Abstract
In this study, alkaline activated binder pastes were produced from high calcium fly ash and copper slag in different combinations. The blends were activated with soda ash (sodium carbonate) as the alkaline activator to effectively optimize each materials component in the development of the binder. The as-received samples and the hardened fly ash-copper slag paste were characterized using X-ray Diffraction, X-ray Fluorescence for chemical phase and elemental composition. The mechanical properties were determined by compressive strength test on the hardened cubes produced from resulting pastes at 3, 7, 28 days kept under varying curing conditions. The results show the effects of blend ratio, variation in individual material composition, and curing conditions at different activator dosages on compressive strength of the fly ash-Copper slag activated pastes. From the compressive strength tests result, the optimum composition for fly ash and copper slag was 60% and 40% respectively. Increase in soda ash dosage and curing temperature also increased material strength.

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
