“…Ceramic wastes can also be employed as supplementary cementitious materials (Reig, Tashima, Soriano, Borrachero, Monzó et al, 2013). The utilization of ceramic waste along with cement in concrete and blocks is well documented (Halicka, Ogrodnik, & Zegardlo, 2013;Pacheco-Torgal & Jalali, 2010;Silva, De Brito, & Veiga, 2008;Tavakoli et al, 2013;Veera Reddy, 2010;Wattanasiriwech, Saiton, & Wattanasiriwech, 2009). The formulation and use of lime mortars with ceramic particles has, in the past, been a very common technique (Matias, Faria, & Torres, 2014b).…”

The use of micro ceramic dust (CD) as an additive to lime in soil stabilization has been analysed in this study. CD was obtained by crushing and sieving of waste ceramic tiles from construction debris. The initial consumption of lime (ICL) for soil modification was determined using Eades and Grim pH test. In order to study the effect of lime content on soil stabilization, three different lime contents (below ICL, ICL and above ICL) were used for stabilizing the soil. These three lime contents were amended with various amounts of CD to study its effect on the strength of the stabilized soil. Unconfined compression strength (UCS) tests were carried out on the stabilized soil specimens of dimensions 38mm x 76mm at different ages of curing. The spent UCS samples were crushed and sieved to carry out Atterberg limits and free swell tests followed by x-ray diffraction (XRD) and scanning electron microscopy (SEM) tests for determining changes in microstructure. The results indicated that the addition of CD resulted in a marginally negative influence on the early strength of the stabilized soil at three days of curing whereas it enhanced the delayed strength of the soil at 28 days of curing, gaining between 12-14% strength. The effect of CD on the plasticity and swell-shrink of lime stabilized soil indicated a further reduction in plasticity and swell-shrink nature. The mineralogy of the amended soil revealed the formation of CSH and CAH minerals responsible for strength gain. SEM images used to analyse the microstructure of the virgin and stabilized soil, indicated the formation of a dense and compact microstructure. Finally, it was concluded that CD can be adopted as an auxiliary additive to lime in stabilization of expansive soil with provision of sufficient curing and the delayed onset of early strength due to CD can be overcome by using higher lime content in stabilization.Key words: Expansive soil, lime stabilization, ceramic dust, strength, mineralogy, microstructure Resumen El uso de polvo de cerámica micro (CD) como un aditivo a la cal en la estabilización del suelo se ha analizado en este estudio.

“…Studies on ceramic waste recycling involve the use of ceramic electrical insulator and sanitary ware waste as coarse aggregates in concrete (Halicka et al, 2013;Medina et al, 2012;Senthamarai et al, 2011), the use of coarse and fine aggregates and ceramic powder obtained from crushed ceramic wastes in concrete (Pacheco-Torgal and Jalali, 2010), and the use of waste mud from ceramic tile production (containing both coarse and fine particles) for paving block manufacturing (Wattanasiriwech et al, 2009). In reported studies, the ceramic waste is crushed and or milled to obtain coarse aggregates, fine aggregates and ceramic powder.…”

“…However, studies on the reuse of ceramic polishing residues in cement-based materials are scarce [4][5][6]. The polishing residue, called PPR if coming from 'porcellanato' tiles or MPR if coming from 'monoporosa' tiles, is a common waste from the ceramic industry, being, usually, landfilled.…”

The sludge coming from the polishing process of ceramic tiles, particularly 'porcellanato' and 'monoporosa', results in a large amount of waste that requires disposal in controlled landfills. Consequently, the financial and environmental costs of landfilling are very high. However, the 'porcellanato' and 'monoporosa' polishing residues could be used as supplementary cementitious material (SCM) instead of being disposed or landfilled. Therefore, in this study, the synergistic effect of 'porcellanato' and 'monoporosa' polishing residues (MixPR) as supplementary cementitious materials was reported. The physical and chemical characteristics of MixPR were determined by laser diffraction (particle size), X ray fluorescence (chemical composition) and X ray diffraction (mineral composition). The variability of the characteristics of the studied MixPR was evaluated over a period of three months at the source. Mortar compositions were studied replacing the cement content by MixPR (0, 10, 20, 25, 30 and 40% mass fractions). The mortars were characterized by their consistency index (flowtable), compressive strength, pozzolanic activity index, thermal behavior (calorimetry) and autogenous shrinkage. As a result, the mortar compositions using MixPR maintain their plasticity and show a high rate of pozzolanic activity index, reaching 111%. The compressive strength at 120 days of curing was 41.5 MPa when using 25% MixPR, as compared to 40.0 MPa when no MixPR was used (0% addition). At early ages (28 days) the use of 25% MixPR reduces the compressive strength by 10-15% due to the slow nature of the pozzolanic activity caused by the residue. The results show an improvement of the efficiency index (given in kg m −3 MPa −1 ) when using MixPR due to the reduction on cement consumption by 30%, reducing therefore the CO 2 emissions.
