Eco-Blocks have become a low-cost construction material and a valid recycling method to reduce waste disposal in regions where industrial recycling is not yet available. Design and create a prototype of an ecological block using recycled materials such as PET, Styrofoam and natural ocoxal fibers, to increase the resistance to axial compression. The methodology was quasi-experimental, descriptive. Two prototypes of ecoblocks were designed, containing the same amount of materials such as cement, gravel, sand, varying the volume of the PET, Styrofoam and ocoxal fibers. Prototype 1 had the highest resistance to axial compression, achieving a result of 41.2708 kgf/cm2 , prototype 2 achieved a resistance of 32.8125 kgf/cm2 .
