Show moreThis thesis addresses municipal ash-modified and fly ash-modified concrete utilization for the transportation infrastructure. The mix design included unmodified (control) concrete (Mix A), fly ash-modified concrete (Mix B), and municipal ash-modified concrete (Mix C). The laboratory investigation was carried out through compressive, tensile, testing of the cylinders and flexural testing of concrete slabs on grade comprised of varying proportions of coal fly ash and MSW bottom ash. The load-strain relationships for experimental pavements was obtained through slab testing, modeled as a two-way infinite slab on an elastic foundation. A finite element model using STAAD-III was used to predict the stresses and deflection of the slab. For comparison, a simplified analysis was also performed to obtain stresses and deflections variations of the slabs, following ACI Committee 436. Based on the results presented in this report, conclusions were drawn to evaluate the ideal mix design for municipal ash-modified and fly ash-modified concrete.

Show moreThe reuse of crushed aggregates for producing structural concrete is a major concern especially when it comes to its strength and durability. This study evaluated recycled aggregate concrete (RAC) for its strength and durability under simulated environmental degradation in the form of wetting-drying (W-D) cycles. The study consisted of two phases, each involving the determination of the compressive strength and modulus of elasticity using the conventional method and also a nondestructive ultrasonic pulse velocity method (Pundit Lab). Phase 1 involved 7-day curing followed by 30 W-D cycles, while Phase 2 included 28-day cured samples subjected to 15 W-D cycles. It was found that RAC specimens subjected to W-D cycles had minimal degradation in strength, making the use of RAC in construction very promising. Results from Pundit Lab compared reasonably well with conventional test results, showing promise as a nondestructive tool for the evaluation of RAC properties.

Show moreIntegrated Solid Waste Management systems consist, in order of their occurrence, of source reduction, recycling, composting, combustion, and landfilling. Present theory and practice emphasize recycling as the stage with the greatest potential for dealing with the problem of rapidly growing solid wastes. The central proposition of this dissertation is that the rate of recycling is largely dependent on local political, demographic, economic, and technological conditions. To test this, the recycling rates of 221 counties of Florida, Minnesota, and Pennsylvania were examined. Primary data were gathered using a questionnaire-based survey sent to all 221 county recycling coordinators. An overall response rate of 62.9 percent was achieved. Twenty-four variables were tested for their relationship to recycling rates. Of these, four demographic variables, two economic variables, and four technological variables were identified as being significantly (p<0.05) related to the recycling rates in one or more states. No political variables were found to be significantly related to recycling rates in any state. A recycling model was developed for each state using multiple regression techniques. The Florida and Minnesota models suggest that recycling is highly influenced by local demographic factors, while the Pennsylvania model suggests that in that state the dominant influence is exerted by technological factors. The study developed the importance of the concept of per capita daily generation of municipal solid wastes. This concept, labeled "CMSW" was not found in the literature, but emerged from the study itself. CMSW, combined with the concept of non-recycled CMSW, were highlighted as practical and theoretically relevant variables for use in future research in the area of solid waste management.

Title: An Experimental Evaluation of High Volume Fly Ash Structural Concrete made from Recycled Aggregate.
Creator: Theodorou, Anthony Lloyd, Sobhan, Khaled, Florida Atlantic University, College of Engineering and Computer Science, Department of Civil, Environmental and Geomatics Engineering
Abstract/Description: Three vital factors, namely environmental protection, savings in costs, and strength/durability benefits, make it advantageous to incorporate fly ash of controlled quality and composition in all concrete made from construction demolition (C&D) recycled aggregate. The specific objective of this research was to compare the performance characteristics of High-Volume-Fly-Ash (HVFA) structural concrete containing C&D aggregate with that of normal recycled aggregate concrete containing no fly ash....
Show moreThree vital factors, namely environmental protection, savings in costs, and strength/durability benefits, make it advantageous to incorporate fly ash of controlled quality and composition in all concrete made from construction demolition (C&D) recycled aggregate. The specific objective of this research was to compare the performance characteristics of High-Volume-Fly-Ash (HVFA) structural concrete containing C&D aggregate with that of normal recycled aggregate concrete containing no fly ash. A coordinated experimental program was undertaken which comprised of ( 1) Compressive and Split Tensile strength tests; (2) ASTM durability tests by measuring resistance to chloride-ion penetration; and (3) Flexural strength tests on reinforced concrete beam specimens. Three mix designs were used, all of which had the same water/cement ratio of 0.45 and the same amount of recycled aggregate/yd^3. Mix 1 contained cement and no fly ash, Mix 2 contained 16% replacement of cement by weight, and Mix 3 contained 40% replacement of cement, called a HVF A mix. Results indicate that fly ash increases compressive strength, improves both moment carrying capacity and tension resistance, and increases resistance to chloride-ion attack.

