A total of 276 CPB were fabricated and tested in laboratory to determine the density, skid resistance and the compressive strength. The design strength level ranging from 31 to 43 MPa was achieved using w/c ratios of 0.45 to 0.55. The test results indicated that there was a systematic reduction in the strength with the increase in rubber content.

Bullnose concrete blocks are the same as concrete pillar blocks. The only minor difference is that they have rounded edges. Thus, if you prefer rounded edges, bullnose concrete blocks are the right option for you. Source: The constructor. Paving Blocks. Paving blocks are square or rectangular shaped boxes made from reinforced concrete.
