This paper is part of an experimental series to investigate the potential use of ferrocement panels as a permanent form of reinforced concrete slabs with lightweight blocks infill. The ferrocement panels used are engineered with polyvinyl alcohol (PVA) fiber to have a strain hardening which can be characterized as high-performance fiber-reinforced cementitious composite (HPFRCC), called Engineered Ferrocement (EF). In the experimental work, ferrocement control panels and hybrid ferrocement panels were tested for strength capacity and hard strain behavior through flexure, toughness, and multitrack forming. The results showed that by using the ideal fiber/wire mesh content, the hybrid ferrocement panels act as a strain-hardening cementitious material, and successfully increasing the flexure strength compared to the control-group ferrocement. The initial investigation indicates that hybrid PVA fiber ferrocement in tensile zones can be successfully used as permanent form.
