Effect of Formwork Characteristics on SCC Lateral Pressure
Bibliographic record
Abstract
Lateral pressure exerted on vertical formwork by fresh self-consolidating concrete (SCC) controls its design. Several factors, including material properties, placement conditions, and formwork characteristics, can affect formwork pressure. This paper presents the influence of formwork width (0.20–1.0 m), shape (circular versus square), and surface material (PVC, plywood, steel, and polyester filter membrane) of formwork on lateral pressure characteristics. The diameter of the pressure sensor used to evaluate lateral pressure characteristics is also investigated. The results showed that the increase in formwork width can increase the initial lateral pressure and delay the time needed for the formwork removal. Correction factors accounting for the changes in the formwork width on the initial pressure and pressure decay were developed. The formwork surface materials did show significant effect on initial formwork pressure, and different pressure decay responses were observed for each formwork material. The longest time for pressure cancellation was obtained for the steel formwork, and the shortest one for the polyester filter membrane.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
