Experimental study on durability of basalt fiber concrete after elevated temperature

The durability of concrete material after exposure to elevated temperatures is important for the serviceability prediction structures in a fire disaster scenario. Existing researches show that an appropriate amount basalt fiber can significantly improve splitting tensile strength and chloride penetration resistance concrete. However, mechanical properties its are still not clear. In this paper, properties, carbonization law, ion law ordinary under high studied. concept burnt layer exposed proposed, thickness different was measured. results addition inhibit at temperatures, diminish layer,
