The modification of calcium sulfite in semi-dry desulfurization ash was studied. By the combining use of catalyst and oxidant, the content of calcium sulfite in the modified desulfurized ash was greatly reduced. In this way, the calcium oxide and calcium sulfate in the modified desulfurization ash were used to partially replace the lime, gypsum and other materials in the process of autoclaved brick production. The hydration reaction mechanism was discussed. Introduction It is common knowledge that sulfur dioxide is a main cause of acid rain. Removal of SO2 from flue gas emitted in the combustion of fossil fuels has been a worldwide concern since the 1970s [1]. To minimize the negative...

Copyright © 2013, Richard Ivey School of Business Foundation Version: 2013-12-19 In April 2013, Rajiv Sharma had a business plan. For quite some time, he had been doing some market research exploring the potential of his “dream project” — establishing a fly ash brick manufacturing unit — and had seen huge potential for profit in the project. His long-time friend Alok Gupta was also interested but had a few doubts regarding the feasibility of the project. Sharma, on the other hand, was sure of his plan. Years of work in the construction industry had shown him the potential of using large volumes of fly ash bricks in construction, especially in housing and infrastructure projects. On the basis of preliminary analysis, he decided to set up a plant that would have the capacity to manufacture four million bricks per year. Though actual production would depend on market demand, the partners estimated that 2.4 million bricks could...

The organization has developed it’s strategies, geographical focus, product mix and operational elements to regularly keep up with the changing market place and sustain it’s leading role. The restructuring of the organization has vastly improved performance. Grouping the cement and the concrete division under the same country manager instead of having two enables specific focus to the end consumer as well as cutting unnecessary internal costs. After organizational restructuring, the company changed it’s geographical focus going from the normal traditional structures in place in Asia, Middle East, Europe and North America, to new adaptable structures in emerging markets. This change included dividing operations into 3 regions, so that each center would be a mix of both emerging and developing – this way. Weaker markets could piggyback on the benefits of developed regions. This approach stemmed from the reality that emerging countries are driving sustainable needs for infrastructure and housing. Changing the product portfolio and market differentiation remained...

Dhananjay Sinha Co – Head, Institutional Research Economist and Strategist +91 22 6624 2435 dhananjay.sinha@emkayglobal.com 7 March, 2012 1 Difficult to deliver the perfect balance of growth and fiscal rectitude § Challenging backdrop: The backdrop for FY13 budget is challenging given the context of slowing growth, lack of investment momentum and a difficult fiscal scenario of subdued tax and non-tax revenue generation even while various subsidy burden are ballooning. Toping these is a much weaker Central government after recent state elections debacle of Congress party, which weaken its ability to take critical reform measures § Multiple priorities amid rising structural imbalances: Fiscal imbalances and falling domestic savings pose significant structural challenges. We will look for a credible commitment towards fiscal consolidation, ways to raise tax revenue (200bp hike in excise duty or expanding the tax base by including more services), reduction in subsidy burden by raising prices of public utilities and services, ways to address the recurring deficits across multiple public sector undertaking and departments and most importantly providing the focus on capital spending and infra sectors. While implementation of GST is most ideally suited in the current context we think it is unlikely to happen in this budget...

Both in disposal, as well as in utilization, utmost care has to be taken, to safeguard the interest of human life, wild life, and environment. FLY ASH FLY The combustion of powdered coal in thermal power plants produces fly ash. The high temperature of burning coal turns the clay minerals present in the coal powder into fused fine particles mainly comprising aluminium silicate. Fly ash produced thus possesses both ceramic and pozzolanic properties. When pulverised coal is burnt to generate heat, the residue contains 80 per cent fly ash and 20 per cent bottom ash. The ash is carried away by flue gas collected at economiser, air pre-heater and ESP hoppers. Clinker type ash collected in the water-impounded hopper below the boilers is called bottom ash. The World Bank has cautioned India that by 2015, disposal of coal ash would require 1000 square kilometres or one square metre of land per person. Since coal currently accounts for 70 per cent of power production in the country, the Bank has highlighted the need for new and innovative methods for reducing impacts on the environment. ...
