Demolition activity plays an important role in the total energy consumption of the construction industry in the European Union. The indiscriminate use of non-renewable raw materials, energy consumption, and unsustainable design has led to a redefinition of the criteria to ensure environmental protection. This article introduces an experimental plan that determines the viability of a new type of construction material, obtained from crushed brick waste, to be introduced into the construction market. The potential of crushed brick waste as a raw material in the production of building precast products, obtained by curing a geopolymeric blend at 60 °C for 3 days, has been exploited. Geopolymers represent an important alternative in reducing emissions and energy consumption, whilst, at the same time, achieving a considerable mechanical performance. The results obtained from this study show that the geopolymers produced from crushed brick were characterized by good properties in terms of open porosity, water absorption, mechanical strength, and surface resistance values when compared to building materials produced using traditional technologies.

Pozzolanic materials and their usage in concrete production are nowadays widely spread. Their application as additives is inherent especially for the purpose of high strength concrete. This article deals with evaluation and comparison of the influence of two different supplementary cementitious materials on the properties of high strength concrete: natural pozzolana (NP) and finely crushed brick (FCB). The studied characteristics are basic physical properties with connection to mechanical parameters, and next to this, characterization of water transport. In the scope of this study results revealed better pertinence of finely crushed brick, as the appropriate replacement of cement was found out to be up to 30%, whilst for natural pozzolana only 10% of cement substitution is favourable. The open porosity as the first indicator of both mechanical and water transport properties appeared to be lower in all studied mixtures with FCB than in the case of NP. With increasing ratio of the additive to cement there is significant worsening of mechanical and water transport parameters when NP is involved. The behaviour of mixtures with FCB is better even when high amount of cement is substituted.

Resumen Se analizan las características térmicas y de resistencias mecánicas de materiales y elementos constructivos elaborados con suelos naturales estabilizados. La metodología parte de la recopilación bibliográfica de fuentes primarias, secundarias e información de ensayos propios, sobre la densidad, la conductividad térmica y las resistencias a la compresión, a la flexión y al corte correspondientes al adobe, los bloques de tierra comprimida (BTC), la tapia y la quincha, según diferentes autores. Además, se consideraron los valores establecidos por normas argentinas IRAM referidas al acondicionamiento térmico de edificios. Se elaboraron comparaciones entre sí y con algunos materiales industrializados, tales como los bloques de hormigón, los ladrillos cerámicos huecos y los ladrillos cocidos macizos. A partir de este análisis, se concluyó que la revisión bibliográfica no es suficiente para obtener una estandarización de los valores de conductividad y transmitancia térmica de los materiales y los elementos constructivos naturales. Así mismo, a partir de las comparaciones de valores se pudo observar cómo se relacionan la densidad de los materiales y la de los morteros, según las distintas técnicas, con el comportamiento térmico y las resistencias mecánicas. Palabras clave: Adobe; arquitectura sostenible; bahareque; bloque de tierra comprimida-BTC; materiales vernáculos de construcción; propiedades térmicas; quincha; resistencia mecánica; tapial   Comparative analysis of the thermal aspects and mechanical resistances for materials and elements of earth construction Abstract The thermal characteristics and mechanical resistance of some materials and constructive elements elaborated with stabilized natural soils are analyzed. The methodology took into account the bibliographic compilation of primary and secondary sources and information from own tests, on density, thermal conductivity and resistance to compression, flexion and cutting, corresponding to adobe, BTC, tapia and wattle and daub, according to different authors. In addition, it was considered the values established by Argentine standards IRAM referring to the thermal conditioning of buildings. Comparisons were made with each other and with some industrialized materials such as concrete blocks, hollow ceramic bricks, and solid fired bricks. From this analysis, it was concluded that the literature review is not enough to obtain a standardization conductivity and thermal transmittance values of natural building materials and elements. Furthermore, from the comparisons of values it was possible to observe how the density of materials and mortars, according to the different techniques, are related to thermal behavior and mechanical resistance.
