Abstract
It is desirable to completely recycle concrete waste in order to protect natural resources and reduce environment pollution. In this paper, the studied reference mix composed of demolished waste concrete/grog/hydrated lime in the ratio of (40/50/10, wt. %), while other mixes has cement kiln dust as a partial replacement of hydrated lime in the ratio from zero up to complete replacement. Both grog and burned cement kiln dust were obtained from firing clay materials as well as by-pass cement kiln dust at 850°C for 1 h with a heating rate of 5°C/min. Results of this study possess a method for recycling of demolished wastes in brick making as fine materials not in the traditional method that used it as aggregate. Waste concrete, grog, hydrated lime and by-pass cement dust can be used instead of the cement constituent of mortar and hydrated building brick making. Key words: Demolished concrete, cement kiln dust, grog.

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 it
