Using sewage sludge ash SSA as a substitute for part of cement in concrete provides environmental social and economic benefits with the aim of achieving basic sustainability principles

The main recycling and disposal routes for paper sludge are landspreading producing paper sludge ash or disposal to any river stream In function alternative paper sludge consists of cellulose fibres calcium carbonate and china clay and residual chemicals bound up with water To produce low cost concrete by replacing cement with hypo sludge

paper sludge fly ash The first one is to treat paper sludge fly ash with water to reduce the amount of free lime and at the same time increase the amount of portlandite that could be used to activate the pozzolanic reaction of metakaolin or at least reduce the water demand of paper sludge fly ash

Feb 17 2019 · Fly ash can be used as prime material in many cementbased products such as poured concrete concrete block and brick One of the most common uses of fly ash is in Portland cement concrete pavement or PCC pavement Road construction projects using PCC can use a great deal of concrete and substituting fly ash provides significant economic

Mar 20 2019 · However the alternatives for the established pozzolanic materials are necessary to extend the new types of byproducts or waste in RAC such as agricultural biomass or waste paper sludge ash Therefore this work aims to examine the potential application of waste paper sludge ash PSA as a type of mineral admixtures in RAC
