A green composite material of calcium phosphate cement matrix with additions of car tire waste particles

The car tire waste have a tremendous adverse environmental impact in nature due to the large volumes generated worldwide, which requires multiple solutions that decrease as much as possible the tires disposed in landfills. Therefore, this research proposes to use part of the unused tire waste in a construction material, phosphate cement with ground rubber waste particles. For that, up to 12wt% of tire waste has been incorporated to cement. The samples characterization was conducted with scanning electron microscope; X?ray diffraction; compressive strength; thermal stability at 50 and 100°C; density; and Weibull statistics. Results show that this composite can be used as a building material therefore as an environmental solution for the rubber tire waste, mainly in applications requiring similar compressive strengths than concrete with ordinary Portland cement. Weibull statistics showed compression strength changing from 2.85 to 38.29 MPa, which is typical in construction materials and also it enables it to be used as building material. Density of samples was between 1.0 and 1.6 g/cm3, which open up applications for precast panels or other lightweight solutions.
