A NEW CONCRETE INCORPORATING WASTEPAPER SLUDGE ASH (WSA) This paper reports the results of a preliminary study into the properties of concrete manufactured with various binder blends incorporating Portland cement (PC), Wastepaper Sludge Ash (WSA) and Ground Granulated Blastfurnace Slag (GGBS).
5% replacement of Paper Sludge Ash gave the maximum Flexural Strength compared to other mix. 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.
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 The strength results are compared to those of normal Portland cement (PC) paste and relative strengths are reported.
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.
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
This paper investigates workability and strength of concrete made with different proportions of waste paper sludge ash (WSA) and ground granulated blastfurnace slag (GGBS) as binder, at two w/b rations: 0,5 and 0,4. Specimens were tested unconfined compressive strength after 1, .
and focused to improve the compressive strength of the black cotton soil. Waste paper sludge ash (WPSA) is waste product from the Paper mill industries. The WPSA can produce a cementitious material because WPSA contains a large amount of CaO while it is pozzolanic material. WPSA is incinerated from waste paper sludge.
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 91day compressive strength of mortar samples incorporating wt% and 10 wt% wastepaper sludge respectively retained 92% and 52% of the reference mortar strength.
The powder was produced from paper sludge ash (PSA), a byproduct 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.
One of the replacement materials is waste paper sludge ash (WPSA), a local industrial byproduct 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.
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
Waste paper sludge ash (WPSA) is a byproduct and problematic waste of paper industries. The investigation was driven by the increasing demand for reuse options in paperrecycling industry. This paper present on the morphology and physical analysis studies on polymerization of WPSA mortar. Two (2) types of polymeric mortar mixes containing WPSA with alkaline activators and .
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 ...
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 Xray Fluorescence (XRF) to .
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. The rice husk ash RHA and waste paper sludge ash (WPSA), were added to the

This paper investigates workability and strength of concrete made with different proportions of waste paper sludge ash (WSA) and ground granulated blastfurnace 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.
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,, 5, and 10 percent by weight of cement) of both silica fume and paper waste ash. In all mixtures of concrete, the .
