Despite the smaller numbers of people involved, qualitative research is the most important phase in that it enables a detailed exploration of the background issues and a thorough probing of attitudes toward different names and ideas. Companies give much thought to the names of brands that they own. Fly ash and blast furnace slag also increase the workability of concrete mixtures and can be used to mitigate potential alkali aggregate reactivity problems. Most of the people with whom we spoke, however, attribute these surface problems to contractors unfamiliar with finishing properties of GGBF slag concrete. With CO2 emissions, Global warming and the remorseless pressure that humanity is placing on Planet Earth never far from newspaper front pages and high on the political agenda, the slag industry has never had a better moment to leave behind its past and re-position itself for a better future. However, the word also has other meanings in the popular vernacular. re-branding is common in government and politics too. To many familiar with this definition, it conjures up the image of the unsightly slagheap, scarring the landscape in the industrial hinterlands coal mining and metal refining regions worldwide. Setting Time The setting time of concrete … It is a waste product, a leftover that no-one wants. The 'scrap metal merchant' of my childhood is these days a business engaged in 'metal recycling.' The wrong choice can invite lawsuits (Apple Corps vs. Apple Computers), general derision (Ford's Pinto model was always going to have a tough time in Brazil, a Portuguese-speaking country, where pinto is a slang word meaning penis) or a consumer backlash (The Royal Mail in the UK provoked a public outcry when it ditched its heritage in favour of the contrived 'Consignia' name. We contacted a sales engineer at a GGBF slag supplier. It would need to work internationally, be short, memorable and ownable. In our area, people are discussing the benefits or disadvantages of finishing exterior concrete containing ground granulated blast furnace (GGBF) slag. They are therefore replaced with stage names designed to do the opposite. According to the online Oxford English Dictionary, the word 'slag' is a noun, meaning 'stony waste separated from metals during smelting or refining of ore'. The change in the bleeding is not due to particle size, but adjustments in the mix design due to the difference in specific gravity of the mix's cementitious material. Cracking in concrete can be reduced significantly or eliminated by observing the following practices: 1. Mobile secondary crushing … In the case of slag, a new name would need to break with the negative associations of the past and re-cast the slag industry in a more positive light, ideally communicating both its high-tech nature and its environmental credentials. may result in aesthetic, functional, or structural problems. It might also be desirable, for example, for subtle variations on a new name to communicate different product streams. Independent operating combined mobile crushing station . Steel slag was used in conventional concrete to improve its mechanical, physical, and chemical properties. For slag, appendix of 989 (Specification for Ground Granulated Blast-Furnace Slag for Use in Concrete and Mortars) (ASTM, 1993) suggests using either the 0.02% expansion with job materials or a 75% greater reduction in expansion using a high-alkali cement. Researching alternative names does not guarantee success, but it does improve the odds, which is why large FMCG companies invest so much on such research. Due to industrialization enormous by-products are produced and to utilize these by- products is the main challenge faced in India. The word slag orginates from the medieval German word 'slagge', meaning 'to strike, with reference to the fragments produced by hammering or forging metal' (Chambers Dictionary of Etymology). It was eventually forced into an embarrassing and costly retreat). Chemical analysis is also observed to understand the effect of aging process in steel slag aggregate. As David Hume, that great Enlightenment philosopher and famous empiricist put it, 'Reason is...slave of the passions and can never pretend to any other office than to serve and obey them.'. Who is right? As soon as molten 'slag' is modified in any way (including its composition, mineralogy and cooling history), it would cease to be 'slag' and would become a product (after all, any intervention costs something). The one critical factor to be understood was that the term 'slag' would still be used in the industry, but solely as a term for a molten mass.
