Hemp Fiber Concrete Properties and ANN Modeling
A study on hemp fiber-reinforced concrete evaluates fresh and mechanical properties across 11 dosage levels (0–2.0% by volume).

01Summary
Compressive strength peaks at 0.6%, while splitting tensile and flexural strengths peak at 1.2%. A multi-output ANN model predicts strengths with low RMSE, outperforming single-output models but not surpassing cubic splines. Workability decreases significantly with fiber content, from 95 mm slump to 40 mm.
