“…The addition of ceramic bricks to concrete has even been regulated by the German standard DIN 4163: “Concrete with contrite bricks—specification of production and use” in 1951 [7]. The current research on the use of red ceramics in concrete is mainly focused on the ecological effect and also on the physical and mechanical properties of this ceramic waste concrete [6,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25].…”

“…Gonzalez et al [8] manufactured structural concrete using recycled brick aggregates and stated that it was possible to produce concrete characterized by medium strength using a high percentage of aggregates obtained from recycled brick. Gonzales et al [9] investigated the effect of ceramic aggregates on the properties of high-performance concrete and showed that concrete produced with up to 30% fine red ceramic aggregates achieved similar or improved mechanical and durability properties to those of conventional concrete with natural aggregates.…”

This paper presents the results of research aimed at finding the possible ways of disposing of ceramic waste material, focusing mainly on the possibility of using it as aggregates in concretes exposed to an aggressive chemical environment (municipal sewage). The research part presents the preparation method and investigation of waste ceramic aggregates (red, glazed and sanitary ceramic aggregates). A suitable ratio of coarse to fine aggregates was selected, and their density, absorptivity and crushing strength were examined. All examined aggregates were also subjected to SEM analysis. Red ceramic aggregate is characterized by a greater degree of crushing compared to glazed and sanitary ceramic aggregate, by 205.7% and 439.4%, respectively. Another part of the research was to compare the properties of concrete with traditional aggregate (gravel, basalt) and with ceramic waste aggregate. The tested parameters included consistency, apparent density, absorptivity, flexural and compressive strengths of concretes. The study proved that the absorptivity of recycled composites is higher than that of traditional composites by 20.8–24.7%. The concrete based on sanitary ceramic waste has the highest strength parameters. Its compressive strength is higher by 10.5% and flexural strength by 5.9% compared with the basalt aggregate concrete. The compressive strength of sanitary ceramics concrete is higher by 42% and by 59% compared with concrete based on glazed ceramic and red ceramic aggregate, respectively. The last part of the research was to examine the resistance of concrete to aggressive environment. The scope of the work included the preparation of the research environment in the form of solutions with an increased concentration of aggressive agents (hydronium, sulfate, magnesium, ammonium ions). Among the concretes with ceramic aggregate, the highest decrease in the compressive strength was demonstrated by the concrete based on red ceramics (128.2%), while the smallest was demonstrated by the concrete based on sanitary ceramics (aggregate from sanitary ceramics (15.4%). The mass loss at different time intervals and compressive strength loss of samples stored in solutions were tested. The smallest weight loss caused by aggressive environment attack was recorded in the concrete based on ceramic sanitary and glazed aggregate (20.2% and 34.5%, respectively, after 120 days of aggressive environment).

“…Regarding exclusively red ceramic waste, Cabral et al [9] noted that the leftovers of roof tiles, blocks and bricks accounted for nearly 30% of the total of solid waste generated in Brazilian cities. In grouts, this material shows good results in researches, depicting the potential of the material inherent to these cementitious matrices for González et al [10].…”

The lack of control regarding waste generation is a problem still faced by the construction industry, whereas its inputs could be used in the production of new cementitious composites, maintaining the quality, performance and sustainability of structures. This study developed grouts through the substitution of natural aggregate for residues of crushed ceramic bricks, evaluating its fresh state and mechanical properties. The samples displayed loss of workability and initial slump in fresh state, besides loss of compressive strength, elastic modulus, total water absorption and capillary water absorption in hardened state. In addition, composites with grog presented less consistency in fresh state when compared to the reference sample. The differences were even greater over time. As for the hardened state, the compressive strength of the samples was similaramong them at both ages, and all results remained above 14 MPa at 28 days, as required by ASTM C476, hence being characterized as structural grouts for masonry. For the elastic modulus test, the results were higher for samples with lower amounts of waste due to less internal voids and higher volume of natural aggregates. The substitution of natural aggregate for civil construction waste (CCW) in the mixtures increased void ratio and water absorption, while causing the lowest specific gravities of the research. Overall, the sample that presented the most satisfactory values was CCW 25%, showing that it is possible to obtain benefits from waste produced in factories and buildings, even for higher replacement levels, occasionally

“…There have been many studies published in which concrete including different recycled materials is used for structural elements, for instance, RCA [12][13][14][15][16][17][18], RMA [2,[19][20][21][22][23][24][25][26][27], glass waste [28][29][30][31], crumb rubber waste [32][33][34], ceramic and tile industry waste [35], marble waste [36,37], plastic waste [38], and concrete slurry waste [39,40]. The use of RA as a partial or full replacement of aggregate in structural concrete was examined for manufacturing precast prestressed beams [41], paving with precast concrete [23], paving blocks or hollow tiles [25], concrete masonry blocks for indoor applications [19,20], or concrete wall blocks for mortarless masonry [2]. The utilization of RA for reinforced concrete structural elements is limited due to the inferior durability properties of RAC [42,43].…”

Sustainable Masonry Made from Recycled Aggregates: LCA Case Study

For a sustainable building industry, reusable construction with a low demand for primary resources is needed. Moreover, if we want to reduce the amount of construction and demolition waste, construction with recycled aggregate should be considered. To investigate the environmental impacts of such concrete construction, life cycle assessment (LCA) was used to compare the following types of concrete construction: Reusable blocks with recycled brick aggregate, reusable blocks with recycled concrete, reusable blocks with natural aggregate, and regular concrete wall. Firstly, the properties of new concrete with recycled aggregate were measured, such as physical, mechanical, and thermal properties. Then, different constructions were designed and assessed using the method of Institute of Environmental Sciences (CML2001) and the method of National Institute for Public Health and the Environment (ReCiPe 2016) as characterization methods. Unsurprisingly, the regular concrete wall had a higher impact on most of the impact categories, e.g., 113 kg CO 2 eq. (in the first scenario, using CML2001). In accordance with the circular principles, the reusability of blocks and recycling of aggregate are the main factors that affect the environmental impact of the constructions. Thus, the global warming potential (GWP) of construction with reusable recycled concrete blocks was only 53 kg CO 2 eq. (in the second scenario). Moreover, we show differences in the results of CML2001 and ReCiPe 2016, e.g., in the Photochemical Oxidant Creation category.
