    201484&ensp·&enspLimestone is usually found in horizontal beds formed from lithified sediments consisting of mostly calcium carbonate. Limestone beds are often interrupted by shale layers. Limestone can vary from being soft and brittle to very hard and dense depending on the amount of clay or sand.

  • Cohesion degradation and friction mobilization in brittle

    Parametric studies showed that increasing initial and residual values of cohesion and friction angle limits the depth and angular extent of failure zone. Finally, general guidelines were suggested for estimating the parameters of the proposed model for in situ brittle failure of good quality rock masses.

  • Rock Brittleness Prediction Using Geomechanical Properties

    The cold climate is a favorable parameter for the development of tension cracks and decrease of rock brittleness. Therefore, this paper attempts to investigate the Hamekasi porous limestone in order to predict the brittleness indices during freezethaw cycles. The freeze–thaw test was executed for one cycle including 16 h of freezing, and 8 h of thawing.

  • Brittle dolomite vs. limestone Petroleum engineering

    The theory is that the dolomites are more brittle then the limestone, and tectonic events which deform (i.e., ductile behavior) the limestone will fracture the dolomite (i.e., brittle behavior), creating superK intervals. I've tried a few of the available web sites for civil engineering, but
