Method and non-reinforced concrete blocks to build masonry arch bridges This technology offers a solution for bridges and passageway construction that is innovative in terms of material used and building method. Precast concrete products for bridges and passageways are currently available in the market, but are composed of reinforced concrete and have a beam structure that is mostly resistant to tensile strength. The structure currently developed is an arch masonry structure, essentially resistant to compressive strength, and using non-reinforced concrete as key material. The advantages over existing solutions include a fast and straightforward building method, reduced structural maintenance, increased durability and resistance to wear, and ability to include construction waste materials in construction of blocks. Environmental gains result from non-inclusion of steel and non-compulsory use of high quality concrete. Economic gains, up to 50%, result from reduced material costs and shortened construction time. This solution finds application in the construction of small and medium-scale bridges, underpasses, rivers and drainage water. It can also be integrated with other processes essential to arch bridges, such as walls, floors, railings and guardrails, and others.
