Abstract

fetched live from OpenAlex

Autogenous shrinkage is the main driving force for internal deformations in ultra-high performance fibre-reinforced concretes (UHPFRC). Autogenous deformations and viscoelasticity are determined with free and restrained shrinkage tests for one kind of UHPFRC at an early age. The magnitude of free autogenous shrinkage is very strong during the first hours after hardening with 150 μm/m at 48 h and 325 μm/m at seven days. Long-term tests show that autogenous shrinkage becomes virtually constant at 90 days. The creep deformations of the fully restrained test amount to 60% of the free shrinkage deformations. Another experimental programme conducted on composite ‘UHPFRC–concrete’ beams shows that their time-dependent deformations are strongly influenced by the autogenous shrinkage of UHPFRC; however no visible cracking is induced in the structural elements.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
