Available in PDF, EPUB and Kindle. Book excerpt: Coal powered power plants account for more than 40 percent of the electricity production of the United States. The combustion of coal results in a large number of solid waste materials, or coal combustion byproducts (CCBs). These waste materials are stored in landfill or ponds. The construction industry is heavily reliant on concrete which is used to make the building blocks for any type of structures, bricks. Concrete is a composite material made of a binder and coarse and fine aggregate. The most widely used binder in concrete production is Ordinary Portland Cement (OPC). Since cement manufacture is costly and environmentally damaging, research has increased in recent years to find a more readily available binder. This study aims at investigating the properties of Illinois fly ash as a binder in the production of geopolymer concrete. Geopolymer concrete is an innovative material made by using Alumina and Silica rich materials of geological origins as a binder as well as an alkali activated solution. Sodium Silicate and Sodium Hydroxide were used to make the activator solution of two different ratios. Geopolymer Concrete with a ratio of 1:1 of Sodium Silicate to Sodium Hydroxide reached a compressive strength above 6000 psi while samples made with a ratio of 1:2 reached a compressive strength above 4000 psi. This environmentally-friendly, green concrete was also found to have a cost comparable to conventional concrete.

This book was released on 2021-09-05 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Portland cement based concrete is the most versatile, durable and reliable building material. Unfortunately, the production of Portland cement is environmentally unfriendly. An interesting alternative is provided by alkali-activated geopolymer materials (AAGM). This book focuses on fly ash-based alkali-activated geopolymer concrete, its production and characteristic properties. The re-use of waste materials and industrial by-products, such as fly ash, is not only economically of interest but also helps to reduce carbon dioxide emissions. The carbon footprint of these materials is much lower than that of concrete using ordinary Portland cement. They thus offer new sustainable solutions to the construction industry. Keywords: Geopolymers, Geopolymer Concrete, Alkali-activated Geopolymer Materials (AAGM), Portland Cement, Fly Ash-based Geopolymer Concrete, Reduction of Carbon Dioxide Emissions, Concrete Applications, Self-Compacting Concrete, High-strength Concrete, High-performance Concrete.

Download or read book Feasibility Study of Using Ground Bottom Ash in Geopolymer Concrete written by Navin Paija and published by . This book was released on 2017 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: United States alone has about three quarters of the accessible worldwide reserve of coal. There are about 511 coal-powered electric plants and generates about 33% of the nation's electricity. The combustion of coal results in a large number of solid waste materials known as coal combustion byproducts (CCBs) that are stored in landfill or ponds. These are easily accessible and with proper research it can be put into beneficial use. Today concrete is the second most consumed substance after water. Concrete, a composite material made of a binder in combination with coarse and fine aggregate, is used in foundations and structures of buildings, bridges, roads, dams. Cement is the most widely used binder for concrete, however, research has shown that a single cement industry produces approximately 5% of global CO2 emissions, and one ton of Portland cement emits approximately one ton of CO2. This emission of CO2 is one of the main reasons for global warming and has detrimental impacts on environment. The possibility of using fly ash and bottom ash as an alternative to cement as a binder to produce sustainable concrete is investigated in this study. The process of geopolymerization includes the reaction of ash and an alkali activated solution made of diluted sodium silicate and sodium hydroxide. The initial objective of this study was to produce fly ash geopolymer concrete which has a strength comparable to that of cement concrete. However, later the possibility of bottom ash as a binder material for geopolymer production was also studied. During this study, the strength of conventional mortar with 10%, 20%, and 30% cement replacement with fly ash and bottom ash was experimented and compared with strength of cement mortar. The test results showed that with increase in the fly ash and bottom ash replacement the strength of the mortars decreased, moreover, the mortars that was replaced by bottom ash produced better results than that of the fly ash replacement. Also, the effect of increase in the ratio of sodium silicate to sodium hydroxide ratio on the strength of geopolymer mortar is studied. Sodium silicate to sodium hydroxide ratio of 1.5, 2.5, and 3 is used in this ratio, and the test results showed that with the increase in this ratio the compressive strength of geopolymer mortar also increased. Similarly, different combinations of fly ash and bottom ash is used to produce geopolymer mortars. The results showed that geopolymer mortar with higher bottom ash content produced better results. The effect of ground fly ash and bottom ash on the compressive strength of geopolymer mortar is also studied. The test result showed that with increase in fineness of fly ash and bottom ash, there was slight improvement in the strength.

