This is a part of research on experimental investigations on utilization of waste foundry slag with alccofine in developing high strength concrete. In this research, the foundry slag is replaced in different proportions as fine aggregate and alccofine is used as a substitute for silica fume. This paper presents the results of an experimental study investigating the compressive, flexural and tensile strength properties of concrete using foundry slag as partial replacement for conventional fine aggregate. Samples of concrete (eg. cubes, cylinders, beams) were casted using varying contents of foundry slag as fine aggregate. The proportion of foundry slag was varied from 0% to 50% using concrete mix of M80 Grade and water/cement ratio of 0.274. …show more content…
This may leads to the problem of dumping industrial waste slag. Also slag obtained from smelting of scrap steel such as old cars may contain toxins and dioxins, which becomes hazardous to environment as well as human health. Although foundry slags have some desirable properties which makes it suitable for beneficial use. The proper and maximum use of waste foundry slag affects our economy and environment. Waste foundry slag consisting of silicates, alumino silicates and calcium alumina silicates which makes it a product that can be used as an aggregate in concrete and can be replaced as a natural conventional …show more content…
Since these waste materials are not useful and hence dumped as landfill near the industry. Unprocessed waste can result in environmental problem and waste disposal becomes a major issue. The effective utilization of this material can solve the environmental issue and can also affect the economy. This research was under taken to study the use of waste foundry slag as an alternative replacement material for fine aggregate in high strength concrete. As there is scarcity of conventional aggregates, it is useful to replace natural aggregates with waste foundry slag as it is a cheap material as compared to conventional aggregates and also saves water and energy in addition to reduction in green house gas emission. Foundry slag concrete is a green material and highly durable, it can be used to construct energy efficient buildings. Use of waste foundry slag in concrete may assist to attain LEED credits by green building council for new construction.
2.2 Scope of Study
In this research, concrete of M 80 grade was considered for a water cement ratio of 0.274 with a targeted slump of (190 ± 30) for replacement of 0%, 10%, 20%, 30%, 40% and 50% of fine aggregate with slag aggregate. These concrete mixes were studied for compressive, split tensile and flexure strengths.

First, prior to the start of the simulations, it is important that every team member reads the Team Member Guide at least once, preferably twice. The Guide includes all of the rules of the Capstone game such as sensor market description, industry conditions, segments that are available to target by teams and much more information. Moreover, the guide describes in details how to manage all four departments (Research & Development, Marketing, Production, and Finance). We recommend paying close attention to repositioning products depending on a chosen strategy in order to offer products that customers
Executive Summary Rock Solid Industry Parts, Inc. is a family owned company planning to move in a new direction to success. As a company moving towards a new direction employees need to change the way they work which represents the first challenge. After the leader of the company or CEO communicates the vision or goal with solutions to probable risks, employees should be able to apply the strategy accordingly in every department. Introduction/Thesis Rock Solid Industry Parts, Inc. is a small family owned company that is planning to grow from 50 to 100 employees in the next three years. In preparation for this goal the CEO consults the IT director of the options to modernize its IT/IS infrastructure.
The United States of America is one of the most technologically and industrially advanced nations in the world, but that was not always the case. At the start of the Civil War in 1861 the United States was little more than a nation of farmers, but by the time the Spanish-American war began in 1898 the country was one of the most advanced nations in the world. This begs the question, what exactly enabled the United States to be able to industrialize so quickly and efficiently? The industrial growth in the United States of America during the late 1800’s was caused by entrepreneurs, an evolving population, and government assistance.
In “Nuclear Waste” by Richard A. Muller, he expresses his concerns about radioactive material in Yucca Mountain that will be left behind for thousands of years and the unfamiliar dangers that we face. He starts by stating that nuclear waste is one of the biggest issues that our government faces even though they highly follow their “safe” nuclear waste disposal. He stresses how the government prototype nuclear waste facility at Yucca Mountain is supposed to be so safe, but they built it on a site that was created by volcanic activity. Scientist have contemplated many different ways to dispose of nuclear waste, but they all seem like the worse than their previous ideas and some still are considering more nuclear power. After his intense evaluation
There was a video that was released to the public that showed vast amounts of dead fish just floating on top the Clinch River and portrayed the high toxicity level of the river after it had received the runoff from the TVA spill. In response to the release of the video, the Tennessee Valley Authority took steps to stabilize the runoff. A spokesperson for the Tennessee Valley Authority stated that even though the river did have some trace of heavy metals that the coal fly ash slurry was not toxic and in terms of toxicity one cannot call it toxic until the final analysis comes in (XXX). An attorney with the Southern Environmental Law Center called the statement irresponsible and stated that coal fly ash slurry contains concentrated amounts of mercury, arsenic, and benzene. Local residents and environmental groups expressed concern that the fly ash slurry could become more dangerous once it dries out.
The Industrial Revolution was a point in the mid 1700’s where machine made goods were greatly increased in England. Women working in factories worked in outrageous working conditions, some even fatal. They had short breaks worked long hours and got little pay. The women that worked in the silk factories in Japan had all these cost, but they were just kind of worst. They not only had all this, but they also had unfair treatment.
Calorimetry 1 The purpose of this experiment is to identify the mystery metal given to us (metal A). We are going to identify the mystery metal by looking at both its physical properties as well as its heat capacity. The heat capacity of the metal will be calculated using a setup/method described below. We will also look at the physical properties of the metal such as its magnetic properties, density, whether it is lustrous or dull, etc.
WESTBURY, City - Firefighters and paramedics rushed to a chemical factory succeeding an explosion which left hundreds injured and 108 dead. The explosion occurred at noon destroying the facility and creating fires, which spread from the C shop to nearby buildings. A hazmat crew was brought to help clean the air and supply gas masks to anyone who was in the vicinity of the explosion.
Did you know that 1.4 trillion gallons were flushed into San Francisco Bay, in 2008 just to save the Delta Smelt? There have been restrictions on water. For this reason, farmers are not getting enough water to use for their crops. In my opinion, the water should be kept for the farmers to use.
There is no doubt that the great communication between Benin and Portuguese encouraged the Benin people to develop their brass casting. However, Benin didn't have enough metal for such development although its people were the inventors of the molding of copper and zinc as well as the brass casting. Thus, the Portuguese supplied Benin with brass ingots shaped as bracelets and they were called manillas. These brass manillas were made and used as currency by countries such as modern Holland where they were sent to Benin and melted by the Benin craftsmen. The quantities of brass manillas sent to Benin were huge.
