Investigation of High Temperature Effects on Concrete Additive Antifreeze
Journal Title: Aksaray University Journal of Science and Engineering - Year 2018, Vol 2, Issue 1
Abstract
The purpose of this work is to determine the effect of the antifreeze additive on the behavior of the concrete under high temperature. For this purpose, two different types of C20 class concrete were produced with reference and antifreeze additive. 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. 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.
