“…As shown in Figure 3, the major crystalline phase was quartz (SiO 2 , PDFcard 331161), which was found in both waste materials. Other previously reported compounds in the mineralogy of ceramic materials [5,17] [23], was observed in the porcelain stoneware powder.…”

“…In the studies by Medina et al [4], up to 25.0% of natural coarse aggregates were replaced with ceramic sanitaryware wastes to obtain concrete for structural purposes. 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].…”

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.

“…However, one should pay particular attention to the fact that not all types of ceramics have the same technical properties, and this solution is not useful in all cases that might seem beneficial from the technical point of view. For example, the research findings presented in [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] indicate the potential for using red ceramics for the production of cement concretes. Further, although it has been proven that the substitute for traditional gravel aggregate in the form of broken bricks [1,3,6,9,12] has less favourable properties, there are several ecological benefits of new solutions.…”

Abstract. The article presents the results of research on primary recycling properties of ceramic aggregates conducted following the procedures outlined in WT-1 2014 Aggregates − Technical Requirements. The material for the tests was obtained from a company producing sanitary ceramic products. Damaged ceramic products, coming from the factory waste heaps, were transported to the laboratory and crushed. This enabled producing aggregate that was later subjected to tests carried out on the aggregates commonly used in the production of mineral-asphalt mixes applied in making road surfaces. The factors that were examined include the following: the flow rate of fine aggregates (angularity of fine aggregate), fine particles content -methylene blue test, light-weight impurities content, frost resistance, bulk density of grains as well as water absorption determined by pycnometric method. The test results showed that the properties of the recycled aggregates are similar to those included in traditional aggregates used for the production of mineral-asphalt mixes. On the basis of the conducted analyses, the waste ceramic aggregate was recommended for use.
