“…Ceramic wastes mainly originate from the construction industry. 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 (Reig, Tashima, Soriano, Borrachero, Monzó, et al, 2013). The global production of ceramic tiles is around 8500 million square meters (Tavakoli, Heidari, & Karimian, 2013).…”

“…The specific gravity of ceramic wastes has been reported in the range of 2.27 to 2.82 by various investigators (Kamala & Rao, 2012;Sabat, 2012;Sekar, Ganesan, & Nampoothiri, 2011;Tavakoli et al, 2013;Veera Reddy, 2010). 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).…”

“…This indicates that the addition of CD to the stabilization process enables better progress of the pozzolanic reactions resulting in the destruction of crystal structure of minerals and hence, reflecting as reduced intensity of peaks in diffraction tests. Literature suggests that the major composition of CD is silica and alumina (Halicka et al, 2013;Pacheco-Torgal & Jalali, 2010;Reig, Tashima, Soriano, Borrachero, Monzo, et al, 2013;Tavakoli et al, 2013). CD being a known artificial pozzolan, these components reacts with calcium from lime to result in the formation of CSH and CAH.…”

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.

“…interesting characteristic of this material is the use of different raw materials in its formulation [6], such as industrial [7], agricultural [8] and civil construction [9] wastes. When compared to an OPC concrete a geopolymeric concrete has an energy consumption 45.8% lower, and it emits about 72% less carbon dioxide to the environment [10].…”

In addition to several positive aspects in technical properties, geopolymeric binders have considerable advantages in the environmental point of view, with lower energy consumption and lower CO 2 emission. In this study, it was conducted an overview about the utilized materials by some Brazilian researchers in geopolymers production, and also an experiment employing two types of wastes (red ceramic waste and rice husk ash). The compressive strength of the resulting material developed very fast, reaching a value of 11 MPa after one day. The microstructure was evaluated by scanning electron microscopy, revealing a compact microstructure and the presence of starting materials from the red ceramic waste that not completely reacted. The results indicated the feasibility of producing geopolymeric material without using commercial sodium silicate and cured at room temperature, showing an option for building materials production with lower environmental impacts. Keywords: geopolymer, alternative materials, sustainability, building materials. Resumo Além de vários aspectos positivos nas propriedades técnicas, aglomerantes geopoliméricos têm consideráveis vantagens do ponto de vista ambiental, com menor consumo de energia e menor emissão de CO 2 .

Abstract. Blends of Tungsten mining waste mud (TMWM) and brick waste powder (BP) with different dosages were used as precursors for the study of a new binder obtained by alkali-activation. The synthesis was obtained at 60ºC curing during the first 24 hours and at 20°C during the remaining period. A combination of sodium hydroxide (SH) and sodium silicate (SS) solutions was used with SS/SH weight ratio equal 1.5. The solid precursors/liquid activators weight ratio equal to 4. And the modules SiO 2 /Na 2 O increase with the increasing of BP dosages 5.21 and 5.59 for dosages 10% and 50%, respectively. Mineralogical characterisation of raw materials was carried out by X-ray diffraction (XRD). The effect of the dosage of BP on the compressive strength and pore size distribution of the new binder was investigated from 24 hours up to 28 days. The pore size distribution was obtained mercury intrusion porosimetry (MIP). The increase in the dosages of BP, between 10 to 50%, was followed by an increase in compressive strength, from 25 to 59 MPa, for all the tested ages. The binder matrix become more dense and compact with the gradually increase of BP dosages, as found out by MIP.
