UTILIZATION OF PAPER INDUSTRY EFFLUENT AS WATER REDUCING AGENT IN CONCRETE


ABSTRACT


The present paper describes the utilization of paper industry effluent as water reducing agent in concrete for its effects on various properties like slump, setting time, compressive strength etc. The properties have been compared with commercially available water reducing agents like modified lignosulphonate (MLS) and sulphonated naphthalene formaldehyde condensate (SNF). It has been observed from studies that th ....etc

The environmental impact of paper is significant, which has led to changes in industry and behaviour at both business and personal levels. With the use of modern technology such as the printing press and the highly mechanised harvesting of wood, disposable paper has become a cheap commodity. This has led to a high level of consumption and waste. With the rise in environmental awareness due to the lobbying by environmental organizations and with increased government regulation there is now a trend towards sustainability in the pulp and paper ind ....etc

Superplasticisers are high range water reducing admixtures. Admixture is defined as a material other than cement ,water and aggregate that is used as an ingredient of concrete and is added to the batch immediately before or during mixing. The development of superplasticisers is one the major break throughs in concrete technology, which will have a significant effect on the production and use of concrete in the next millennium. Superplasticisers have been greatly responsible for development of the following connects.
1) High performance connect ....etc

Sewage treatment is the process of removing contaminants from wastewater, primarily from household sewage. It includes physical, chemical, and biological processes to remove these contaminants and produce environmentally safe treated wastewater (or treated effluent). A by-product of sewage treatment is usually a semi-solid waste or slurry, called sewage sludge, that has to undergo further treatment before being suitable for disposal or land application.

Sewage treatment may also be referred to as wastewater treatment, although the latter is ....etc
