Strength of Limestone In mechanics of materials, the strength of a material is its ability to withstand an applied load without failure or plastic deformation. Strength of materials basically considers the relationship between the external loads applied to a material and the resulting deformation or change in material dimensions.
To study the effect of high temperature on the dynamic mechanical properties and energy evolution characteristic of limestone specimens, the basic physical parameters of limestone specimens that cool naturally after experiencing high temperatures of room temperature (25°C), 200°C, 400°C, and 600°C were tested.
In the current work, experiments were conducted to simulate the reaction process of CO 2, seawater and reef limestone to investigate the destruction of both the physical and mechanical properties of reef limestone due to the acidification of seawater. The solution was analyzed for dissolved Ca 2+ concentration during the reaction.
The results indicate that, from room temperature to 300°C, most of the physical and mechanical indices of limestone and marble change relatively little, except for thermal diffusivity. Above 300°C (especially at 400–600°C), physical and mechanical characteristics change significantly, corresponding to the changes to minerals between 400 and 600°C.
At 25 °C limestone concrete provided a tensile strength of 2.47 MPa while the same for quartzite and granite concretes was 3.14 and 3.99 MPa (27 and 62 % higher), respectively. At 650 °C the tensile strength of limestone, quartzite and granite concretes was 0.60, 0.95 and 1.77 MPa, respectively.
