Available in PDF, EPUB and Kindle. Book excerpt: High Volume Fly Ash Concrete (HVFA) is a type of concrete that incorporates a large volume of fly ash as a partial replacement for Portland cement. Fly ash is a by-product of coal combustion that is collected from power plants, and it has pozzolanic properties that can enhance the durability, workability, and strength of concrete. In HVFA, the replacement of Portland cement with fly ash typically ranges from 50% to 70% by mass, resulting in a reduction in the amount of cement required and a decrease in the carbon footprint of the concrete. However, this high volume of fly ash can also affect the behavior of the concrete in structural design. One of the main challenges in designing with HVFA concrete is the potential for delayed strength development. Fly ash reacts slowly with water, and this can result in a longer period for the concrete to reach its desired strength. This delayed strength development must be taken into account in the design process to ensure that the concrete can support the intended loads. Additionally, the use of HVFA can also affect the workability and setting time of the concrete. The high amount of fly ash can make the mixtures more viscous and harder to place, and it can also result in longer setting times. This can impact the construction schedule and require adjustments to be made in the mix design and placement procedures. On the other hand, HVFA can also provide benefits in structural design. The lower heat of hydration and reduced shrinkage characteristics of HVFA can minimize the potential for cracking and improve the long-term durability of the concrete. Furthermore, the use of fly ash can contribute to the overall sustainability of the project by reducing the carbon footprint and diverting waste from landfills. Overall, the behavior of HVFA concrete in structural design requires careful consideration of its unique properties and potential challenges. With proper mix design and construction practices, HVFA can provide a durable and sustainable option for concrete structures.

This book was released on 2024-01-20 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: When infrastructure is built quickly, development occurs. Concrete is the go-to material for construction projects. Manufacturing cement is a significant contributor to atmospheric carbon dioxide. Using carbon-neutral materials like crimson mud or powdered snail shells can reduce cement's carbon dioxide emissions by half. As an adaptable alternative to traditional concrete, HVFA concrete has many uses. Long-lasting and useful in Plain Cement Concrete (PCC) projects, fly ash also enhances concrete's workability. The positive effects of fly ash on the environment, such as lower carbon dioxide emissions, are not new. Adding fly ash to concrete increases its strength and segregation, which reduces its price and makes it simpler to pump.

This book was released on 2008-11-01 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research was to examine the applicability of ternary binder systems containing ordinary portland cement (OPC), class C fly ash (FA) and silica fume (SF) for bridge deck concrete. This was accomplished in two parts, the laboratory part and a field application part. During the laboratory studies, four ternary mixtures, each containing either 20% or 30% FA and either 5% or 7% SF were subjected to four different curing regimes (air drying, 7 days curing compound application and 3 or 7 days wet burlap curing). In general, all four ternary mixtures exhibited very good water and chloride solution transport-controlling properties (resistance to chloride-ion penetration, chloride diffusivity and rate of water absorption). However, it was concluded that in order to ensure adequate strength, good freezing and thawing resistance, satisfactory resistance to salt scaling, and adequate shrinkage cracking resistance the FA content should not exceed 20%, SF content should not exceed 5% (by total mass of binder) and paste content should be kept below 24% by volume of concrete. Further, wet burlap curing for a minimum of 3 days was required to achieve satisfactory performance and to obtain a reliable assessment of in-situ compressive strength (up to 28 days) using maturity method. The second part of this research examined the performance of ternary concrete containing 20% FA and 5% SF in the pilot HPC bridge deck constructed in northern Indiana. Using maturity method developed for the purpose of this study, it was determined that the unexpectedly high RCP values of concrete placed late in the construction season were mostly attributed to low ambient temperature. Additional applications of the developed maturity method were also demonstrated. These include assessment of risk of scaling and reduction in time to corrosion initiation as a function of construction date, as well as estimation of long-term RCP values of concrete subjected to accelerated curing.

Available in PDF, EPUB and Kindle. Book excerpt: A best practices guide is developed from a synthesis of recent research on high-volume fly ash (HVFA) concrete mixtures. These best practices can be applied by the concrete construction industry to achieve desired properties and to ensure the (high) performance of HVFA concrete mixtures in practice. As such, the report considers all aspects of HVFA concrete production, from the characterization of the starting materials, through mixture proportioning and curing options to achieve desired properties, to the in-place early-age and long-term performance of the concrete in its fresh and hardened states. Both mechanical and transport properties are considered in detail. Perspective is established based on a brief review of current practices being employed nationally. Each topical section is concluded with a practice-based set of recommendations for the design and construction community. The report is intended to serve as a valuable resource to these communities, providing both a research summary and a guide to practical steps that can be taken to achieve the optimum performance of these sustainable concrete mixtures.

This book was released on 2012 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Concrete is the most widely used man-made material on the planet. Unfortunately, producing Portland cement generates carbon dioxide (a greenhouse gas) at roughly a pound for pound ratio. High-volume fly ash (HVFA) concrete- concrete with at least 50% of the cement replaced with fly ash - offers a potential "green" solution. However, because it is still relatively new and has some disadvantages, there are still many questions that need to be answered. Most research to date has consisted only of the evaluation of the strength and durability of HVFA concrete mixtures, while only a limited number of studies have implemented full-scale testing of specimens constructed with HVFA concrete to determine its potential use in the industry. For this research, a laboratory testing program was developed to investigate the shear performance of reinforced concrete (RC) beams constructed with HVFA concrete. The experimental program consisted of 36 tests performed on full-scale RC beams. The principal parameters investigated were: (1) concrete type (HVFA or conventional concrete), (2) amount of shear reinforcement, and (3) amount of longitudinal (flexural) reinforcement. The full-scale beams in this study were analyzed using several different approaches, including the standard truss model, modified compression field theory, and fracture mechanics formulations. The full-scale test results were compared to the theoretical results using design approaches contained in several codes common to North America and Europe. The results indicate that existing design code provisions for conventional concrete are equally applicable to the design of HVFA concrete"--Abstract, leaf iii.

Available in PDF, EPUB and Kindle. Book excerpt: Recent studies, including those by the investigators, have shown that higher cement replacement percentages -- even up to 75 percent -- can result in excellent concrete in terms of both strength and durability. Referred to as high-volume fly ash (HVFA) concrete, this material offers a viable alternative to traditional portland cement concrete and is significantly more sustainable. However, HVFA concrete is not without its problems. At all replacement rates, fly ash generally slows down the setting time and hardening rates of concrete at early ages, especially under cold weather conditions, and when less reactive fly ashes are used. Furthermore, with industrial by-products, some variability in physical and chemical characteristics will normally occur, not only between power plants but also within the same plant. Consequently, to achieve the benefits of HVFA concrete, guidelines are needed for its proper application in bridges, roadways, culverts, retaining walls, and other transportation-related infrastructure components. The objective of this research was to design, test, and evaluate HVFA concrete mixtures. The study focused on the hardened properties of HVFA concrete containing aggregates and fly ash indigenous to the state of Missouri and developed guidelines on its use in infrastructure elements for MoDOT.
