Influence of backfill on coal pillar strength and floor

A 10–40% increase in pillar strength and ultimate bearing capacity can be expected when a cohesive fill is used between 25 and 75% fill of the mined height, respectively. The non-cohesive nature of the simulated backfill showed little influence on increased pillar strength, even at higher fill ratios.

What is Compressive Strength?- Definition, Formula

Compressive strength is a limited state of compressive stress that leads to failure in a material in the manner of ductile failure (infinite theoretical yield) or brittle failure (rupture as the result of crack propagation, or sliding along a weak plane). Compressive strength is measured on materials, components, and structures.

The comparative study of the compressive strength of

Granite with 28days of arising had a compressive strength of 45N/mm, river round stone was 36N/mm2 and that of local stone 18N/mm2. And this shows that granite has a greater strength than river round stone and local stone, which was mainly attributed to greater void spaces in river round stone and also in local stone.

Factors affecting the compressive strength of the concrete

It is the most important factor for gaining the strength of concrete. The lower w/c ratio leads to a higher strength of concrete. Generally, the water/cement ratio of 0.45 to 0.60 is used. Too much water leads to segregation and voids in concrete. The water/Cement ratio is inversely proportional to the strength of concrete.