This book was released on 2023-05-31 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: DEVELOPMENT OF GEOPOLYMER FROM POND ASH-THERMAL POWERPLANT WASTE Explains how geopolymer technologies using industrial waste obtained from thermal power plants become cementitious materials in construction sectors for civil engineers. Utilization of waste materials has become a global challenge since they endanger our environment. In this book, the authors demonstrate how to utilize fly ash/pond ash (waste materials from thermal power plants) to produce a novel material called ‘Geopolymer’ (GP). Red mud, slags, etc., are mixed with fly ash to produce GP with enhanced strength. As shown in a few European countries, GP can replace cement, and some permanent structures constructed with GP are now appearing in a few advanced countries. GP, and geopolymer concrete, is considered suitable for the construction of roads, buildings, etc., and will eventually, fully or partially, replace cement. The book highlights the mechanism of the formation of GP from pond ash. Properties of structures made with GP concrete are found to be comparable to those made with cement concrete. Systematic investigations are presented to understand the chemistry of GP formation with pond ash materials. Performances of these materials above ambient temperature, as well as with different environmental conditions, are also evaluated.

Book excerpt: Handbook of Powder Technology, Volume 1: Particle Size Enlargement is the first of a series which will together form a Handbook of Powder Technology, primarily intended for engineers and scientists working in industry. The scope of the Handbook can be defined as being concerned with that part of chemical engineering which deals with processes involving the handling and treatment of material in solid particulate form. This book deals with methods used to create larger entities from fine particles so that the bulk properties of particulates can be improved. These so-called ""size enlargement"" methods evidently concern a broad spectrum of technical disciplines and industries ranging from the relatively small scale requirements of pharmaceutical manufacturers through the tonnage requirements of the fertilizer and minerals processing industries. A primary objective in preparing this book was to present a generalized account of the many size enlargement techniques scattered throughout these diverse industries, with emphasis on similarities and unifying characteristics whenever possible. The book devotes one chapter to each of the principal methods used to bring particles together into agglomerates: agitation methods— tumbling agglomeration, agitation methods—mixer agglomeration, pressure methods, thermal methods, spray and dispersion methods, and agglomeration from liquids.

Download or read book Development of Green Concrete Using Geopolymer written by Diana Chami and published by . This book was released on 2019 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Portland cement is the main component of traditional concrete used for construction; hence it is widely used. The production of Portland cement produces a high amount of CO2 what makes it harmful for the environment. Therefore, geopolymer concrete has been of interest since it serves the same utilities as Portland cement concrete by using a different type of raw material. This material is coming from waste therefore do not cause environmental damage. This binder is created using materials rich in alumina and silica with addition of an activating solution known as the alkali solution. Fly ash coming from the burning of coal is used in this study along with an activating solution composed of sodium hydroxide and sodium silicate to produce an alternative binder for concrete. Fly-ash will be partially substituted by Glass Powder which is also a waste material to see its effect on geopolymer concrete. Moreover, the durability of geopolymer concrete will be checked and compared to that of ordinary Portland cement concrete in terms of acid attack and fire resistance. Therefore, mixtures with different percentages of glass powder (0%, 5%, 10% and 20%) were carried out and different molarities of NaOH (10M and 14M) to generate a geopolymer concrete that has workability, strength and durability properties. Compressive strength, acid attack, and fire resistance are the tests that are respectively done for the previously mentioned properties. Results showed that 5% glass powder replacement of fly-ash in geopolymer concrete with 14M as NaOH concentration gives a similar fc of 48.32 MPa compared to the reference GPC without glass that gives 47.73 MPa. Also, up to 10% substitution of fly-ash with glass powder do not have a major effect on the strength (45.8 MPa). In addition, geopolymer concrete gives better durability properties than ordinary Portland cement concrete.
