“…In addition, it will also have a major effect on reducing manufacturing costs of concrete, since the cost of cement represents over 45 % of the cost of the concrete material. Several authors have already confirmed that powders of ceramic wastes have a pozzolanic reactivity [5][6][7]. However, research conducted to date are few and do not assess the performance of concrete durability which it is a key issue.…”

“…Some proposals promote the use of waste from the ceramic industry, which has already gone through a process at high temperature, particularly waste from roof tiles (10)(11)(12)(13)(14)(15), bricks (16)(17)(18)(19) and floors tiles (20) as pozzolan. It is worth classifying this waste in terms of its potential as active pozzolanic capability and Portland cement additions.…”

Demolition ceramic wastes (DCWs) were investigated in order to determine their potential use as supplementary cementitious materials in Portland Blended Cements (PBCs). For this purpose, three ceramic wastes were investigated. After characterization of the materials used, the effect of ceramic waste replacement (8, 24 and 40% by mass) was analyzed. Pozzolanic activity, hydration progress, workability and compressive strength were determined at 2, 7 and 28 days. The results showed that the ground wastes behave as filler at an early age, but as hydration progresses, the pozzolanic activity of ceramic waste contributes to the strength requirement. RESUMEN:Cementos Portland con adiciones: manejo de residuos cerámicos de demolición. Se estudiaron residuos cerámicos de demolición (DCWs) a fin de determinar su potencial uso como materiales cementicios suplementarios en cementos mezcla (PBC). Para este propósito, se investigaron tres residuos cerámicos. Luego de la caracterización de los materiales a utilizar, se analizó el efecto del reemplazo por residuos cerámico (8, 24 y 40% en peso). Se estudió la actividad puzolánica, el progreso de la hidratación, la trabajabilidad y la resistencia a compresión a 2, 7 y 28 días. Los resultados mostraron que los residuos molidos se comportaron como fillers a edades tempranas, pero con el progreso de la hidratación, la actividad puzolánica de los residuos cerámicos contribuye a los requerimientos de resistencia.

“…Similarly, Pacheco-Torgal and Jalali [5] observed not only a slight increase in water absorption and permeability when replacing traditional coarse aggregates with ceramic wastes, but also superior durability when traditional sand was replaced. Furthermore, several studies have confirmed the potential of ceramic wastes to produce pozzolanic cements [6][7][8][9]. Among them, Puertas et al [7] not only successfully used up to 35.0% of certain types of ceramic wastes as pozzolan admixtures, but also proved their suitability as raw materials for Portland cement clinker production.…”

Ceramic materials represent around 45% of construction and demolition waste, and originate not only from the building process, but also as rejected bricks and tiles from industry. Despite the fact that these wastes are mostly used as road sub-base or construction backfill materials, they can also be employed as supplementary cementitious materials, or even as raw material for alkali-activated binders. This research aimed to investigate the properties and microstructure of alkali-activated cement pastes and mortars produced from ceramic waste materials of various origins. Sodium hydroxide and sodium silicate were used to prepare the activating solution.The compressive strength of the developed mortars ranged between 22 and 41 MPa after 7 days of curing at 65ºC, depending on the sodium concentration in the solution and the water/binder ratio. These results demonstrate the possibility of using alkali-activated ceramic materials in building applications.
