This research is a continuation of work presented in reference [Soni et al 2024] in which a number of specimens were prepared. Micromechanical effective stem properties were computed. Here, we conduct micro and macro stiffness analysis of hemp stem reinforced concrete specimens with a 0 and a 0/90/0 orientations and testing. Based upon micromechanical models of predicting effective properties of stems and laminates, we have used NDSANDS module and CLAP module of ASCA [Soni, 1994]. Effective properties of at least 4 specimens of hemp stem reinforced concrete composite specimens are measured for both a 0 and 0/90/0 of hemp stem volume elements and are calculated using constituent properties [Bhoopati and Suresh 2019]. A set of hemp stem reinforced concrete composite specimens, (Figure 1), are prepared [Soni et al 2024] and considered for conducting tests and relevant stiffness analysis.
Keywords - hemp, stem, concrete, composites, macromechanics.
