## Accep Le Crushing Strength Limit For M Grade Concrete

#### HighStrength Concrete

HighStrength Concrete. In the early 1970s, experts predicted that the practical limit of readymixed concrete would be unlikely to exceed a compressive strength greater than 11,000 pounds square inch (psi). Over the past two decades, the development of highstrength concrete has enabled builders to easily meet and surpass this estimate.
