In this study, paper sludge ash, a waste from pulp and paper industry was used as a filler in fabricating Plaster of Paris/paper sludge ash composites. Various percentage of paper sludge ash was used, namely 1wt.%, 3wt.%, 5wt.% and 7wt.%. The effect of paper sludge ash on the compressive strength of the Plaster of Paris was studied. The mixed powder of paper sludge ash and Plaster of Paris
SEM and EDX Analysis of Waste Paper Sludge Ash and Cement R. Murugaboopathy Lecturer, Civil Engineering, Ramasamy Raja Polytechnic College, Rajapalayam, Tamil Nadu, India ABSTRACT In Sivakasi, India, large volume of paper sludge is discharging from paper mill daily. These discarded paper sludge is clogging the pores of the land, when it is
Waste paper sludge is waste product of paper industry, during manufacturing of paper white mud comes out during the process is called paper sludge or hypo sludge or brine sludge. This project is based on the viability of use of waste paper sludge,
This paper presents a study evaluating the use of sludge ash as a stabilizing additive to soilcement mixtures for use in base and subbase road pavements by
A method for making an animal bedding fiber product, the method includes providing fiber from paper sludge, formulating the fiber in a mixture including a first desiccant agent including ash, so as to form a friable aggregate. Further, a fiber product including at least one short paper fiber from a secondary fiber, one or more inorganic fillers including kaolin clay; and a first desiccant
sludge ash and to reduce disposal and pollution problems due to waste paper sludge ash. The innovative use of waste paper sludge ash in concrete as a supplementary cementitious material was tested as an alternative to fibre reinforced concrete. In this study waste paper sludge ash was partially replaced from 5%, 10%, 15% in cement to get
#0183;#32;Accordingly, chemical compositions of waste paper ash were investigated and cement was replaced by waste paper ash in a range of 0%, 5%, 10%, 15%, and 20%. To examine the suitability of paper ash for concrete production, its effect on both fresh and hardened properties of C
The cement has been replaced by fly ash and hypo sludge accordingly in the range of 0% (without fly ash and hypo sludge), 10%, 20%, 30% amp; 40% by weight of cement for M25 and M40 mix. Concrete mixtures were produced, tested and compared in terms of modulus of elasticity with the conventional concrete for 56 days water curing.
With the addition of waste paper sludge, there was a slight reduction in the workability. REFERENCES [1].Sajad mad, Malik, Muzaffar Bashir Wani and Rafiq mad, Study on concrete involving use of Waste paper sludge ash as partial replacement of cement, IOSRJEN,, Issue 11,
In Italy, about 600,000 t of paper mill sludge is produced yearly. About 6 kg of sludge is produced per ton of paper produced. The paper mill sludge is recovered from a primary mechanical separation process. When it is combusted as a single fuel source, it produces paper mill sludge ash (PA).

An object of the present invention is to provide a method for effectively and simply treating paper sludge combustion ash containing harmful substances. According to the present invention, there is provided a method for treating combustion ash, comprising adding and kneading 6 to 13 parts by weight of aluminum sulfate to 100 parts by weight of combustion ash containing paper sludge combustion
Many researchers have inve stigated about the potential uses of paper sludge ash in constr uction industry, cement manufacturing c ompany, ceramic and glass prod uction etc. Honeycutt et al
In Italy about 6x10 5 tons of paper sludge is yearly produced giving 60kg of paper ash per ton. In this project, the ash coming from burning of paper mill sludge from primary mechanical separation process, fired as single fuel, was studied in order to evaluate its use as supplementary cementitious material in concrete manufacturing.
#0183;#32;Waste Paper Sludge Ash (WPSA) is a waste material collected from the Paper Industry. WPSA is used as cement replacement in producing mortar and was investigated on its chemical, physical and mechanical properties. Construction material with natural resources now become limited and causes of air pollution and environmental problems.
The largescale production of cement is causing environmental problems and also depletion of natural resources. This research work demonstrated the possibilities of using waste paper sludge ash as partial replacement of cement in concrete. An uncontrolled combustion process was used to obtain waste paper sludge ash (WPSA) as an admixture to ordinary portland cement of grade M43 and M53 in...
