Self-Heating Concrete Paves the Way for Easier Winters (Source: Oil Price on 24 March 2024): By Brian Westenhaus - Drexel University researchers recently reported on the science behind its special concrete, that can warm itself up when it snows, or as temperatures approach freezing. In a paper published in the American Society for Civil Engineering’s Journal of Materials in Civil Engineering, the group took the important step of proving its viability in the natural environment. There’s a patch of concrete on Drexel University’s campus that could portend a frost-free future for sidewalks and highways in the Northeast. Tucked inconspicuously next to a parking lot for the university’s facilities vehicles, two 30-inch-by-30-inch slabs have been warding off snow, sleet and freezing rain on their own – without shoveling, salting or scraping – for a little over three years. ...
MIT Engineers Develop Groundbreaking Concrete Supercapacitor (Source: Oil Price on 5 August 2023): By Brian Westenhaus - MIT engineers have created a supercapacitor from just cement, water, and carbon black. The supercapacitor is made of ancient, abundant materials, that can store large amounts of energy. The device could form the basis for inexpensive systems that store intermittently renewable energy, such as solar or wind energy. According to a new study two of humanity’s most ubiquitous historical materials, cement and carbon black (which resembles very fine charcoal), may form the basis for a novel, low-cost energy storage system. The technology could facilitate the use of renewable energy sources such as solar, wind, and tidal power by allowing energy networks to remain stable despite fluctuations in renewable energy supply. The researchers found the two materials can be combined with water to make a supercapacitor – an alternative to batteries – that could provide storage of electrical energy. As an example, the MIT researchers who developed the system say that their supercapacitor could eventually be incorporated into the concrete foundation of a house, where it could store a full day’s worth of energy while adding little (or no) to the cost of the foundation and still providing the needed structural strength. The researchers also envision a concrete roadway that could provide contactless recharging for electric cars as they travel over that road. ...
