Abstract
In this study, the changes in the index and strength properties of calcarenites, which are widely used as building stone in the Turkish Republic of Northern Cyprus, after being subjected to high temperatures between 200 and 1000oC, and the effects of high temperatures on microstructure of the calcarenite were investigated by using electron microscope images. In order to represent a real fire incident, the samples were heated using the temperature-time curves recommended by Eurocode, and left to cool at room temperature after 2 hours of exposure at target temperature. After the experimental studies, it was observed that there was no significant change in density and weight loss values up to 600 oC. After 600 oC, a sudden decrease in density was recorded, at 1000 oC the density dropped below 1 due to Yüksek Sıcaklıklara Maruz Kalan Kalkarenitlerin Fiziksel ve Dayanım Özelliklerindeki Değişimin Araştırılması Investigation on the Change of Physical and Strength Properties of Calcarenite Exposed to
本研究利用电子显微镜图像，研究了北塞浦路斯土耳其共和国广泛使用的建筑石材方解石在经受200 ~ 1000℃高温后的指标和强度性能的变化，以及高温对方解石微观结构的影响。为了表现真实的火灾事件，使用欧洲规范推荐的温度-时间曲线对样品进行加热，并在目标温度下暴露2小时后在室温下冷却。经过实验研究，发现在600℃下，密度和失重值没有明显变化。600℃后，密度突然下降，在1000℃时，由于 ksek Sıcaklıklara Maruz Kalan Kalkarenitlerin Fiziksel ve Dayanım Özelliklerindeki Değişimin Araştırılması作用，密度降至1以下
