Data from structural testing of sprayed and cast shotcrete reinforced with fibres of steel, basalt and synthetic material

Description

In this dataset, data from experimental testing of fibre-reinforced shotcrete is presented. The dataset contains results from four different fibres made of steel (Dramix 3D and Dramix 4D), synthetic (BarChip R54) and basalt (MiniBar). Preparation of specimens and testing were performed by Vattenfall R&D in Älvkarleby, Sweden. This second version of the dataset contains the results for shotcrete specimens prepared through casting and spraying. The same shotcrete mix was used for all specimens, and three different dosages were used for each of the fibres. The dataset contains the shotcrete mix and standard output for the test of compressive strength according to EN 12390-3, residual flexural strength according to EN 14488-3 and energy absorption according to ASTM C1550. Raw data, i.e. force-displacement curves from testing, are also available. This dataset can be used to study how the structural performance of fibre-reinforced shotcrete is affected by the dosage of fibre. Moreover, the data can be used to verify and tune non-linear material models using the finite element method. The data also provide a foundation to select a reasonable dosage of fibres to fulfil the structural requirements put on shotcrete in the design phase. A data paper entitled "Dataset for evaluation and numerical modelling of structural performance of fibre-reinforced shotcrete with fibres of steel, synthetic and basalt" is currently under review in Data in Brief and, if accepted, a link to the paper will be added here for a more thorough description.
