Temperature variations in concrete bridges
Web4 Oct 2024 · Concrete is best laid at temperatures that are between 5 degrees Centigrade and 40 degrees Centigrade. Any temperatures more than this or lower than this needs special attention to the temperature of … Web13 Apr 2024 · Eight of the thermistors are mounted in the walls and four are mounted in the base. The thermistors are connected to a Wheatstone half bridge and digitized using a custom-built Arduino board. The resistance of the thermistors is nonlinear over a wide temperature range (∼−15–17 °C), and each thermistor is calibrated over the full range.
