CHAPTER – 01- INTRODUCTION
1.1 GENERAL –
Red Mud is a hazardous waste generated in the Bayer process Alumina production (AL2O3) from Bauxite ore which contains high levels residual alkalinity and toxic heavy metal. Therefore, Red Mud is a hazardous waste of Alumina Industry. The volume of Red Mud which generated in the alumina processing plant depends on the quality of crude Bauxite ore, may be greater than the volume of alumina 1-1.5 times. The alumina processing plant usually disposes liquid Red Mud into reservoirs, which cause the risk of major environment pollution for lowland. The particle dimension of red mud usually less than 1mm . Therefore, dry red mud easy spread into the air and causes dust pollution. It is often exposured to dust cause skin and eyes diseases. Red mud in an liquid state causes harmful effect to human skin. Composition and properties of red mud in the world have been presented by many researchers in their publications.

Fly Ash is a byproduct of coal-fired electric generating plants. The coal is pulverized and blown into burning chamber for immediate combustion. Heavier ash particle (Bottom Ash or Slag) fall to the bottom burning chamber and the lighter ash (fly ash) fly out with exhaust gas, thus the term fly ash. Before leaving the stack, these fly ash particle are removed and collected by electrostatic precipitation, bag houses or other methods.

Abstract-
The Rivers form a city’s lifeline and no other city in the country can boast of having three Rivers running through it. Karha riverfront in Baramati City is a multifunctional riverfront with majority of premises being used as Residential, Irrigation,Indusrial Recreational purposes.

The water quality of the Karha River is very low due to a large amount of untreated sewage being let into the river. Other major problem pertaining to Karha river is flooding of the river.

The project work aims to carrying out suitable river-training works and measures to reduce the river pollution, restore and maintain the river ecosystem as well as riparian ecosystem.

The aim of this project would be transform Baramati as a unique cultural platform with recreational and entertainment facilities serving the city.

Abstract
This project deals with the statistical investigation of air quality and climatic change in chennai. The analysis ofambient air quality in chennai city employing Air Quality Index (AQI). An Air Quality Index has been proposed for the city of chennai for pubic information and data interpretation. The average concentration for four major parameters are taken into account (SO2,No,Co,PM2.5) for the year 2016-2017(present day) for specified location in chennai city is taken . The place is Alandur which is an industrialist area. The AQI is calculated using AQI procedure. It has been observed that the air quality before varadha cyclone is in satisfactory zone, whereas now, it has reached moderately polluted condition. The climatic change also varies from the past year to the present.

ABSTRACT:
The acoustical design issues for buildings involve the principal issues like site noise considerations. In any heavily populated area, there is enough activity going on at once during the day to generate all kinds of sounds across the audible spectrum of human hearing. Planes take off and land, traffic moves along roadways, construction crew repair roads, dogs bark, music blares, sirens sound, and lawns are mowed, etc.

The information contained in this article about library acoustics is intended as a source for these standards. As the architectural and engineering design of the project evolves, the design should be reviewed in light of the agreed upon acoustical programmatic requirements for the building project.

Underground Construction Techniques

CHAPTER 1
INTRODUCTION
1.1 GENERAL
The various underground construction methods discussed as options for the example facility must be evaluated on a site-specific basis, since factors such as site geology will vary significantly in different locales. The advantages and disadvantages of each option must be weighed, and each alternative’s costs and energy use must -be evaluated. The most effective options can .then be considered in terms of the various constraints posed by the individual site.

The article summarizes the challenges and considerations during planning, execution and commissioning of underground sections of metro. The work of fixing the alignment starts with fixing up the location of the station box, availability of the land in the close proximity of major origin/destination points or nodes which are dense passenger traffic junction is important. There are the instances when separate vacant land at these locations is not available, and in all such cases stations are planned below roads. Consideration of buildings nearby, no. of trees affected, possible traffic diversion, soil strata, utilities, access to the residents nearby are few points which are kept in mind the location of the station. Suitability from point of view of traffic integration is also a main criterion for fixing station locations. Stations are planned in such a way so as to be near established traffic interchange nodes so that they fit in the existing transport network and provide seamless intermodal transfer.
