They also have much higher compressive strengths than the concrete mix you are thinking of using. |
High-strength concrete, that is, compressive strengths of 12,000 to 14,000 psi, doesn't need air-entrainment, but it is often specified anyway. |
This compressive stress would be the longitudinal analog of the ridge push stress which helps drive plate motion. |
The granularity of sand and water content have great effect in the increase of compressive stresses. |
The caissons, with concrete compressive strengths of 5000 to 6000 psi, were in good condition and are being reused. |
The results of field and laboratory testing indicated that the compressive strength of the silty clay ranged between 0.5 to 2 tsf. |
