“…The minimum void ratio depends on inherent properties of the soil such as the fines content, grain size distribution, grain shapes and the method of deposition (Cho et al, 2006;Yilmaz et al, 2008). There is no applicable ASTM procedure for determining minimum void ratio over the entire range of fines content.…”

“…However, laboratory testing conducted by [18] shows that D50 = 0.6 mm to 0.43 mm also liquefy with additional factors such as particle shape and the fine content. Results from [34] shows there is no relationship can be concluded between CU and cyclic resistance, and also the CC and cyclic resistance. The results have been shown in agreement with [22], which conducted studies on Khazar coastal sand at different percentage of mixtures, that it is hard to find a relationship between CC or CU to cyclic resistance as liquefaction indicator.…”

“…(a) 15% of fines (b) 70% of fines Fig. 6 -(a) [34] shows some results published by past researchers from year 1968 to 1999 on the effects of particle size gradation on the liquefaction resistance. From those results, some researchers claim mean grain size (D50) of 1.0 mm to 0.1 mm causes decreasing in liquefaction resistance.…”

Sand is well understood as susceptible material to liquefy under seismic condition. In many cases of liquefaction, the loss of property and damages occurred due to the earthquake phenomenon are caused by sandy soils. Thus, many laboratory experiments and field tests on soil liquefaction engineering have been mandatorily focusing on the liquefaction resistance of sand-fine mixtures. The interaction between sand and fines particles appears to be well studied subject. However, there are some contradictory findings on some factors influencing liquefaction resistance in sand-fine mixtures. Therefore, this paper aim to present results and current findings from previous researchers which focused on sand-fine mixtures using various type of sand to interpret liquefaction resistance and its behaviour. In addition, microstructure test needs to be conducted for verification and analysis of the results on grading and particle sizes characteristics. It has been identified that recent findings on the particle size distribution and grading characteristics of sand in sand-fine mixtures are still contradicting. It has also been found that there are no study using different types of sand to reconstitute tropical sand-fine mixtures; and limited study focused on the coefficient uniformity, CU and coefficient of curvature, CC on liquefaction resistance relationship.

“…From Figure 1, [18] concluded that about 78 % liquefaction out of 155 incidents occur when the mean grain size, D 50 is lied between 0.113 mm to 0.338 mm. [17] show that there is no relationship can be concluded between the coefficient of uniformity, C U and coefficient of curvature, C C with the cyclic resistance. The results have been shown to be in agreement with [19].…”

“…Moist or wet tamping technique is the most popular technique applied for sample preparation as used by past researchers such as [26]; [27]; [28]; [29]. Through this technique, the homogeneous of the sample can be produced ( [17]; [25]; [30]). Due to that, moist tamping with 5 % moisture content was applied to each samples of sand matrix soils in this study.…”

Sand is known as the main material in land reclamation works to develop and widen an area. It is important for the Geotechnical Engineer to ensure the sand used can accommodate the burden imposed from the structures to be built on it. Previous researchers have conducted studies on the strength of sand, whether focusing on the sand itself or with the presence of fines. However, the study of sand grain size effects in sand mixtures in affecting sand behavior is extremely limited. The sizes and angularity of the sand particle are believed to contribute to the behavior of sand mixtures soil. Hence, the study to investigate the effect of sand grain size on sand mixtures in term of undrained strength is being carried out. The sand was sieved to coarse sand, medium sand and fine sand then each size was mixed with kaolin at 0 %, 20 % and 40 %. The undrained strength was obtained from triaxial test on undrained condition. As a result, it is found that the maximum deviator stress, qmax increases with the decrease of fines (kaolin) content. On the other hand, at the same fines content, increased of sand size leads to the increased of qmax, which means the increased of undrained shear strength. In addition, the angular shape of sand particle was thought to contribute to the high value of undrained shear strength for the sand mixtures.
