Evolving Hangwuran City Development Model Through Partial Least Square Approach In North-Central Nigeria, Samuel Medayese, Hangwelani H. Magidimisha-Chipungu, Lovemore Chipungu
CSID Journal of Infrastructure Development
The need for a paradigmatic shift in city development ideology has become increasingly evident over the years. In response to this need, the Hangwurian City Development Model was developed to establish a connection between the concepts of environmental awareness, urban governance, and management. This model also integrates sustainable urban development, urban liveability, and inclusive physical development. The research sets a critical objective of analyzing the significant levels of various indicator variables. The exploratory research utilized partial least squares (PLS) via SmartPLS to evaluate the variables, collecting quantitative data through the open data toolkit from three selected cities: Lokoja, Minna, and …

Synthesis And Characterization Of Cellulose Microfibril-Reinforced Polyvinyl Alcohol Biodegradable Composites, Fatemeh Mahdiyeh-Boroujeni, Gabriella Fioravanti, Ronald Kander
School of Design and Engineering Papers
The pursuit of an environmentally sustainable manufacturing process requires the substitution of less damaging and recyclable solutions for harmful reagents. This study aims to assess the effectiveness of using cellulose microfibrils synthesized via different hydrolysis reactions as reinforcing agents in polyvinyl alcohol (PVA) at varying concentrations. The investigation explores the morphology, thermal properties, and chemical behavior of the cellulose particles. The cellulose microfibrils (CMFs) produced using citric acid exhibited the highest yield and aspect ratio. Notably, particles from organic acids demonstrated greater thermal stability, with oxalic acid-derived particles displaying the maximum thermal degradation temperature. Subsequently, cast films of PVA reinforced …

Out-Of-Plane Flexural Behavior Of Insulatedwall Panels Constructed With Large Insulation Thicknesses, Jacob Luebke, Fray F. Pozo-Lora, Salam Al-Rubaye, Marc Maguire
Durham School of Architectural Engineering and Construction: Faculty Publications
Insulated concrete sandwich wall panels (ICSWPs) are gaining popularity as energy regulations become stricter worldwide. ICSWPs are now being constructed with thinner wythes and thicker insulation to keep up with the changing market, which is reducing material costs and increasing thermal and structural efficiency. However, there is a need for adequate experimental testing to validate the current design methods for these new panels. This research aims to provide that validation by comparing the predictions of four different methods with experimental data obtained from six large-scale panels. The study found that while current design methods adequately predict the behavior of thin …

Performance Assessment Of Bioasphalt Mixtures Containing Guayule Resin As An Innovative Biobased Asphalt Alternative, Ahmed Hemida, Magdy Abdelrahman
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Guayule resin was investigated through mixture to assess its role in the field performance. For performance comparisons, conventional asphalt, neat guayule, asphalt-rubber-guayule, and guayule-rubber binders were implied. Field-simulated lab mixtures were made to investigate the major distresses. Modified Lottman, rut, semicircular bending, and disk-shaped compact tension tests were used to assess stripping, rutting, fatigue, and thermal cracking resistances. Stripping and rutting susceptibilities were also assessed by Hamburg wheel-tracking test. The outcomes disclosed that when the modified Lottman test was used, guayule containing a 7% air content was more susceptible to stripping than that containing a 3.5% air content, resulting in …

Precious Plastics - Plastic Brick Machine Fabrication, Timothy Ukaobasi Kanu, Evi Paraskevi Troulis
Architectural Engineering
The goal of this research is to determine the structural parameters of the recycled plastic polypropylene when molded into bricks resembling CMU blocks. To accomplish this, three mechanisms had to be assembled: the shredder, the injector, and the 1x1 mold. A tensile and compression test were to be performed on the plastic brick, and the values would be used to compare the tensile and compressive strength of PP plastic bricks, as well as their modulus of elasticity and stress vs. Strain performance. These values would be analyzed to determine whether it would be feasible to build an entire plastic wall. …

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Incorporating phase change material (PCM) into paving materials can regulate the pavement temperature, improve the pavement durability, and mitigate the heat-island effects. In this research, porous fillers were used as the PCM carrier, and the thermal and rheological behaviors of the asphalt mastic with the PCM were evaluated. Two different carrier materials (diatomite and expanded perlite) and four types of PCMs were used in the study. The candidate filler, PCM, and proper blending ratios were determined based on the results of scanning electron microscope image analysis, the filter paper test, and the temperature sweep test. The thermal and rheological behaviors …

Proposal For Adobe Earthbag Disaster-Relief Structure, John Camacho
Construction Management
The science behind creating an adobe house has been around for thousands of years; the primitive mixture contains only dirt, water, and straw. Left to cure in bricks or as a single cast-in-place system, the structure will provide long-lasting protection from the elements. Science has taken this a step further with the introduction of cementitious admixtures and reinforcement. The result is an adobe structure with exemplary thermo-retentive properties and load-bearing capabilities. This project provides an analysis on the “SuperAdobe” earthbag system that has been put into practice by independent contractors and housing-relief initiatives. The goal of the project was to …

Strategic Energy Master Planning For Carbon Neutrality, Marie Patterson
CSU Journal of Sustainability and Climate Change
Universities across the United States are generating goals to be more sustainable and carbon neutral. The energy used in existing buildings on campuses amount to a large volume of greenhouse emissions and must be reduced to help achieve neutrality goals. Strategic Energy Master Plans are instrumental to support these goals through the development of recommendations to reduce energy. Calculating the energy use intensity for existing buildings, a main component of a Strategic Energy Master Plan, can help the campus understand where energy is being used the most. With this information the highest energy consuming buildings can be the focus of …

BAU Journal - Creative Sustainable Development
The strategic location of Bahrain and its wealthy marine and coastal environment were the main drivers for the country’s flourishment before the discovery of oil. For a long time, Bahrain has functioned as a pioneer maritime trade center and represented a significant trade transit route between the east and west that transfers the affluent marine productions. This mainly formed an eminent cultural heritage for the country reflected within its inveterate maritime history and the authentic bond between the Bahraini grandparents and the sea. Unfortunately, along with the life evolution, this bond became weak and the biodiversity of the country’s marine …
