An analysis of the abrasive wear of concrete floors has revealed that high-intensity crushing is the chief mechanism of deterioration, and hence the concrete crushing strength is the relevant parameter determining wear resistance. 248 Generally, the abrasion resistance of the coarse aggregate component is not related to the wear resistance of the concrete; rather, the properties of the mortar

🕑 Reading time: 1 minute Failure modes in reinforced concrete beams are classified into two major types: flexural failure and shear failure. The former occurs when the imposed load exceeds the flexural capacity of the materials of the beam, while the latter occurs due to deficiency in shear resistance between different materials of the beam.

The compressive strength of concrete measures its ability to resist forces trying to push the concrete together. The compressive strength of concrete is generally proportional to the volume of voids in the concrete matrix. Voids provide a shorter route for cracks to propagate through the concrete. These voids may be large air voids caused by poor placing or compaction, small voids introduced

Crushing strength of road stones may be determined either on aggregates or on cylinderical specimens cut out of rocks. These two tests are quite different in not only the approach but also in the expression of the results. Aggregates used in road construction, should be strong enough to resist crushing under traffic wheel loads. If the
