The material with the particle size distribution (Fig. 7(b)) and the composition analogical to the termite nest material was prepared from the mixture of sand and kaolin in order to evaluate material properties. The determination of dry bending strength (Fig. 19(a)) and crushing (compressive) strength were performed using 40×40×160 mm test pieces. The microphotogra‐ phy of fracture planes (Fig. 19(b)) shows the grains of sand surrounded by the clay phase like in the termite nest material.
