Adobes have been used in construction since the first civilizations in the world, and to adapt this product to modern requirements, it is necessary to improve their mechanic resistance and to reduce water absorption. This paper contributes to the better understanding of the stabilization mechanisms of adobes with “synthetic termite saliva” and Bambusa vulgaris vittata particles as reinforcement. The chemical composition, density and aspect ratio of the bamboo particles were determined. “Synthetic termite saliva” and bamboo particles improved physical properties of adobes, reducing linear shrinkage, water absorption, and the loss of mass in water. The agglomeration of the particles promoted by the “synthetic termite saliva” improved the packing of the soil particles, decreasing capillarity, and forming a more cohesive microstructure. The use of chemical stabilization and reinforcement with 6% of bamboo particles increased the compressive strength up to 90%. (C) 2015 Published by Elsevier Ltd.
