The results showed 4.58% reduction in dry weight of concrete cube specimens for concrete mix with 20% waste paper sludge ash content as compared to reference mix.This reduction in density can be attributed to lesser specific gravity of waste paper sludge ash as compared to cement. Thus, waste paper sludge ash concrete is light weight in nature.
3.1. Paper Sludge Ash Paper Sludge ash (Fig.3.1) is the waste product obtained in the manufacture of paper from the paper mill industry. It imposes a major economic and environmental crisis in Paper and board industry as it's a waste product and imposes difficulty in dumping. Paper sludge is currently in use as an alternative fuel.
ash was detected during paper mill sludge and wood firing suggesting that the fraction of the volatilized inorganic species in the paper mill sludges was low. Results from pulp mill sludge and bark co-firing were different. This fuel mixture produced a clear mass mode below 0.3 µm, presenting 2.2-5.0 weight-% ...
In the effort to produce sustainable concrete, considerable attempt has been placed on replacing the main ingredients in concrete mixtures with more sustainable materials with the objective to reduce the carbon footprint.

In this thesis rice husk ash and waste paper sludge ash was used as partial replacement of cement. The paper sludge is a result of paper making in the paper factory and rice husk is obtained from the preparation of rice from paddy. By including these parts into the bond it builds the quality, flexural and compressive quality of cement.

Utilization of Rice Husk Ash and Waste Paper Sludge Ash as Partial Replacement of Cement in Concrete - written by Rasik Fayaz, Er. Parvinderjeet Kaur, Er. Kiran Talwar published on 2018/07/30 download full article with reference data and citations
The paper presents the research results on the mobility of heavy metals in sewage sludge and ash. The geo-accumulation index, the potential ecological risk index, and the risk assessment code were used for the evaluation of the potential soil contamination with heavy metals.
The feasibility of using a low-cost super hydrophobic powder as water-resisting admixture or water-repellent surface coating for concrete has been investigated. The powder was produced from paper sludge ash (PSA), a by-product from the manufacture of recycled paper. The effect of hydrophobic PSA on workability, strength and transport properties ...
In this study waste paper sludge ash was partially replaced as 5%, 10%, 15% and 20% in place of cement in concrete for M-25 mix and tested for its compressive strength, tensile strength, water ...
Paper sludge ash is therefore potentially suitable as an ingredient in: - the cement kiln feed, contributing calcium, silica and alumina. - the manufacture of blended cements. This research will summarize the behavior of concrete with the waste paper sludge ash by replacement
Paper sludge ash is a material that is considered as an alternative binder to make concrete as like as GGBS, Rice Husk, Glass Powder, Fly ash, Phospogypsum etc. Paper mill sludge is a major pecuniary and environmental problem for the paper and board Portland cement ingredients.
Solid waste management, paper sludge ash (PSA), waste glass aggregate (WGA), concrete, alkali-silica reaction (ASR) Abstract: This short communication focuses on the potential use of paper sludge ash (PSA), a waste product of the paper making industry as an innovative binder partially replacing cement in concrete with glass aggregate. After
and is yet to be used on a large scale. Alternative uses for sludge ash, such as bricks and cement, are an excellent option if a user can be found near the mill and if long term contracts can be acquired. New products developed from pulp and paper mill sludge, however, need to have a market to make them economi-cally feasible.
Hence, a comparative analysis of the experimental results novel properties of fresh and hardened concrete with recycled concrete aggregates (RCA) with different substitution of waste paper sludge ash (WPSA) as a partial substitute for cement is presented in the paper. Recycled aggregates is made by crushing the waste concrete cube laboratory tests.
In this study waste pape r sludge ash (hypo sludge) was partially replaced as 5%, 10%, 15% and 20% in place of cement in concrete for M-15 m ix (i.e. concrete design mix of 1:2:4 cement, sand and aggregate as per IS 456: 2000) and tested for its compressive streng th,
The effect of fly ash on biodegradability and methane production from secondary paper and pulp sludge, including its modeling, was evaluated. Three tests with fly ash concentrations of 0, 10 and ...
