Cement Mortar Properties Contain Crumb Rubber Treated with Alkaline Materials
Bibliographic record
Abstract
In the present work, the properties of rubberize cement mortar are treated with alkaline materials and tested and compared with normal rubberize and normal cement mortar. The rubber, which is treated with different alkaline materials such as: (NaOH, NaOCL, and Commercial detergent powder) of high pH (13-14), is used as partial replacement for sand in cement mortar. The percent of replacement ranged from 15 to 35%. Compressive strength, flexural strength, and modulus of elasticity are also tested for rubberize cement mortar, rubberize cement mortar treated with alkaline materials, and normal cement mortar. The results show that the treatment of rubber with alkaline materials significantly improves the properties of cement mortar. Moreover the results also show that NaOCL gives better improvement more than NaOH, while commercial detergent powder shows negative effects on all cement mortar properties.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
