effect of the antifreeze additive on the behavior of the concrete under high
temperature. </span> <span style="font-size:12pt;line-height:115%;font-family:’Times New Roman’, serif;">  <span style="color:rgb(33,33,33);">For this purpose, two different types of C20 class concrete
were produced with reference and antifreeze additive. </span> <span style="color:#212121;">Fresh concrete was poured into plate molds, after 14 days
standard curing, core samples of Ø5x10 cm dimensions were taken from plaque
concrete. On day 90, the core samples were exposed to temperatures of 20, 200,
400, 550 and 700 °C for 3 hours and they cooled by air and water spray.
Experiments on water absorption, ultrasound transit speed and compressive
strength were carried out on the core samples. Microstructures were analyzed by
X-ray diffraction method in concrete specimens applied at temperatures of 20
and 700 °C. </span> </span> <span style="font-size:12pt;line-height:115%;font-family:’Times New Roman’, serif;color:#212121;"> </span> <span style="font-size:12pt;line-height:115%;font-family:’Times New Roman’, serif;color:#212121;">As a result, it has been
determined that the concrete with antifreeze strain that is least affected by
the temperature of 700 °C is cooled water. </span>}, number={1}
