Three groups of concrete samples of C30 class were prepared with antifreeze admixtures by using the mixture of 30% calcium nitrate and 5% hydroxy ethoxy amin (A), calcium nitrate (B), Polyhydroxy amine (C). <span style="mso-spacerun: yes;">  </span>Concrete samples are put in the freezer in a fresh state 15 min after the mixing. Samples are subjected to frost action in 0, -5, -10, -15 and -20°C degrees for 48 hours. On the concrete samples water cured after 48 hours, compressive strength tests of 28 day are conducted. Consequently, it is seen that with the increase of the set temperature that concrete is cured, compressive strength of concrete is decreased and among all types of antifreezes the maximum decrease is seen between 0 and -5°C while the decrease in compressive strength is relatively less for -10, -15 and -20°C. </span> </p> <p class="MsoNormal" style="text-align: justify; margin: 0cm 44.9pt 0pt 54pt;">  </p> <span style="font-size: 8pt; mso-bidi-font-weight: bold;" lang="EN-US"> <p class="MsoNormal" style="margin: 0cm 44.9pt 0pt 54pt; text-align: justify;"> <strong> <em style="mso-bidi-font-style: normal;"> <span style="font-size: 8pt;" lang="EN-US">Keywords: </span> </em> </strong> <em style="mso-bidi-font-style: normal;"> <span style="font-size: 8pt; mso-bidi-font-weight: bold;" lang="EN-US"> Antifreeze, concrete production in cold weather, compressive strength. </span> </em> </p> </span> <p class="MsoNormal" style="text-align: justify; margin: 0cm 44.9pt 0pt 54pt;"> <span style="font-size: 8pt; mso-bidi-font-weight: bold;" lang="EN-US">  </span> </p> <p class="MsoNormal" style="text-align: justify; line-height: 150%; margin: 0cm 0cm 0pt;">  </p> </span> </span> </span>}, number={2}, publisher={Gazi University}
