Solid waste generation of Hydraulic Concrete is a new polluting of the earth. The most produced material in the world is the Portland Cement (PC), but its disadvantage lies on its requiring fossil fuels, as well as the COx discharge to the atmosphere. Re-use of Hydraulic Concrete waste abates simultaneously a number of problems, as dumping of solid waste and COx compounds into the environment; affectation of quarry sand and gravel stones, as well as endemic flora and fauna living in them; storm-water runoff by the inability of strata to filter demolished concrete contained in landfills. The use of crushed aggregates coming from Hydraulic Concrete demolition is used to generate Recycled Concrete, a material that can abate costs, diminish pollution, reduce the cost of building, and protect quarries from unnecessary exploitation. Nonetheless, development of Recycled Concrete faces the challenge of finding optimal designs to achieve the highest mechanical performance under static and dynamic stresses, the need to produce concretes less susceptible to carbonation, and therefore, to corrosion of reinforcing steel that protect with the concrete core, aside from waterproof and dense concrete.
