Cracking Tendency of Krenit Fiber Reinforced Concrete Exposed to Plastic Shrinkage
The report presents the results from an investigation on the influence of plastic fiber reinforcement on the plastic shrinkage and cracking tendency of concrete exposed to early drying. 8 types of Krenit fiber have been investigated. The results reveal that they all have a considerable crack reducing effect, which increases with increasing fiber dosages. An addition of 1 kg fiber per m sup 3 gave a crack reducing effect that varied considerably with the type of fiber used. However, at additions of 3 kg per m sup 3 no significant differences were observed for the different fiber types, which all gave more than 90 percent crack reduction at this dosage. One of the fiber types was also added in dosages of 5 and 10 kg per m sup 3, respectively. At both these dosages the result was a complete elimination of the crack formation.
