Foam concrete has recently become a key construction material in terms of meeting thespecial needs of modern engineering applications such as thermal insulation, absorption ofstatic and dynamic loads. In this study, the effect of polypropylene fiber content and variousuni- and tri-axial compression loads on the toughness response of polypropylene fiberreinforcedfoam concrete was investigated. Up to a certain strain level (0.1 mm/mm), theultimate compression stress of specimens under uni- and tri-axial loading increased fromabout 1 MPa to 16 MPa with the increased target densities of foam concrete. There was astrain-hardening capability of low-density foam concrete while the specimens failed by strainsofteningin the high-density series. The optimum fiber amounts were found to be 3.9%,4.6%, and 6.4% for low, medium, and high target densities of foam concrete, respectively. Atlow-density series, the bubbles were observed to be relatively bigger and mostly merged witheach other. A reduction in foam content (vice versa, increasing target density of mixture) andthe presence of fiber resulted in smaller pore size and a more homogenous distribution ofthem in the matrix. In conclusion, the desired pore structure and efficient bridging of fibers inthe matrix allowed the production of favorable foam concrete with higher toughness.
