“…These clay silicates and clay aluminates bond or gel to the clay particles together to further strengthen the soil. This reaction is dependent on time in the fact that the longer a specimen is allowed to cure, the more the clay reacts with the lime and the higher the strength [1,14].…”

“…In addition, pozzolanic reactions occur later between the calcium ions and the silica and alumina of the clay minerals. This results in the formation of cementitious products such as calcium-silicate-hydrates (C-S-H), calcium-aluminate-hydrates (C-A-H) and calcium-aluminum-silicate-hydrates (C-A-S-H) that are also responsible for the strength increase [1,7,13,18,27].…”

“…Several researchers have worked on the studying the effects of lime on soil properties including strength and modulus (Bell, 1996;Garzón, Cano, O`Kelly, & Sánchez-Soto, 2016), mineralogy and microstructure (Aldaood, Bouasker, & Al-Mukhtar, 2014b;Rajasekaran, Murali, & Srinivasaraghavan, 1997;Rajasekaran & Rao, 1997), permeability and compressibility (Rajasekaran & Rao, 2002a, 2002b and swell control (Aldaood, Bouasker, & Al-Mukhtar, 2014a;Seco, Ramírez, Miqueleiz, & García, 2011).

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. El CD se obtuvo triturando y tamizando las baldosas cerámicas de desecho de los desechos de la construcción.

“…The results showed that the strain rate has an important effect on the shear band orientation and the relevant destruction mechanism of sand. The shear strength and deformation features of clayey soil under monotonic and cyclic loading conditions have been studied by several researchers [49][50][51][52][53]. Whitman and Healy [54] conducted triaxial tests on Ottawa sand, Fort Peck sand, and Camp Cooke sand; the test results indicate that there is a critical loading rate for the three types of sand.…”

In this study, to explore the feasibility of a compacted red clay as an engineered barrier in landfills, the viscoplastic property of remodeled unsaturated reticulate red clay was studied through a series of triaxial tests. According to the deviatoric stress–axial strain curves obtained through loading tests with varying strain rates and under different conditions, the viscoplastic parameter β of remodeled reticulate red clay was obtained. The effects of different matric suctions and net confining pressures on the viscoplasticity of unsaturated reticulate clay were analyzed. The test results showed that remodeled reticulate red clays with different degrees of saturation have similar viscoplastic properties, and their stress–strain curves are all isotach. The stiffness of unsaturated reticulate red clay increased with increasing confining pressure and matric suction. The relationship between β and the net confining pressure can be described using a linear equation. The β value of the specimens increased with increasing matric suction under a constant net confining pressure. A similar linear relationship was observed between β and the matric suction. These relationships are explained considering the loading rate effect mechanism.
