The use of fibers was found to be very effective not only in reducing the widths of the shrinkage cracks but also in allowing multiple cracking to occur. Interestingly, these two phenomena occurred only up to a fiber volume fraction of 0.5%; at 1% by volume of fibers, only minimal cracking was seen to occur even under a particularly severe ...

2017-5-3  Modern tunnels in hard rock are usually constructed by drill and blast with the rock reinforced by shotcrete (sprayed concrete) in combination with rock bolts. The irregular rock surface and the projection method of shotcrete lead to a tunnel lining of varying thickness with unevenly distributed stresses that affect the risk of cracking during shrinkage of the young and hardening material.
