“…Thus, addition of lime to soil not only increases its strength but also reduces its plastic nature and increases its stiffness. Similar trends in stress strain curves can be seen in the investigations of earlier researchers (Kavak, Bilgen, & Faruk Capar, 2011;Muhmed & Wanatowski, 2013;Sharma, Phanikumar, & Rao, 2008;Yıldız & Soğancı, 2012). …”

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.

Estos tres contenidos de cal fueron modificados con varias cantidades de CD para estudiar su efecto sobre la resistencia del suelo estabilizado. Se realizaron pruebas de resistencia a la compresión no confinada (UCS) en las muestras de suelo estabilizado de dimensiones 38 mm x 76 mm a diferentes edades de curado. Las muestras de UCS gastadas se trituraron y se tamizaron para llevar a cabo los límites de Atterberg y las pruebas de hinchamiento libre seguidas por difracción de rayos X (XRD) y microscop...

“…Neki znanstvenici koristili su otpadni materijal za stabilizaciju tla, uključujući ostatke kamena plovučca [12], keramičku prašinu [13], cementnu prašinu [14], ostatke keramičkih pločica [15], pepeo rižinih ljuski [16], stakleni otpad [17] i ostalo. Istraživanja su pokazala da je kombinacija konvencionalnih stabilizatora poput vapna i cementa, zajedno s aditivima, najčešće industrijskim otpadom, dala bolje rezultate [18][19][20][21][22][23][24][25]. Ovaj rad bazira se na upotrebi industrijskog otpada fosfogipsa (PG) koji služi kao dodatak vapnu.…”

“…Recently, industrial wastes have also been widely adopted as chemical stabilizers in soil stabilization enabling their reutilization [7]. However, literature suggests that lime along with additives, usually industrial wastes, results in better stabilization of soil [8][9][10][11][12][13][14]. One such industrial waste is Phosphogypsum (PG) produced from fertilizer plants.…”

The study involved utilization of an industrial waste, Phosphogypsum (PG), as an additive to lime stabilization of an expansive soil. Three lime dosages, namely, initial consumption of lime (ICL), optimum lime content (OLC), and less than ICL (LICL), were identified for the soil under study for stabilizing the soil. Along with lime, varying doses of PG were added to the soil for stabilization. The effect of stabilization was studied by performing index tests, namely, liquid limit, plastic limit, shrinkage limit, and free swell test, on pulverized remains of failed unconfined compression test specimens. The samples were also subjected to a microstructural study by means of scanning electron microscope. Addition of PG to lime resulted in improvement in the plasticity and swell-shrink characteristics. The microstructural study revealed the formation of a dense compact mass of stabilized soil.
