Abstract: The present study aims to produce workable bio-based concretes with consistence indexes around 265 ± 15 mm, free of pressing process with bio-aggregates such as bamboo particles, wood shavings and rice husk. To produce the concretes, a nominal water-to-cement ratio of 0.45, a cement amount of 687 kg/m3 and a volume fraction of the bio-aggregates of 50%, were used for all mixtures. Appropriate compensating water amounts and the use of adequate dosages of viscosity modifying agent (VMA) allowed obtaining bio-concretes of high workability without exudation and segregation. The fresh property used was the consistence index through the flow table test, while the hardened property determined was the compressive stress-strain behavior at 1, 7 and 28 days. The results showed workable and consistent mixtures, with mechanical properties that can allow industrial scale production of construction components
