Quickness of drying Sand Particles visible with eye. The heaviest. Feels gritty and falls apart Crumbles No smear Few nutrients Dries quickly Does not hold water well Silt Just enough big to see them with a magnifying glass. Not as heavy as sand but heavier than clay Holds together, feels smooth and powdery Holds together, moderate crumbling, cannot be rolled in a strand Some smear More nutrients than sand Takes a…
