Table 3 Rheological properties of RHC and limit values according to UNI 11040 for (SCC)
From: Flexural performance of rapid-hardening concrete (RHC) beams with tension lap splice
Test | Test results | Limits value | Notes |
|---|---|---|---|
Slump flow | D = 750–770 mm | D > 600 mm | D: refer to the diameter of concrete at the end of the test after 90 min = 750 |
L-box | H2/H1 = 1.1 | H2/H1 > 0.8 | H2, H1: refer to the height of concrete after and before entering the L—box gate |
U-test (T0) | 9.8 | 6–12 s | T: refer to the time of concrete to pass through U-test |
U-test (T5) | 12.1 | T0 + 3s | Second U-test |
