waste paper sludge ash use in geopolymer cocrete

Mechanical and durability properties of fly ash geopolymer ...for geopolymer was waste paper sludge ash instead of pop-ularly used fly ash and slag. Results show that the compres-sive strength is increased by about 10% from 7 days to 28 days and high molarity of sodium hydroxide shows higher compressive strength in geopolymer concrete. Shuang et al. (2012) evaluated the mechanical properties of ...UNIVERSITI TEKNOLOGI MARA STRENGTH AND SHRINKAGE OF ...concern. Waste paper sludge ash (WPSA) is a by-product and problematic waste of paper industries in Malaysia. WPSA is found having a potential to replace OPC as a concrete binder. Geopolymer concrete technology is seen as one of the best option to reduce the amount of CO2 emitted in OPC production in order to satisfy construction material needs.EXPERIMENTAL STUDY ON EFFECTS OF SLUDGE WASTE IN .EXPERIMENTAL STUDY ON EFFECTS OF SLUDGE WASTE IN CONCRETE Bharat Nagar*, Prof V. P. Bhargava ... Badr El-Din et al. presented some results from brick manufacturing by mixing water treatment sludge with rice husk ash.

The alkaline liquid that been used in geopolymerisation...Compressive strength of fly‐ash‐based .This paper presents the compressive strength of fly‐ash‐based geopolymer concretes at elevated temperatures of 200, 400, 600 and 800 °C. The source material used in the geopolymer concrete in this study is low‐calcium fly ash according to ASTM C618 class F classification and is activated by sodium silicate (Na 2 SiO 3 ) and sodium ...

Development of Paper Sludge Ash-Based .

28.07.2016· Flexural strengths of PS-ash-based geopolymers with liquor/filler ratios (L/F) of 1.0-1.5 ranged from 0.82 to 1.51 MPa at 4 weeks age, depending on PS-ashes and liquors used. The reaction process of the constituent minerals of the PS-ash is discussed. Furthermore, we attempted to solidify hazardous water contaminated with radioisotopes.Strength and shrinkage of incinerated waste .Waste paper sludge ash (WPSA) is a by-product and problematic waste of paper industries in Malaysia.

Geopolymer Concrete Fabricated by Waste .

As a relatively new material, geopolymer concrete offers the benefits as a construction material for sustainable development. It utilized waste materials such as recycled concrete sludge, fly ash and etc. It has a very low rate of green house gas emission when compared to ordinary Portland cement.Experimental Study of Geopolymer Concrete .This paper investigates complete recycling of waste concrete to produce new geopolymer concrete (GPC). Specifically, GPC was produced using waste concrete fines (WCF) and class-F fly ash (FA) together with mixed sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) solution as the geopolymer binder and waste concrete aggregates (both coarse and fine) as the aggregate.STRENGTH CHARACTERISTIC OF GEOPOLYMER .Waste Paper Sludge Ash (WPSA) and alkaline liquid as a binder are being used to replaced the Portland cement to produce geopolymer concrete. The alkaline liquid that been used in geopolymerisation is the combination of sodium hydroxide (NaOH) and sodium silicate (Na2SiO3).Effect of Glass Powder on Geopolymer ConcreteA geopolymer concrete is a mixture of geopolymer binder and aggregate. Several waste material and other industrial bypro- ducts such as fly ash, silica fume, rice husk ash etc can be used as source material for geopolymer binder. In this study fly was used as the main source material as geopolymer binder.Synthesis of water treatment sludge ash-based .01.11.2019· Four key materials were employed in the geopolymer synthesis: a WTP-based sludge and a slag-based Portland cement as precursors, an industrial sand as aggregate, and a liquid alkaline solution as activator. The sludge was collected from Ponta das Lajes water treatment plant located in the southern area of Manaus.Morphology and Physical Analysis of Waste Paper .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 paper-recycling 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 without alkaline ...Strength and shrinkage of incinerated waste .Waste paper sludge ash (WPSA) is a by-product and problematic waste of paper industries in Malaysia. WPSA is found having a potential to replace OPC as a concrete binder. Geopolymer concrete technology is seen as one of the best option to reduce the amount of CO² emitted in OPC production in order to satisfy construction material needs.Properties of Waste Paper Sludge Ash (WPSA) as .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.
