Rock Mechanical Properties of Granite/ Clay/ Basalts/ Argillite / Glass and its Alterations at Different Temperatures-A Review

Abstract

This paper presents a review of the effect of temperature in altering the rigid mechanical properties of materials like granite, clay, basalt, argillite and glass. Mechanical properties such as elasticity, stress, porosity, tensile strength and permeability of the materials were analysed at various temperatures. The analysis highlights the results and conclusions derived from numerous experimental works like tri-axial compression test, uniaxial test, etc. Apart from this, the impact of temperature on physical characteristics like colour, porosity, wave propagation and density were also studied. The main feature of this study is to showcase the acceptable range of temperature of the materials so as to avoid cracking and breaking of the materials during engineering applications. Moreover some back up techniques have been suggested to enhance the quality and strength of the materials.

Experimental and Theoretical Investigations of Hard Rocks at High Temperature: Applications in Civil Engineering

“…Diaz [2] performed experiments on three different rock types (marble, limestone, and sandstone) and confirmed this similar characteristic behavior of Young's modulus. Indeed, some results obtained were quite dispersed but can be explained by the heterogeneity of different rocks on the one hand and the experimental conditions and parameters on the other hand.…”

“…In the same year, Soprani et al [26] investigated a combination of bottom steam cycles with high temperature thermal energy storage systems as potential cost-effective alternatives to traditional large-scale energy storage technologies. After thermal treatment, they demonstrated using different rock bed configurations that a storage capacity of 450 kWh enabled to have 600°C at certain positions [2]. However, their results showed that in charge and discharge cycles, the efficiency of the best configurations was about 68%.…”

“…e behavior of these rocks in thermal loading remains relevant. High temperature is an important factor in geotechnical engineering and its applications, especially in rocks, underground excavation for deep mining and caverns, geothermal energy resource exploration, underground nuclear fuel storage, underground coal gasification, and constructional projects such as pavements, exterior decorations, roads, and tunnels [1,2]. On the other hand, an increase in temperatures in public civil structures, buildings, and others due to fire leads to pay attention about its impact on the lifetime of these structures.…”

“…e importance of this area in everyday life is well established and reflected the fact that the behavior of aggregates and concretes subjected to high temperature is still an issue of great importance that requires an in-depth scrutiny. At high temperature it is known that, the aggregates break down and undergo important physicochemical mineral changes, which essentially change the microstructural characteristics of the material [1][2][3]. Aggregates are generally composed of minerals optionally a matrix and include cracks, pores, and fluids inclusions.…”

“…In 2017, Diaz [2] reported an experimental study review on the temperature effect in altering the rigid mechanical properties of materials like granite, clay, basalt, argillite, and glass.…”
