So, You Want To Build A Hangar?, Carla M. Fischer
So, You Want To Build A Hangar?, Carla M. Fischer
Purdue Road School
Driven by corporate growth, companies are buying, maintaining, and piloting their own fleets of planes. Companies need a place to store and care for these multi-million-dollar assets, so the demand for corporate hangars is growing. But hangars aren’t like other commercial buildings; they have distinctive features from other structures. This presentation will address how clients need to work with aviation designers to educate themselves on the distinct characteristics of hangars and construction in an airport environment.
Corrosion Performance Of Embedded Steel Bar In Cl--Contaminated Limestone Calcined Clay Cement (Lc3) At Initial Stage Of Hydration, Weiwen Li, Zuhua Xu, Yaocheng Wang, Xin Wang, Feng Xing
Corrosion Performance Of Embedded Steel Bar In Cl--Contaminated Limestone Calcined Clay Cement (Lc3) At Initial Stage Of Hydration, Weiwen Li, Zuhua Xu, Yaocheng Wang, Xin Wang, Feng Xing
International Conference on Durability of Concrete Structures
Limestone Calcined Clay Cement (LC3) presents brilliant properties in binding Cl- so that the embedded steel bars are probably protected in Cl--contaminated condition, which meets the need of sea sand application. However, the corrosion performance of steel bars embedded in LC3 paste with Cl‑ is unclear, especially in early age hydration. Thus, a series of experiments were carried out to evaluate the corrosion performance of steel bars on initial and hardened stages of hydration, including concentration of OH- and Cl- in real pore solution, open circuit potential (OCP) and chemical elements of steel bars. …
The Effect Of Initial Water Saturation On Freeze-Thaw Damage Of Submerged Mortar Materials, Siyuan Chen, Huigang Xiao
The Effect Of Initial Water Saturation On Freeze-Thaw Damage Of Submerged Mortar Materials, Siyuan Chen, Huigang Xiao
International Conference on Durability of Concrete Structures
An indispensable condition for the occurrence of the freeze-thaw (F-T) damage in unsaturated cement-based materials is that the specimens absorb water during the F-T process and reach a critical level of water saturation, which is influenced by the initial degree of water saturation (IDWS). However, the fast-freeze method commonly used in the laboratory does not reflect the effect of the IDWS on F-T damage. Thus, this study investigated the effect of different IDWS on the development of F-T damage in specimens to fill the gap in this research area. In this study, compressive strength tests were used to characterize the …

Latex Modified Concrete - Very Early Strength, Bobby Steele
Purdue Road School
INDOT came out with specifications for a very early strength concrete to use on bridge deck overlays. This concrete is fast setting, which allows overlays to be performed over a weekend and benefits the traveling public with a short duration of traffic interference. Cure time to reach the strength requirement is 3 hours. E&B Paving performed the first application with the new spec on August 26, 2018. Many changes were also made to the INDOT Specification Section 722.

High Performance Mortar With 100% Recycled Aggregate Using Titanium Dioxide Nanoparticles, Molly Schrager, Vito Francioso, Arjun Kadakia, Mirian Velay-Lizancos
The Summer Undergraduate Research Fellowship (SURF) Symposium
Concrete and mortar are materials commonly used in construction. Their main compounds are cement, aggregates (sand and gravel) and water. In an effort to increase the sustainability of these materials, the idea of using recycled aggregates from ground old concrete and using it to make mortar and concrete has gained more interest. It has two advantages: it reduces the need to mine for raw materials and lessens the amount of old and defective concrete that is typically put in landfills. But, the use of recycled concrete aggregate lowers the strength of mortars and concretes because the residual compounds in the …

Accessible Bike Share For The Midsized City, Caitlin Stevens, Zach Dripps
Purdue Road School
Bike share programs inevitably start in central business districts but often don’t reach neighborhood and core service destinations. How can bike share programs better serve communities? Michiana Area Council of Governments, partnering with the City of South Bend, launched a new dockless bike share program in July 2017 that aims to create a truly accessible network of bikes. Learn about the progress of the system and future plans for a complete regional system.

Learning And Becoming In Design Reviews, Lisa D. Mcnair, Marie C. Paretti, Cassandra Groen
Design Thinking Research Symposium
Drawing from the prior work of McNair and Paretti (2010), this study investigates how language practices and design artifacts mediate the interactions among novice and expert designers to shape the nature of design, and specifically design learning. By analyzing data collected from two design courses in different fields, this study addresses two research questions: 1) how do language practices mediate the interactions between design mentors and design learners; and 2) how do design artifacts mediate these interactions between mentors and learners? Drawing on activity theory and discourse analysis, we use these questions to explore how students work with experts to …

Absorption Simulation ( Absim ) Software Development, Vipul Vishnu Bhat, Ming Qu
The Summer Undergraduate Research Fellowship (SURF) Symposium
Researchers working on air conditioning systems currently use a software called ABSIM ( Absorption Simulation ) to evaluate current absorption systems or simulate new system designs. ABSIM was developed at Oak Ridge National Labs in the 1980s and the latest platform it is compatible with is Windows XP. ABSIM is not compatible on newer platforms and is not very user friendly. A lot of the actions involved in using ABSIM aren’t very intuitive. The goal is to develop a more user friendly simulation program that is based off of ABSIM and see to it that the program can be deployed …
Compression Testing And Failure Modes Of Steel-Concrete Composite (Sc) Structures For Nuclear Containment, Patrick Michael Wanamaker, Amit H. Varma
Compression Testing And Failure Modes Of Steel-Concrete Composite (Sc) Structures For Nuclear Containment, Patrick Michael Wanamaker, Amit H. Varma
The Summer Undergraduate Research Fellowship (SURF) Symposium
Although being able to provide much cleaner power than burning coal and other fossil fuels, nuclear power plants are still a tough sell to the general public due to their history of being spontaneously dangerous. The containment structures surrounding these nuclear plants, however, can play a huge role in reducing the risks associated with them. Relatively new designs for these containment assemblies, known as SC (steel-concrete composite) structures, aim to increase the strength and durability of the containment facilities while keeping costs down. By varying the spacing between shear studs, the ratio of concrete to steel, and the ratio of …
Environmental Monitoring In Preparation For The Installation Of A Green Roof, Andrew N. Martin, Ming Qu
Environmental Monitoring In Preparation For The Installation Of A Green Roof, Andrew N. Martin, Ming Qu
The Summer Undergraduate Research Fellowship (SURF) Symposium
Green roofs are becoming an increasingly popular way to improve the environmental, economic, and aesthetic performance of both new and existing buildings. Along with the green roofs themselves, it is also common to install sensors to measure various environmental parameters that are affected by or important to the operation of the roof such as precipitation, temperature, and runoff. However, for most of these systems, the sensors are installed at the same time or even after the green roof. Therefore, no before-and-after comparisons can be made for those roofs. To account for this missing data, monitoring equipment was installed on a …
