The Difference in the Mechanical Properties of the Limestone and Sandstone Rocks at Different Temperatures

EasyChair Preprint 13717

Abstract

A series of experiments were carried out to measure the influence of the heat and the saturation on the strength of the 2 types of sedimentary rocks (Limestone and Sandstone) at temperatures ranging between normal room temperature 22°C and 750°C using the Uniaxial compressive strength test and the Brazilian test after, and also the same process for the saturation group in the water. The drilling and cutting process took place in the first step, then the samples were distributed into several groups, each group faced a specific temperature, after that, exposure of the samples to the heat using the oven to reach the maximum temperature that was needed, the strength of each sample was measured according to the UCS and Brazilian Test. The results show that till 450°C both rocks resisted the temperature, but the limestone was much stronger than the sandstone, after increasing the temperature more than 450°C, the strength was strongly decreased. For the saturation group, the water harms the rocks, especially the limestone, and the decreasing strength is proportional to the density and the ultrasonic wave velocity. Because limestone and sandstone rocks are materials, the question is: Do their physical and mechanical properties change with high temperature? In this paper, we are going to answer this question for the limestone and sandstone rocks from room temperature to 750°C.

Keyphrases: Limestone, Sandstone, UCS and Brazilian test, Ultrasonic wave velocity, density, samples, weight
