Introduction Most of the buildings in Taiwan are constructed of concrete. Even so, lives and assets are lost to fires. Apart from blemishing the outer appearance of buildings, fire chemically and physically compromises concrete structures. It is important, therefore, to perform a safety assessment of concrete structures after fire and to understand the behavior of concrete at high temperature. There is a vast body of literature about the fire resistivity of concrete. In recent years, especially in the aftermath of the “921 Earthquake”, an enormous amount of scrap from demolished buildings, most of which is waste concrete, has been generated. Increasing levels of awareness about environmental protection have meant that recycling is now favored over disposal to landfill and accordingly, the effective recycle of waste concrete would be of great help to the environment. Previous studies show that recycled concrete tends to have lower elastic modulus, higher porosity, lower strength and lower durability than new concrete. Recycled concrete also differs from natural aggregate concrete in terms of fire resistivity and mechanical behavior after fire. There is little current literature on the fire resistivity of recycled concrete, which makes this study necessary. 2. Experimental Materials and Program 2.1 Experimental Materials Here is a list of materials adopted by this study: 1. Conventional cement: Portland cement type I from Taiwan Cement Corporation with a density of 3.15; 2. Natural coarse aggregates: broken stone provided by Concrete Mixing Plant located in Lujou, Taipei. 3. Waste concrete from laboratory: waste concrete that was derived fr
