2017 Guide for Limestone Tile Pros and Cons - Sefa Stone

Limestone is a soft stone as compared to other natural stones meaning it can be cut into the size of your choice so whether it is small size floor tiles or a mosaic design made of really small chunks of limestone all of this is achievable because of the softness of limestone.

Limestone mechanical deformation behavior and failure ...

Gen- erally, Mohr–Coulomb is used for limestone brittle fracture. The characteristic of low temperature cataclastic flow and the conditions and constitutive equations of intracrystal plastic deformation such as dislocation creep, diffusion creep, and superplastic flow are discussed in detail.

Effect of clay content. Clays are a very common component and can make up anywhere from 0 to nearly of a clastic rock. Usually, at some point greater than 40% clay, the rock is considered a shale or mudstone rather than a sandstone (refer to Gamma ray as a tool for rock characterization ).

Brittle and Semi‐brittle creep of Tavel limestone deformed ...

In this study, the mechanical behaviour of a limestone with an initial porosity of 14.7 % is investigated at constant stress. At confining pressures below 55 MPa, dilatancy associated with micro-fracturing occurs during constant stress steps, ultimately leading to failure, similar to creep in other brittle media.
