Some of these factors are discussed in brief here. The energy consumption in India is also high and it is increasing many fold, say from 4. Because of requirement of thermal power generation and various other human activities, lots of Green House Gases GHG are produced.
Following are some of the main constituents of Green House Gases, which enter into atmosphere. In addition to these gases, Volatile organic compounds, asbestos, carbon monoxide, nitrogen dioxide NO2 , Sulfur Dioxide SO2 and combustion gases also affect air quality.
Some of these gases are introduced in the indoor environment also by paints, glues, solvents, wood preservatives, installation of carpets or through cleaning products. Effect of Global Warming Because of climate change, the air is getting warmer; summer comes sooner in most Continents including Europe and America. Mangrove forests of Sunderban in India, which are the unique islands and world's most prosperous group of Rainforest Islands, are likely to be wiped out from earth's map soon.
Now the threat of submerging is looming large on Sagardeep, the 4th biggest of the existing island. It is also on this Island, that the annual Mela of Gangasagar is held.
Sulfur Concrete for the Construction Industry: A Sustainable Development Approach [Abdel-Mohsen Mohamed, Maisa El Gamal] on zokeculromon.ga *FREE*. Sulfur construction materials include sulfur concrete and sulfur-extended Sulfur Concrete for the Construction Industry: A Sustainable Development Approach.
In general, the global warming may result in: Erratic sessions giving very hot or very cold climate Likely temperature rise Sea level rise - likely to rise by 0. An increase in heat waves Rise in tropical storm intensity. Erratic or Changed climate conditions. According to NASA satellite data, the Arctic Ocean could be nearly ice free soon, much faster than previous predictions.
Faster melting of ice there means eventual sea level rise and more immediate changes in winter weather because of less sea ice. Warmer oceans ultimately lead to more ice melting. Population Growth And Urbanization In , New York and few others were the only cities in the world with a population of more than 10 million. The number of cities with a population of more than 10 million increased to 5 in and above 20 in It is expected that this will increase to 25 or more cities by the year Currently, about one third of the worlds' population lives in urban areas.
The percentage of urban population in India was about Thus, a News Item: New Delhi, April 23 — By , Indian towns may turn dry, stinking hellholes, Dry taps, untreated sewage and piles of solid waste strewn all around.
The problem is much bigger, as less than 38 percent of the population, million people, in these cities may have access to sanitation facilities and 78 percent to clean drinking water. Thus, we need to act urgently for well being of its citizens and economy". Population growth coupled with urbanization results in significant impacts on the environment and many other related problems like: Deforestation. Deforestation is closely linked with negative environmental consequences such as loss of bio diversity, Global warming, Soil erosion and desertification.
This also lowers water table and flood volume increases. Deforestation also affects rain forest survival.
Excessive Waste Generation Huge amount of waste is generated every day in each Indian city and even rural areas. For example Delhi alone generates about tons of Garbage every day. By its amount may reach 1, tons. In the cities, the solid waste disposal areas are outside city which are miles away. Such amount of waste disposal is a Herculean task and needs space for dumping and fuel for transportation upto disposal areas. The central pollution Control Board estimates the current quantum of municipal solid waste generation in India to the tune of 50 million tons per annum.
Waste generation in major Indian cities generally range from 0. In addition, the hazardous waste generation is around 4. A typical solid waste dump is shown in figure 1. The granular sulfur The aggregates were natural crushed stones and the gradation of the aggregates was according to the ASTM Table 1. Also for the bitumen modified sulfur cement an emulsifying agent named triton X iso-octylphenoxy polyethoxy ethanol was used.
To obtain the sulfur cement the elemental sulfur and different percentages of the modifiers and the emulsifying agent for the bitumen modified cement have been mixed in a pot, and the pot was in an oil bath. Finishing the period the sulfur cement was achieved. Afterward the filler was added to the cement and then were mixed, next the mixture was added to the aggregates and got blended thoroughly Fig.
Also the vibration was done on a vibration table.
Blending the sulfur cement and the heated aggregates and achieving the sulfur concrete. The mixing of the sulfur and the modifier was done in two situations. For one series of the styrene modified concrete samples series 1 the opening of the pot was open and the vapors would exit Table 2 , and Fig. The mixing of the sulfur and the modifier in two situations a series 1, with the open opening of the pot b series 2, with the closed opening of the pot.
The modifiers were used with different proportions of the weight of cement sulfur plus modifier. Also different volumes of the triron X in proportion with different quantities of bitumen were utilized in the bitumen modified concrete.
