IN CONCRETE 2.3.4.1. WORKABILITY OF THE CONCRETE Fly ash particles are spherical in shape with high fineness and low carbon content this reduces the quantity of water required for a given slump (Zulu, 2014). This means that a mix with Portland cement would have a higher water content of the same workability compared to the fly ash mix. It is estimated that each 10% of fly ash added to a mix reduces the water content by 3%, this is dependent on the nature of the ash and other parameter of the…

1. What benefits have CEMEX and other global competitors in cement derived from globalization? More broadly, how can cross-border activities add value in an industry as apparently localized as cement? CEMEX and other global competitors in the cement market have definitely benefitted by being able to operate on an international level. An obvious advantage that CEMEX and quite frankly any vast corporation that reaches a global scale is diversification. Diversification has brought and brings…

Bias Decisions made at Deepwater Horizon To understand the decision-making biases that occurred with BP and Transocean one must begin to understand the magnitude of control BP had over the Transocean rig. Petroleum (BP), is a British multinational oil and gas company headquartered in London, England. It is a multi-billion company providing over 16,000 jobs in the United States. BP offers exploration for natural gas (BP, n.d.). The United States provides for nearly one-third of BP’s worldwide…

multivariate factors need to be deduced. These include; the location, the material of the steel and the characteristics of the cement mixture. Of the aforementioned factors, location is significant in informing Material Engineers regarding the type of environment in which the structure is built. The environment thus plays a pivotal role and governs the formation of cement and the type of steel utilised. In this scenario, the proximity of the bridge to the river enables us to infer the presence…

this decision using virtue ethics, first one points out qualities of a virtuous person. These would include honesty, loyalty, and selflessness. The virtuous person, in this case, would tell BP to spend the $128,000 and spend the time to conduct the cement test, so the safety of the rig and drilling operations can be confirmed. They would not allow BP to take the shortcut, because they would care about the workers on the rig before his/herself (Dr. Mason’s Virtue Ethics notes in…

from using a couple design procedure and also contacting a representative from Sika AG. (Designing and proportioning normal concrete mixtures). Using these sources, it was determined that the water to cement ratio would be 0.40. For self-consolidating concrete it is ideal to have a water to cement ratio between 0.38-0.42 in order…

to build a cement floor in a church that the villagers had long been working on. This project took up almost the entirety of the week, and while the work was immensely strenuous, it was strangely palatable, bordering even on enjoyable. Nonetheless, the process required dozens of hours of laborious man-power, and consisted of several steps. To create the floor of the church, our work consisted of hauling in dirt, pounding and leveling that dirt layer, and covering the surface with cement. Our…

slaves completed most of the activities. Among the outstanding events was there was the invention of concrete and cement, as well as the provision of running water to the city residents. Design of Concrete and Cement Most of the ancient Roman structures including the Pantheon and Coliseum are still available up to date. These structures strength is a result of the inventions of Roman cement and concrete. The engineers understood the importance of having such resources, and so they began…

morning not by the quake, but by a chunk of cement flying through his kitchen. Michael Beamer said he was eating breakfast before the earthquake began, and when it did he ducked and covered under his kitchen table. “I was eating my breakfast and the room started rolling. I dove under the table just as I heard an explosion outside and a chunk of cement flew through my kitchen window. That's when the screaming started across the street.” That “chunk of cement” came from McHenry’s Auto Supply…

Part One: Area of Philosophy In the event of the terrible accident on Hooper avenue, the doctors have done medical magic to save the person who was killed by the cement truck by transplanting their brain into the person of the opposite gender who had a stroke upon witnessing this event. While the mere act of even doing this type of transplant would fall under the philosophy branch of ethics, what we are talking about today my friends is what the result of this transplant and how would this…
