2010-8-7 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 fraction are

2020-4-17 Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures. Compressive strength of concrete depends on many factors such as water-cement ratio, cement strength, quality of concrete material, quality control during the production of concrete,

2014-4-20 The compressive strength of the concrete cylinder is one of the most common performance measures performed by the engineers in the structural design. Here, the compressive strength of concrete cylinders is determined by applying continuous load over the cylinder until failure occurs. The test is conducted on a compression-testing machine.

Compressive Strength The main measure of the structural quality of concrete is its compressive strength. This property of concrete is commonly considered in structural design. Depending on the mix (especially the watercement ratio) and time and quality of the curing, compressive strength of concrete can be obtained up to 14,000 psi or more.
