The article User:Dijuponnarambil has been speedily deleted from Wikipedia. This has been done under the criteria for speedy deletion, because the article seems to be blatant advertising which only promotes a company, product, group or service and which would need to be fundamentally rewritten in order to become an encyclopedia article. Please read the general criteria for speedy deletion, particularly item 11, as well as the guidelines on spam. Feel free to leave a note on my talk page if you have any questions about this.

Proposed deletion of SOLIDIFICATION AND STABILISATION TREATMENT FOR HAZARDOUS WASTE MANAGEMENT
A proposed deletion template has been added to the article SOLIDIFICATION AND STABILISATION TREATMENT FOR HAZARDOUS WASTE MANAGEMENT, suggesting that it be deleted according to the proposed deletion process. All contributions are appreciated, but this article may not satisfy Wikipedia's criteria for inclusion, and the deletion notice should explain why (see also "What Wikipedia is not" and Wikipedia's deletion policy). You may prevent the proposed deletion by removing the  notice, but please explain why you disagree with the proposed deletion in your edit summary or on its talk page.

Please consider improving the article to address the issues raised because even though removing the deletion notice will prevent deletion through the proposed deletion process, the article may still be deleted if it matches any of the speedy deletion criteria or it can be sent to Articles for Deletion, where it may be deleted if consensus to delete is reached. Do you want to opt out of receiving this notice? Triwbe (talk) 13:47, 31 May 2008 (UTC)

Nano-Engineered Concrete
INTRODUCTION

Nanotechnology is a powerful new technology for taking apart and reconstructing nature at the atomic and molecular level. It is being touted as the basis of the next industrial revolution and will be used to transform and construct a wide range of new materials, devices, technological systems and even living organisms. Nanotechnology deals with the production and application of physical, chemical and biological systems at scales ranging from a few nanometers to submicron dimensions. It also deals with the integration of the resulting nanostructures into larger systems. Nanotechnology also involves the investigation of matter to individual atoms.

One nanometre (nm) is one thousandth of a micrometer (μm), one millionth of a millimeter (mm) and one billionth of a meter (m).

Engineered nanoparticles are deliberately manufactured and can be distinguished from nanoparticles that ‘exist in nature’, or are by-products of other human activities. The properties of atoms and molecules are not governed by the same physical laws as larger objects or even larger particles, but by “quantum mechanics”. The physical and chemical properties of nanoparticles can therefore be quite different from those of larger particles of the same substance. Altered properties can include but are not limited to color, solubility, material strength, electrical conductivity, magnetic behavior, mobility (within the environment and within the human body), chemical reactivity and biological activity.

NANO-ENGINEERED CONCRETE

Nano-concrete is defined as a Concrete made with portland cement particles that are less than 500 nano-meters as the cementing agent. Currently cement particle sizes range from a few nano-meters to a maximum of about 100 micrometers. In the case of micro-cement the average particle size is reduced to 5 micrometers. An order of magnitude reduction is needed to produce nano-cement.


 * Self-cleaning concrete will not require the use of the solvents now used to clean buildings, eliminating another source of pollutants.
 * Clean concrete will reflect more light, reducing the heat buildup associated with “urban heat islands.” This may help keep our cities cooler during hot seasons.
 * It may also reduce the formation of smog since the chemical reaction that creates smog increases as air temperatures increase
 * Keep the building in new and clean view
 * Protect the surface from dust, acid rain and air pollutant damage
 * Purify the air pollutant near and on the surface (e.g. car exhausts NOx, Formaldehyde, Benzene, VOCs)
 * Restrain the dust electrostatic adsorption
 * Reduce the energy consumption for cooling the building in summer
 * Restrain mildew or alga growing
 * Make the surface without water stain after raining
 * Kill the bacteria and virus on the surface and in the air near the coated building
 * Absorb the UV from sun and then protect the surface from UV damage
 * Decompose the organic pollutant on the surface (e.g. oil, graffiti)
