BIOMANUFACTURING OF HIGH-STRENGTH CONCRETE: INCORPORATION OF HEMP FIBER TO IMPROVE HIGH-TEMPERATURE PERFORMANCE

Objective

The goal is to biomanufacture high-strength concrete by adding waste hemp fibers, which will increase its stability at high temperatures. The objectives are: i) Identify and source hemp plants with geographically diverse genetics; ii) Process, treat, and characterize hemp fibers for incorporation in high-strength concretes; iii) Formulate hemp fiber-reinforced high-strength concrete (HFR-HSC) mix designs with optimal hemp fiber dosage; iv) Characterize material properties of HFR-HSC at ambient temperatures; v) Assess fire-induced spalling resistance and material properties of HFR-HSC at high-temperatures; vi) Quantify the overall sustainability of biomanufacturing HFR-HSC. Our work is expected to facilitate the value-added use of a discarded product leading to a reduction in the global carbon footprint.
