Most of the people with whom we spoke, however, attribute these surface problems to contractors unfamiliar with finishing properties of GGBF slag concrete. Re-naming and. They didn't waste any time making the change. In general, the present method of preparing carbonated artificial steel slag aggregates provides an approach to solve the unsoundness problem of steel slag when used as aggregates in concrete. Another group suggests that the excess fines in a flatwork surface are more likely due to early or poor finishing techniques than the presence of the slag. Many adjust the yield by reducing the fine aggregate (sand). There are very few major advantages or disadvantages to using slag cement. Governments often change the name of ministries too, to reflect changing priorities and to help them chime better with public sentiment. cement.ca. To achieve this goal in concrete pavement, various substitutes were found to be replaced with natural aggregates of concrete. Qualitative research would involve both interviews (for example with CEOs) and focus groups (for example with science students or employees). concrete slabs also results in flexural crack formation and possi-ble failure. Iron slag is one of the industrial by-product from the iron and steel making industries. Les cendres volantes et le laitier de haut fourneau peuvent aussi améliorer la malléabilité du mélange de béton et atténuer les éventuels problèmes de réaction alcali-silice. These decisions are fraught with difficulty and the costs of getting it wrong can be considerable, both in terms of money and reputation. The only potential problem with steel slag aggregate is its expansive characteristics and undesirable reactions between slag and components of concrete. Would the epitome of all-American masculinity, John Wayne, have succeeded as the metrosexually-named Marion Morrison? In English-speaking countries, 'a slag' is a promiscuous woman, whilst to 'slag someone off' is to criticise them in an abusive and insulting manner. Due to industrialization enormous by-products are produced and to utilize these by- products is the main challenge faced in India. Considering both the mechanical performance and the volume stability of aggregates, the mix proportion of S60F30 was the best formulation for the preparation of carbonated steel slag aggregates … Fly ash and blast furnace slag also increase the workability of concrete mixtures and can be used to mitigate potential alkali aggregate reactivity problems. A finisher used to working with a 100% portland cement mix must be warned that a mix containing GGBF slag may require a slightly longer set time and that there will be a little less bleeding. Negative associations - to which names can contribute - are likely to impact an industry in many ways. Air-cured concrete had higher scaling resistance than concrete cured with commercial curing compounds. 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. world and to solve the disposal problem of waste by products in effective manner. With the perjorative connotations of the word 'slag' in mind, delegates at the 6th Global Slag Conference, held in November 2010 in Sydney, were asked to propose alternative names for slag. Contrary to the assumptions of modern economics, people do not have access to perfect information when they make decisions and nor do they always make rational choices: Investment bubbles are testament to these facts. Once a short-list of options has been drawn up, quantitative research could help provide a final check and determine the 'winner.'. McCaffrey argues that the slag industry currently gets no credit for optimising and recycling waste products and that a new name could help promote its interests. cement.ca. In a word, 'No.' 2. An air-cooled blast furnace slag did not present problems of heavy metals leaching. The applications of steel slag powder and steel slag aggregate in ultra-high performance concrete (UHPC) were investigated by determining the fluidity, nonevaporable water content, and pore structure of paste and the compressive strength of concrete and by observing the morphologies of hardened paste and the concrete fracture surface.
