A methodology for determining crushing strength of

Researchers, in general, resort to crushing strength tests to determine the strength gain by stabilized waste with curing period. However, these tests are not only destructive in nature, but also require testing of several identical samples and sample preparation, which is manually done, is cumbersome.

Influence of manufactured sand characteristics on strength

Resulted show that the increment of limestone microfines amount in MS from 4.3% to 20% by mass increases the compressive and flexural strengths and improves the abrasion resistance of the MS-PCC. The MS-PCC has higher compressive and flexural strengths when the surface roughness of the sand particles is larger and the crushing value is lower.

Effect of Concrete Strength and Slab Thickness on Floor

Mar 01, 2001· The average core length was 5.62 inches, and the average strength was 5580 psi. Is the higher-than-specified strength enough to compensate for the lower-than-specified floor thickness? A.: Most designers calculate the required thickness of a floor based on the flexural strength of the concrete.
