The document summarizes the reclamation of a former steelworks site in Ebbw Vale, Wales. It discusses the constraints of the site including past mining activities that led to ground instability and contamination. Shallow mine workings and entries were mapped, and contamination from past industrial uses such as coking ovens and gas works was identified. Remediation efforts included bioremediation of hydrocarbon contaminated soils, treatment of mine entries, demolition of basements, and soil forming to reclaim the land. The goal of the reclamation project was to make the post-industrial site safe and suitable for redevelopment.
This presentation covers the chemical constituents of Portland cement (PC) and the effects and properties of each of the main and minor compounds that make up the (PC). Their typical ranges in PC and in various types of PC. (edited)

Method of cement manufacturing & during manufacturing different type pollute-net material like as dust ,CO2,SO2,CO occurs. So this PPT helpful to understand type of cement manufacturing like as wet / dry process & maintain environmental conditions by using EPS, wet scrubber ,cyclone separator, gravitational settling chamber on site.
Popular as Building material.
Material with adhesive and cohesive properties.
To bind the fine and corse aggregate together.
Common variety of cement is known as the Portland cement.
India is the fifth largest producer of cement in the world.
Rajasthan is the second largest producer of cement in india after Andra Pradesh.

When coal exposes to air it undergoes Oxidation which gives out various gases such as carbon monoxide, methane etc. along with the evaluation of heat. the reaction takes place even at normal atmospheric temperature but when the temperature and the heat evolved reached ignition temperature of coal, coal catches fire.

9. Contamination
• Site investigation has identified a series
of contamination ‘hot spots’ throughout
the site.
• In particular these relate to elevated
metals and hydrocarbon contamination.
16. Mine Entries
• On basis of The Coal Authority and
initial investigations 5 mine adits
and 14 mine shafts are recorded at the
site
