Szukana fraza: [Abstract = "Exposure of concrete to high temperatures affects its mechanical properties by reducing the compressive strength, bending...etc. Factors reducing these properties have been focused on by several studies over the years, producing conflicting results. This article interested an important factor, that is the type of aggregates. For this, an experimental study on the behavior of concrete based on different types of aggregates\: calcareous, siliceous and silico\-calcareous subjected to high temperatures."]
