“…Most researchers used one of three types of additives: organic additives, ash, and inorganic (non‐ash) additives. Examples of organic additives that have been used in clay bricks include several types of biomass and sludge, including wheat straw , sunflower seed cake , olive stone flour , sawdust , tobacco , grass , water hyacinth , sewage sludge , mushroom compost , paper pulp , pomace from the winery industry , and olive mill waste , among others . Examples of ashes used as additives in clay bricks include sugarcane bagasse ash , biochar , ash from incinerators and from coal‐fired power plants , rice husk ash , and wood ash .…”

The thermal and mechanical properties of fired clay bricks containing three different pore‐forming additives at comparable concentrations (~25 wt %) were investigated. The additives included three types: inorganic (vermiculite), organic (sawdust), and ash (wood ash). These additives have very different pore‐forming mechanisms during the firing process and leave very different residuals in the fired brick. Brick properties are affected by the brick forming process (e.g., the raw materials, forming, drying, and firing processes), and so there is wide variation in the effects of additives on brick properties in the published literature. Therefore, the objective of this effort was to compare selected properties of fired clay bricks with different types of additives, while keeping the brick forming process the same. In this study, the trends in bulk density, porosity, water absorption, compressive strength, and thermal conductivity with incorporation of additives in clay bricks support those that have been published. However, the thermal conductivity of the brick with 25 wt % wood ash was comparable to that for the brick without additives, despite having greater porosity and lower bulk density. This supports that both the pores formed during the firing process and the residuals of the additives significantly impact the brick properties. © 2019 American Institute of Chemical Engineers Environ Prog, 38: e13150, 2019

“…The thermal conductivity of the seven ULHS-ECCs in the current study is in the range of 0.38-0.46 w/mK (Figure 12), which is much lower than that of normal concrete (1.28-1.51 w/mK) and is comparable to the porous clay brick and porous masonry [29][30][31].…”

In this study, ultra-lightweight and high strength Engineered Cementitious Composites (ULHS-ECCs) are developed via lightweight filler incorporation and matrix composition tailoring. The mechanical, physical, and micromechanical properties of the resulting ULHS-ECCs are investigated and discussed. ULHS-ECCs with a density below 1300 kg/m3, a compressive strength beyond 60 MPa, a tensile strain capacity above 1%, and a thermal conductivity below 0.5 w/mK are developed. The inclusion of lightweight fillers and the variation in proportioning of the ternary binder can lead to a change in micromechanical properties, including the matrix fracture toughness and the fiber/matrix interface properties. As a result, the tensile strain-hardening performance of the ULHS-ECCs can be altered.

“…La pérdida de peso por sinterización es la pérdida de masa que experimentan los ladrillos de arcilla tras su cocción y se debe a la creación de porosidad en el sistema durante el proceso de secado y cocción, fundamentalmente por la deshidroxilación y carbonatación de los componentes de las arcillas (Bories et al, 2014). En el caso de los ecoladrillos se debe además a la formación porosa por la combustión y volatilización de los componentes orgánicos de las biomasas empleadas, tales como la celulosa, la hemicelulosa y la lignina (Sutcu et al, 2016;Eliche-Quesada et al, 2012a). Esta formación porosa produce la pérdida de peso, ya que el aire es más ligero que la matriz arcillosa y los agentes formadores de poros.…”

El ladrillo cerámico como material de construcción industrial contribuye negativamente al deterioro del medioambiente, tanto por el agotamiento de los recursos naturales como por la elevada cantidad de energía necesaria para su fabricación, que se traduce en emisiones de CO2. La incorporación de productos residuales o subproductos procedentes de diversos procesos industriales ha dado lugar a los denominados «ecoladrillos». En este trabajo de investigación se estudia el comportamiento de ladrillos cerámicos con la incorporación de diferentes biomasas residuales con la función de generar una red porosa que modiﬁque sus propiedades para adaptarlos a los requerimientos técnicos actuales. Para ello se han fabricado 19 tipos de ladrillos con la incorporación de 6 subproductos biomásicos: cascarilla de arroz (C), cáscara de almendra (CA), hueso de aceituna (HA), hoja de olivo (HO,) leña de olivo (LO) y poda de olivo (PO). Las biomasas se han incorporado a una arcilla convencional en tres proporciones en volumen (7,5 %, 15 % y 25 %), con tres tamaños de distribución de partícula (0/1 mm, 1/2 mm y 0/2 mm). Los resultados obtenidos muestran que el tamaño de partícula no ha condicionado el comportamiento físico y mecánico de los ecoladrillos, no así la proporción de biomasa, aunque en ningún caso se ha comprometido la normal funcionalidad de los mismos. Por el contrario, se ha observado una mejora considerable en la conductividad térmica de los ecoladrillos fabricados, fundamentalmente, con los menores porcentajes de reemplazo.
