摘要
Previous experimental studies on concrete under high temperatures have mainly concentrated on the reduction of stiffness and strength properties. Various experimental parameters have been examined such as maximum temperature, heating rate, types of aggregates used, various binding materials, and loading paths (that is, mechanical loading applied before, during, and after high temperature testing). There exist few data on strength, stiffness, and permeability of concrete considering cooling rate after fire damage, however Particularly, the increase of permeability severely affects the durability properties of concrete and reduces the remaining service life of the concrete structure. The purpose of this study is to investigate strength, stiffness, and permeability properties of concrete cylinders that are subjected to various heating and cooling scenarios. The thermal diffusivity, weight losses, color changes, and cracks of the specimens are also reported
