“…Therefore, the chemical reactions between SiO 2 and Ca(OH) 2 resulted in the formation of additional C-S-H gels in the ceramic mortar [20]. Through the development of additional C-S-H gels, the porosity reduced and consequently resulted in higher strength of mortar at longer curing periods [21].…”

Amongst the potential solutions to a cleaner environment is to minimize the solid waste generation. The application of solid wastes in sustainable construction has attracted much attention due to the potential properties and low cost. In this study, the potential use of waste ceramic as cement and a fine aggregate replacement was investigated. Two mortar mixes were made: one as control with OPC and natural sand, while in the other mix the OPC was replaced by ceramic powder by 40% and fine aggregates were replaced by fine ceramic particles by 100%. Microstructural analyses then assessed the effect of waste ceramic on the performance of mortar. The results show that ceramic powder together with fine ceramic particles reduced the workability of mortar. It has been found that mortar mix containing waste ceramic obtained higher compressive and tensile strengths. The drying shrinkage of ceramic mortar was also found to be lower than that of OPC mortar. The effects of ceramic wastes on the performance of mortar were detected to be more considerable at ultimate ages owing to the pozzolanic nature of ceramic powder. The study revealed that the waste ceramic powder and finer particles are potential to be used in a sustainable mortar by improving the mechanical and microstructural properties.

“…Regarding the specific application of ceramic waste as a pozzolan material to act as OPC for structural concrete, Table 1 presents main works on this subject. A wide variation in the type of waste and related composition are highlighted in these works [ 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 ].…”

“…Irassar et al [ 35 ] investigated an Argentinean industrial waste mostly of quartz, 51.3% SiO 2 , 20% Al 2 O 3 and 11.5% CaO and feldspar, anorthite and hematite. Pokorný et al [ 36 ] evaluated the pozzolanic potential of Spanish industrial ceramic block waste, which was characterized by an elevate content of gypsite, 37% SiO 2 , 14.3% Al 2 O 3 , 15.2% CaO and 17.9% SO 3 , in addition to microcline, albite and muscovite. With similar work as in [ 35 ], Vejmelková et al [ 37 ] used thermal insulation block waste.…”

“…Another important point regarding the results present in Table 1 is that the pozzolanic potential of the investigated ceramic waste [ 36 , 37 , 38 , 39 , 40 , 41 , 42 ] was indirectly related to the decrease in strength of the hardened concrete. As exceptions, in [ 34 , 35 ] the authors applied the Frattini test to evaluated the pozzolanic potential.…”

Ceramic-based wastes generated from different industrial activities have increasingly been reused as construction material incorporated into concrete. In general, these wastes just replace common concrete aggregates such as sand and gravel. In the present work, waste from clay brick industries composted of kaolinite minerals were for the first time evaluated for their potential to be reused as the pozzolan constituent of a cement for structural concrete. Initial standard testes revealed that the clay ceramic waste (CCW) displays high pozzolanicity. Concrete was then produced with 10 and 20 wt.% of CCW mixed with ordinary Portland cement (OPC) as its pozzolan constituent. Compression strength of these concretes and of pure OPC as a control sample were determined in standard tests after 14 and 28 days of curing. In addition, the corresponding density, water absorption, capillarity and percentage of voids were measured together with the evaluation of microstructural indices by scanning electron microscopy. The initial tests confirmed that the CCW is indeed an effective pozzolanic potential due to a chemical effect by reacting with CH to generate C–S–H. Moreover, the technological results proved that CCW might effectively replace the pozzolan cement constituent for structural concrete.

“…The use of CWP as partial replacement of cement attracted the attention of several researchers [6,[23][24][25][26][27][28][29][30][31][32][33][34][35]. The main conclusion from the studies was that CWP showed slow pozzolanic activity which was evidenced at late ages.…”

The global production of ceramic waste powder (CWP), which is produced during the final polishing process of ceramic tiles, exceeds 22 billion tons. The disposal of CWP in landfills will cause significant environmental problems (i.e., soil, air, and groundwater pollution). CWP is characterized by its chemical composition that is mainly composed of silica (SiO 2 ) and alumina (Al 2 O 3 ). Both minerals represent more than 80% of the CWP composition. CWP has potentials to be used as an ingredient to partially or entirely replacing Portland cement to make eco-friendly concretes. This chapter summarizes the effect of using CWP in making eco-friendly concretes, with a particular focus on using CWP as a partial cement replacement in conventional-vibrated concrete (CVC) and self-compacting concrete (SCC), and the production of zero-cement alkali-activated concrete (AAC).
