Abstract
This request is about a process for assembling recycled aggregates from construction and demolition waste, such as debris and waste generated within the construction industry, such as: bad mixtures of concrete, bricks, tiles, stones, plasters, ceramics; as well as residues from the cleaning of concrete mixers in pre-mixed plants which produce pavements, foundry slags, mortars and/or concrete. Likewise, it relates to the formulation of said aggregates and to construction products obtained through them.
Claims4
A procedure for obtaining aggregates from construction and demolition waste, wherein the procedure comprises the following steps:
- a. collecting construction and demolition waste;
- b. separating one or more materials that do not enter a recycling process, these materials can be metals, pieces of construction rods, paper, cardboard, expanded polystyrene (EPS), broken glass, wood and all solid waste unrelated to the construction activity;
- c. transporting the remains of concrete, stone, gravel, mortars and clay materials to the crusher for their subsequent crushing;
- d. sifting out the crushed material, through a vibrating or rotating screen, equipment that consists of several overlapping meshes that separate the recycled aggregates into different particle sizes;
- where the resulting recycled aggregates are:
- fine recycled aggregate (0-2.5 millimeters), coarse recycled aggregate (2.5-5 millimeters) and confectionery (5-9 millimeters);
- aggregates with a particle size greater than 9 millimeters will re-enter the crushing process (Step c).
- e. making a mix having 24% or 30% at least of fine recycled aggregate;
- 35% or 44% of coarse recycled aggregate;
- 13%, 16% or 21% of binder;
- and 2%, 5% or 13% of water;
- f. carrying the mix up to a vibro-compactor machine having a mold;
- and,
- g. curing and drying the product obtained in step f.
