QUANTIFICATION SYSTEM FOR SPALLING IN CONCRETE USING GRAIN SIZE ANALYSIS AND METHOD FOR THE SAME

摘要

By analyzing the grain size of the exploding debris of the concrete structure caused by the fire and quantifying the spalling, the explosive phenomenon can be expressed more concretely and numerically. In addition, the destruction pattern at room temperature and the high temperature due to external force By analyzing the correlation between the failure modes, it is possible to predict the explosion at high temperatures based on the destruction caused by the external force.In addition, the reduction or non-occurrence conditions and management measures can be quantitatively specified through the quantification of the explosion. Accordingly, a concrete explosive quantification system using particle size analysis and a method thereof that can secure economic feasibility by further systematizing concrete mixing and curing conditions and subsequent management plans at the site are provided.
