Brazilian agriculture has been transformed, with large agribusiness structures, better use of space and better use of available resources, and thus the rural workers have preferred to live close to the workplace, which are usually agricultural small villages. These locations require simple homes, fast built and inexpensive, such as modular buildings, made with prefabricated panels, reducing the assembly time on ready foundations, with significant reduction of remains. As this typology still needs investigations, this work was to develop and evaluate vertical (walls) and horizontal (ceiling) panels using mortar and pet plastic bottles. The results led to a modular measure of 1.05 m, and building measure of 1.04 m wide by 2.75 m high by 0.15 m thick. The modular panels was defined with female system on the side edges and upper, allowing joints on-line, l, t or cross, as well as the joint between vertical panels and slab. The form for the panels were made of wood, 6 cm thick, with half diameter pvc pipe diameter of 7.5 cm fixed on the sides and upper face of the panel to shape the female type fitting. The panels were armed with a metal cage with steel stirrups of ca-60 4.2 mm arranged in two directions, each 20 cm in longitudinal and 25 cm transversal way. Inside the metal cage were inserted eight columns of pet bottles and, lastly, the assembly was encased in wire netting. The surroundings of window and door panels were reinforced with 4 ca-60 8.0 mm steel bars in the longitudinal direction and with 4.2 mm stirrups every 15 cm. The mortar had weight trace of 1.0: 2.0 and a factor w/c = 0.45. In the compression test, the panels presented linear deformation, with deflections in a security range, thus far away from a possible breakage. In the hard body impact test, the panel surface was adequate, showing great performance. In the vertical compression test, based on prisms, made the calculation, it was concluded that the panel was suitable for use on walls of houses up to two floors. In the bending test of the slab panel with up to 8 kn of load, it was concluded that it can be used even for slab with public access. In the shear test of the slab panel, as the load was higher than that recommended for public access, the panel was approved to be used as a ceiling or floor. The masonry panels had its cost about 2.5 times smaller than the conventional masonry. Finally, the proposed modular system can be recommended both as wall and as slabs.
