A Review on the Impact of High-Temperature Treatment on the Physico-Mechanical, Dynamic, and Thermal Properties of Granite

Abstract

Temperature changes have significant effects on rock properties. The changes in properties vary for different rocks with different temperature ranges. Granite is an igneous type of rock that is common in India and is frequently used for construction and domestic purposes. Granite is mainly composed of quartz and feldspar and shows a considerable response to temperature changes and is the subject of this paper. A comprehensive review of the published literature has been conducted in this paper. Comparison of the findings of such works in terms of the impact of temperature changes on basic mechanical, physical, and thermal properties of granite, viz. thermal damage, density, p-wave velocity, compressive strength, peak stress, peak strain, and Young’s modulus from room temperature to 1000 °C has been conducted. The published data of different researchers have been utilized for such comparison. The study revealed that there is a significant departure in response to the rock recorded by various researchers, which may be due to the constitution of the rocks analyzed or experimental procedures. This points to the standardization of such tests. The main reason for changes in the properties of granite has also been discussed. Consequently, the findings of this state-of-the-art demonstrate that the heating effects of granite on its physical and mechanical properties become increasingly pronounced with increasing pick temperatures. The purpose of this article is to provide readers with an extremely well-structured, seamless environment that facilitates a critical assessment of granite in order to determine its thermal profile.
