High-Strength Concrete. In the early 1970s, experts predicted that the practical limit of ready-mixed 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 high-strength concrete has enabled builders to easily meet and surpass this estimate.

The crashing strength ranged from 0.120 MPa to 0.920 MPA as shown in Table 4. This indicates that all bricks had crushing strength less than 0.103 MPA the minimum required crushing strength for a construction brick (Dutta, 1998). It is also observed that some bricks had higher crushing strength than that of cement-sand blocks samples.
