Testing Of Accelerated Pozzolanic Activity Of Fly Ash, Anne Oberlink, Tom Robl, Bob Jewell, Haley Johnson

World of Coal Ash Proceedings

The determination of the pozzolanic reaction in fly ash by ASTM strength activity index has been shown to be problematic, frequently producing false positives. The use of Wenner probe resistivity has been demonstrated to be rapid, simple and non-destructive method, producing no false positives. However, using this method and confirming it with other techniques finds that the reaction itself is slow with a dilatancy of 28 days or more before the measurements become discriminatory, a major drawback to this method. This study used high-temperature, high humidity curing of OPC-based mortars with various fly ash sources to determine how pozzolanic activity …

Reverse Osmosis; Addressing Freshwater Shortage With Sustainable Desalination, Jessica Savage

Sustainability Conference

Water security is an imperative part of high-functioning societies. Currently, large populations of the globe live in water-impoverished or water-stressed areas. With climate change and growing global populations, projections show more people being impacted by issues of water shortage.

One solution to water security is the implementation of desalination, specifically with reverse osmosis systems. This presentation walks through the history, capabilities, future work, and explanations on how reverse osmosis systems work. With continued research on improving desalination, communities in both developed and developing nations around the world can work towards total water security.

Background- Photovoltaic (PV) cells produce the largest amount of electricity when they are directly facing the sun. Solar panels that use tracking systems to position the panel to constantly face the sun have the greatest efficiency. But, these systems are expensive.

Aim- Design a dual axis tracking solar panel with microcontroller and sensors (light, humidity, temperature, and compass) that are both cost effective and efficient. Sensors will be used to determine performance depending on environmental factors.
