reference of compressive strength of concrete paving blocks
Production and Characterization of Concrete Paving Blocks ...
After 28 days of curing (25 ± 1 °C and 65 ± 5 %), the paving block samples were tested for compressive strength according to the ASTM C936, using a 3000 KN servo controlled compression test unit, keeping the rate of loading constant at 13.5 KN/sec . The compression load was applied to the nominal area of paving blocks (200 mm × 100 mm).
