Abstract: This paper presents so e experi ental progra s conducted in the Materials Testing
Laboratory of the School of Architecture of Madrid on the inclusion of recycling aterials and
industrial by-products in ortar and concrete for architectural uses.
The ai s of the research are:
· reusing waste aterials.
· reducing the production costs of concrete in ter s of natural resources, energy and
econo ical costs.
· Modifying the echanical and physical properties of ortar and concrete in the fresh and
hardened states.
· esigning architectural applications of the odified ortar and concrete, taking into
account production and casting aspects.
The first experi ental progra deals with the inclusion in concrete of fiber-shaped rubber
particles fro used truck tires. This new aterial, also called rubberized concrete, has shown a
very good behaviour when subjected to dyna ic loads. A reduction of stiffness and an increase
of da ping capacity have been achieved, aintaining structural strength.
In the second experi ental progra , a self-leveling ce ent ortar containing illed slate
fro quarrying wastes used as an ad ixture was obtained. This ad ixture acts as a binder in
conjunction with the ce ent, aintaining its stability even under water. The ortar can be use as
a self-leveling substrate layer for flooring purposes.
The third case presents a ce ent-based ortar odified with waste products fro recycling
paper industries. The ain properties of this aterial are low density and ther al insulation
capacity. The ortar co position is adequate for sprayed applications.
All the researching progra s described in the paper were developed in accordance with the
waste producing co panies and building aterial producers.
