Purpose: of this paper presents the experimental results of a study of strength and flexural behaviour of non-autoclaved foam-concrete beams reinforced with bamboo Design/methodology/approach: Six experimental samples of reinforced lightweight foamed concrete beams with hardened density D800 and D1200 with the same bamboo reinforcement were tested on lateral bending. Findings: A low level of anchoring of bamboo reinforcement in foam-concrete beams can provide their premature destruction. Research limitations/implications: Next experiments should be provided for improving the anchoring of bamboo reinforcement such as the bad adhesion between the bamboo and foam-concrete caused premature destruction of experimental samples. Practical implications: Replacement of steel reinforcement on the bamboo one in foamconcrete structures can be economical benefit. Originality/value: Increasing of experimental base leads to developing and creating new building standards in the nearest future.
