Evaluation of the Flow Table Method for Analyzing the Rheology of Concrete with Fibers
The reinforcement of cementitious matrices with structural fibers in concrete production imposes restrictions on the workability of fresh concrete compared to that without fiber addition. Several international standards have sought to develop and evaluate better methods for this technology. In Brazi...

| description | The reinforcement of cementitious matrices with structural fibers in concrete production imposes restrictions on the workability of fresh concrete compared to that without fiber addition. Several international standards have sought to develop and evaluate better methods for this technology. In Brazil, the most recent standards have continued to analyze the workability of concrete using the traditional slump test method. This work, which investigated three different types of fibers in three different dosages, shows that the flow table method can be better used to measure the effect of different levels and types of structural fibers in concrete. The results showed that when plastic concrete receives the addition of fibers, its workability is little changed under energy, which is the principle of the flow method and the practical application using vibrators, but there is a loss of this property when measured using the traditional slump test method. When this workability was corrected using the slump test method, the water content of the concrete mixes increased. The comparative results showed that the analysis of the impact of structural fiber dosage by combining the two methods can support the development of concretes using only the slump test method. |
