Table 2: Methodology.

Objective Description
Analysis of the current situation of the construction sector in Spain and Argentina Study on waste generation and its reusing possibilities
Study of the bibliography on current international research works that develop eco-efficient construction products and systems
Development of hypotheses Study of dosages to validate the product in Spain.
Contact with Spanish companies that produce similar construction products to obtain baseline tests values
Obtain the Spanish regulations for concrete blocks and bricks of low density to compare them with Argentine standards.
Obtain the limit values that this product type must comply with this product type in Spain according to different tests to which they must be submitted
Characterization of physical and mechanical properties Tests plan. Methodology carried out during laboratory work
Manufacture of moulds and test pieces. Error test type performed in the laboratory of the Higher Technical School of Building Engineering (ETSIE) of the University of Seville
Analysis of results and comparison with those obtained in Argentina
Study of new constructive solutions using these new materials Use proposals as a result of an experimental campaign according to the characteristics of nZEB construction products
