Quantitative Relationship Between Concrete Neutralization Depth and Its Influence Factors

The concrete is a very common building material. It is widely used because of its good fire safety, low cost, convenient production process and no pollution to the environment. According to the pyrolysis process and mechanism of concrete, muffle furnace experiments were conducted. By studying the quantitative relationship of concrete's neutralization depth and its influence factors the paper establishes a mathmatical model of calculation neutralization depth, hoping to provide a reference for future fire investigation.
