In this research, the results of experiments achieved on some mixtures of concrete comprising silica fume and paper waste ash as a substitute to Portland cement have been presented. The Portland cement was substituted with various ratios (namely 0,2.5, 5, 7.5 and 10 percent by weight of cement) of both silica fume and paper waste ash. In all mixtures of concrete, the .
46 Background Waste paper mill sludge is the byproduct of the paper produc- tion process. The major byproducts from the pulp and paper waste stream are ( and Talberth 2008): â ¢ Waste water treatment plant (WWTP) residuals â ¢ Boiler and furnace ash â ¢ Causticizing residuals.
Waste paper sludge ash (WPSA) is a byproduct that has potential to replace Ordinary Portland Cement (OPC) as a building material. The purpose of this study is to investigate the effect of NaOH concentration on the strength of Waste Paper Sludge Ash (WPSA)-based geopolymer mortar. Initially, the WPSA samples were been analyzed using X-ray Fluorescence (XRF) to .

Keywords: Paper Sludge Ash (PSA), Foundry Sand (FS), Compressive Strength, Tensile Strength, Flextural Strength. 1. INTRODUCTION In this rapid moving era of construction industry plays a very important role in of infrastructure development of any Country.
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, including sorptivity, water absorption, diffusivity, permeability and electrical conductivity is reported.
May 12, 2015· Abstract. This paper presents findings on the soft soil stabilization using waste paper sludge ash (WPSA). A laboratories testing was conducted to determine the compressive strength, total shear strength and effective shear strength on soft soil subgrade stabilized using WPSA mixtures.
This paper investigates workability and strength of concrete made with different proportions of waste paper sludge ash (WSA) and ground granulated blast-furnace slag (GGBS) as binder, at two w/b rations: 0,5 and 0,4. Specimens were tested unconfined compressive strength after 1, .
This paper investigates workability and strength of concrete made with different proportions of waste paper sludge ash (WSA) and ground granulated blast-furnace slag (GGBS) as binder, at two w/b rations: 0,5 and 0,4. Specimens were tested unconfined compressive strength after 1, .
(2003). WASTE PAPER SLUDGE ASH AND GROUND GRANULATED BLAST FURNACE SLAG AS BINDER IN CONCRETE. Journal of Civil Engineering and Management: Vol. 9, No. 3, pp. 198-202.
Feb 01, 2006· Wastepaper sludge ash (WSA) requires relatively higher proportions of water than Portland cement (PC) when used as a single binder. This high water demand may be reduced by the addition of secondary binders such as ground granulated blastfurnace slag (GGBS), which improves the hydration properties of the mixes.
One of the replacement materials is waste paper sludge ash (WPSA), a local industrial by-product generated abundantly by newsprint mills which possesses considerable cementitious properties. Parallel to this, the high amount of construction waste, particularly concrete waste has become a difficult environmental issue to cope with in todays world.
Oct 19, 2016· 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.
May 31, 2020· Compressive strength and hydration characteristics of wastepaper sludge ash–ground granulated blastfurnace slag (WSA–GGBS) blended pastes were investigated at a water to binder (w/b) ratio of 0.5.
Cement manufacturing industry is one of the foremost carbon dioxide emitting sources besides deforestation and burning of fossil fuels and concrete industry is one of the largest consumers of natural materials. The global cement industry

The Portland cement was substituted with various ratios (namely 0,2.5, 5, 7.5 and 10 percent by weight of cement) of both silica fume and paper waste ash. In all mixtures of concrete, the ratio of cement to water ...
Aug 01, 2003· Compressive strength and hydration characteristics of wastepaper sludge ash–ground granulated blastfurnace slag (WSA–GGBS) blended pastes were investigated at a water to binder (w/b) ratio of 0.5. The strength results are compared to those of normal Portland cement (PC) paste and relative strengths are reported.
Dec 15, 2012· Addition of wastepaper sludge to geopolymer mortar reduces flow properties, primarily due to dry sludge absorbing water from the binder mix. The average 91-day compressive strength of mortar samples incorporating 2.5 wt% and 10 wt% wastepaper sludge respectively retained 92% and 52% of the reference mortar strength.
compressive strength of concrete blocks manufactured using wastepaper sludge ash Authors: G. Veerappan, J. M. Kinuthia, M. O'Farrell, B. B. Sabir, S. Wild Source: Recycling and Reuse of Waste Materials, 1 Jan 2003 (563–575)
present investigation, a feasibility study is made to use Rice Husk Ash and Waste Paper Sludge Ash as an admixture to Ordinary Portland Cement in Concrete, and an attempt has been made to investigate the strength parameters of concrete (Compressive and Splitting Strength). For control concrete, IS method of mix design is adopted and considering ...

This paper investigates workability and strength of concrete made with different proportions of waste paper sludge ash (WSA) and ground granulated blast-furnace slag (GGBS) as binder, at two w/b rations: 0,5 and 0,4. Specimens were tested unconfined compressive strength after 1, 7, 28 and 90 days of curing.
incinerated to waste paper sludge ash (PSA) in Combined Heat and Power (CHP) plants at the paper mill at approximately 800ºC and disposed of in landfills. The possibility of using this ash in concrete is investigated in this paper. Concrete is the most common material used in .
Abstract: 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 paper sludge is a result of paper making in the paper factory and rice husk is obtained from the preparation of rice from paddy.
