Example Embodiment
[0032] Embodiment 1: raw material and proportioning are as follows
[0033]
[0034] Table 1 Proportion of high belite sulphoaluminate cement-based anti-disturbance concrete 1
[0035] The following is the test report of the obtained high belite sulphoaluminate cement-based anti-disturbance concrete for emergency repair
[0036] Test items
[0037] The disturbed period of the anti-disturbance concrete under this ratio is only 8 minutes, which reduces the probability of concrete being disturbed; there is no crack on the surface of the test piece; the early and late strength performance is excellent, and the compressive strength can reach 20.2MPa 2h after being disturbed. The flexural strength can reach 6.3MPa, and there is no loss of strength compared with the undisturbed test piece, which meets the technical requirements for quick repair and opening to traffic.
