Abstract

In the present paper, a numerical investigation aimed at determining the significance of temperature distribution, pore pressures, and thermally induced stresses for spalling of concrete under fire conditions is performed. In this paper three types of concrete are evaluated: concrete with quartz aggregate, concrete with limestone aggregate, concrete with basalt aggregate. All of these aggregates are abundant in our country and are used in concrete admixtures. Results show that spalling in Quartz-based concrete is higher than others and this concrete exposes to decreasing in strength under fire in comparison to others, and increasing concrete segment depth or adding the specified amount of polypropylene fiber in concrete mix can improve the fire performance of concrete pieces.
