2013-10-1 Uniaxial compressive strength value (UCS) is used as a critical input parameter in determining the engineering properties of natural building stones. The purpose of present study was to develop a model to determine the UCS of natural building stones via relatively simple and low-cost mechanical tests with the application of artificial neural networks.

2021-4-27 Uniaxial compressive strength (UCS) is one of the most important mechanical properties of natural stones to determine their usability for outdoor applications especially in cold regions (Bayram 2012; Yurdakul and Akdas 2013). Although much research has been done on the deterioration of UCS during freeze–thaw cycles, a few predictive models have been developed for the prediction of UCS of building stone

2021-7-24 Compressive Strength: It is also sometimes referred as crushing strength of a stone and may be defined as the maximum force expressed per unit area, which a stone can withstand without rupturing. Any force applied beyond the compressive strength will cause a failure or rupture of the stone.

Uniaxial compressive strength (UCS) is a significant mechanical parameter for rock abrasiveness, which affects the cutting operation performance of the building stones and functions as the reliable basis for the selection of the cutting materials as well , , . Moreover, a lot of civil structures, such as dams, bridges, tunnels, have been constructed with building stones.

2012-3-1 Compressive behaviour is influenced largely by porosity. Analytical model describes the compressive mechanical behaviour of building stones. This model is well defined by a cubic polynomial function. A good agreement between the analytical and experimental results was found. Mechanical properties can be estimated without DT of samples.

2021-6-28 Natural building stones are widely used in the construction field in the Middle East and Mediterranean areas. Stones are chosen for their durability, attractiveness, and low cost compared to other construction materials. Building stones come with different natural origins and vary in their mechanical and thermal characterizations. Compressive strength, water absorption, and thermal ...

2012-9-1 From this figure, there is a noticeable relation between rebound number and compressive strength. For all types of studied stones, compressive strength increases as rebound number increases. Linear model and non-linear model were suggested for each type of stone. Linear model was chosen because it is a simple model and it was suggested by others .
