CONCRETE MIXING. INTRODUCTION. Concrete is a composite material usually made up of three main components: water, aggregate (fine and coarse aggregate) and Portland cement. Fine aggregates fill the spaces between the coarse aggregates while cement in the presence of water forms cementitious material, which binds the aggregates together. Concrete exists in two states, fresh concrete, and hardened concrete. The properties and characteristics of concrete are functions of the raw materials used as well as the mix proportions. CONCRETE MIX DESIGN Concrete mix design is used to achieve mixes on an empirical basis since it’s not possible to determine the strength of concrete correctly using properties and proportions of the mix components (Day 2003). Mix design ensures that the concrete bears the specified properties both in the fresh and hardened state. The weight ratio between water and cement is the most important design variable. Its ratio is referred to as a water /cement ratio (W/C). Typically, the w/c ratio should vary between 0.4-0.6 because excess water reduces the strength of concrete, and too low w/c ratio lowers the workability of concrete.…

Article Review:This is Water             “This is Water” by David Wallace is a speech that was given by Wallace during a graduation ceremony at Kenyon College in Gambier. The author uses emotional appeals and logical appeals to highlight the importance of thinking critically. In the speech “This is Water,” David uses the term “conscious” to refer to the people who think critically, and he uses the term “unconscious” to refer to the people who do not apply critical thinking while making their decisions. In the analysis between critical thinkers and uncritical thinkers, Wallace ignores possible ethical arguments that contribute to the societies where members think critically. “This is Water” is a commencement speech by Wallace that is concerned about how critical thinking affects day to day activities of individuals. The commencement speech “This is Water” by David Wallace starts with a story of two young fish that comes across to an older fish. The story of the fish is used by the author to illustrate the importance of critical thinking in daily activities. The older fish nods at the two…

8 TYPES OF WATER YOU SHOULD INCLUDE IN YOUR DIET.   Water is an essential component of our diet. That being said, they’re so so many infused water recipes that are essential for a specific set of outcomes. Here are some of the best-infused water recipes you should consider adding to your diet alongside their benefits. You might find some of these water recipes a bit grotesque or disgusting, but don’t worry, your interest should be on their long-term effect than how inaudible they are. Let’s dive in, shall we? Cucumber water. Add two thinly sliced cucumbers into a glass of water. You could add some ice and then fill the glass with water. Cucumber water provides extra vitamins and antioxidants, which help in preventing cell damage. You could also consider pairing the latter up with some fruit for some extra vitamins such as vitamin A and vitamin C, which is on top of the vitamin k that is present in the cucumber. Cucumber water also helps maintain steady blood pressure through the 4% DV of potassium, which is present…

RE: Value of Waterloo Alarm Corp (WAC) Investment From our visit to WAC and meeting with Julie Marino, we have assessed the following points for analysis as to the company’s worth and how much Julie Marino can be expected to pay for the company. Other points worth mentioning about WAC include: The accountant at WAC does not have any accreditation, which may affect the accuracy and valuation of accounts. Revenue recognition especially does not seem to comply with GAAP standards and thus the net worth of the company may be overstated. WAC’s customers are primarily composed of residential owners as opposed to commercial. This may limit the long-term growth potential of the company. Rex Sawyer, owner of WAC, has charged various personal expenses as well as provides salary to family members who do not work at the company. He has also stated that he gives out bonuses and dividends in accordance with what he thinks would be beneficial (eg. Staying under the small business limit for tax purposes). This may skew yearly comparability of the financial statements. We believe the…

Flint Water Crisis The above crisis took place when Dayne Walling was the mayor who together with other officials switched the drinking water of the city to the Flint River and toasted one another with the glasses of that water (Kennedy, 2016). The water pipes were corroded by the untreated water. This water was then channeled to flint homes and businesses for consumption. As a result, more than 100,000 people got exposed to high levels of lead. Some people knew that there was something wrong going on, however, their pleas were declined by the government officials who were at the state level. Most people were against the whole idea, in fact, one artist wrote a piece of opinion which was published in the Washington Post. Other several approaches should have been employed to curb the Flint crisis in a different manner (Canim, 2018). For an instance, other bodies apart from EPA should have been formed. This will help to foresee the work of the done by Flint in transforming the long-term source of water and replacing the lead service lines…

In this regard, management of operations is more technologically enriched as the compulsion to control the tech-oriented functions. The core focus of business is its profitability with reduced costs alongside its market success which remains dependent on the extent to which the management remains informed and up-to-date with trends and areas of impacting it. In this regard, it becomes quite important for an organisation to be well-informed of the areas that would potentially impact its growth. The…

drinking water, Boston Harbor and water reserve The various public, private and in between goods that are mentioned in this case study are drinking water, Boston Harbor and water reserve. Feasibility of exclusion is a term used to indicate how hard or easy it is to access to a good or service. In this case, the main good under discussion is drinking water. Unlike previous accessibility of municipal water, it is clear that the municipal water is difficult to access for the public use in Boston. This is as a result of increased fee for obtaining water from their well to obtain a fee to facilitate the cleaning of the sewage. This forced some people to opt for drilling private wells, to reduce the costs and making water more accessible to them. For instance, Legal Sea Foods, a Boston restaurant chain drilled its well which is capable of producing enough water to serve them as well as reducing $2,500 in one month cost compared to the fee paid for the municipal pool. By doing this, they are making water more…