Show moreLong term durability is a major concern for wide-scale use of recycled aggregate materials in civil engineering construction. The purpose of this study is to provide an insight into the damaging effects of combined wet-dry cycles and repeated mechanical loading in a recycled aggregate concrete (RAC) base course material made from recycled crushed concrete aggregate and cement. A coordinated experimental program followed by a mechanistic pavement modeling and life cycle analysis was conducted as part of this research study. This laboratory investigation was divided into three phases each consisting of both wet-dry exposed specimens (WD), and control or non wet-dry exposed specimens (NWD). Phase I experiments involved monotonic loading tests under compression and flexure to evaluate the strength properties. Phase II involved testing a total of 108 cylindrical specimens in cyclic compressive loading at three different stress ratios. After each regime of cyclic loading, residual compressive strengths were determined. In addition, the load-deformation hysteresis loops and the accumulated plastic deformation were continuously monitored through all loading cycles. Phase III included a flexural fatigue test program on 39 beam specimens, and fracture testing program on 6 notched beam specimens, each one having 19-mm initial notch. Traditional SR-N curves, relating the Stress Ratio (SR) with the number of cycles to failure (N or Nf), were developed. Fatigue crack growth rate and changes in Stress Intensity Factors were obtained to determine Paris Law constants and fracture toughness. A mechanistic analysis of a typical highway pavement incorporating RAC base was performed with KENPAVE program, followed by a Life Cycle Analysis (LCA) using the GaBi software. It was found that the specimens subjected to wet-dry cycles suffered significantly higher damage expressed in terms of accumulated plastic deformation, and loss of residual compressive strength, modulus, fatigue endurance limit, and design life, compared to specimens not exposed to wet-dry cycles. Although such degradation in material properties are important considerations in pavement design, a concurrent Life Cycle Analysis demonstrated that recycled aggregate concrete base course still holds promise as an alternative construction material from environmental stand point.

Show moreThis thesis examines the scope of the plastic waste management and housing problems in Haiti. It makes a case for plastic waste to be recycled into sustainable housing as a solution to both issues. For better understanding, it first analyses the scope of the plastic waste pollution and housing problems in developing countries. It then ascertains innovative ways waste managers, and planners have solved it in these nations. Thirdly, based on case studies in Colombia and India, this thesis ascertains how using plastic waste in construction, is a potential solution for better waste management and better housing in Haiti. In the end, this thesis recommends the construction of a plastic waste recycling plant in Port-au-Prince to help solve both their waste and housing problem. Since Port-au-Prince lacks a central sewage system, this thesis also recommends investment in water infrastructures to eliminate the need for plastic bottles in the long run.

Show moreGeopolymer concrete (GC) is a sustainable construction material and a great alternative to regular concrete. GC is a zero-cement material made from a combination of aluminate, silicate and an activator to produce a binder-like substance. This investigation focused on the effects of wet and dry cycles on the strength and durability of fly ash-based recycled aggregate geopolymer concrete (RAGC). The wet-dry cycles were performed approximately according to ASTM D559 standards. RAGC specimens with nearly 70% recycled materials (recycled aggregate and fly ash) achieved a compressive strength of approximately 3600 psi, after 7 days of heat curing at 60ºC. Although the recycled aggregate is prone to high water absorption, the compressive strength decreased by only 4% after exposure to 21 wet-dry cycles, compared to control specimens that were not exposed to the same conditions. Accordingly, the RAGC material developed in this study can be considered as a promising environmentally friendly alternative to cement-based regular concrete.

Show moreOne compelling reason for converting to reusable containers is the conservation of natural resources. Other than the attractiveness of a potential cost savings, it could provide the firm with a good public relations image worth even more. Many firms are working toward being ISO (international Standards Organization) 14001 certified. ISO 14001 includes in its guidelines the need to reduce pollution. With this in mind, there is a need for better tools to predict cost when converting from disposable to reusable containers. This study provides a tool to estimate conversion cost based on a mathematical model that captures the important elements of cost. It is also based on inventory control methods, design of experiments and a simulation model with animation that captures these cost elements as well. Some guidelines that will help sell a reusable container project to upper management, together with a discussion on implementation logistics, is presented as well.

Title: Potential applications for recycled glass in beach management: Emergency stabilization of erosional "hot spots" in Broward County, Florida.
Creator: Kerwin, Loisa, Florida Atlantic University, Finkl, Charles W., Charles E. Schmidt College of Science, Department of Geosciences
Abstract/Description: In Florida beach renourishment is the preferred management technique used to maintain the integrity of local beaches, which generate over 7.9 billion a year in revenues from tourism. Beaches are dynamic and often exhibit accelerated rates of erosion and shoreline retreat. Sites that erode more than twice the regional background rate are classified as "erosional hot spots" (EHS). Emergency remediation of EHS is necessary to avoid loss of beach sand from renourished beaches. Because suitable...
Show moreIn Florida beach renourishment is the preferred management technique used to maintain the integrity of local beaches, which generate over 7.9 billion a year in revenues from tourism. Beaches are dynamic and often exhibit accelerated rates of erosion and shoreline retreat. Sites that erode more than twice the regional background rate are classified as "erosional hot spots" (EHS). Emergency remediation of EHS is necessary to avoid loss of beach sand from renourished beaches. Because suitable offshore borrow materials are limited in Broward County, coastal managers are seeking alternative sources of compatible beach fill materials. The manufacturing of glass sand from processed recycled glass is a new, innovative technology. This report evaluates the potential application of glass sand for EHS remediation along renourished shores. Benefits of processed glass sand are: (1) preferred grain size by crushing of recycled glass, (2) an environmentally inert material, and (3) physical properties similar to the composition and color of native sand. The recycling industry in Florida generates almost 100,000 m^3 of glass a year, 30% of which is unsuitable for recycling. Alternative uses for waste glass cullet are being sought to reduce the high cost of disposal in landfills.
