To investigate the effects of internal shear fragmentation on dry granular flow, in this study a series of ring shear tests were performed on quartz sand samples under different normal stresses (100 kPa, 200 kPa, and 300 kPa), shear displacements (3 m, 5 m, 10m, 15 m, and 20 m), and shear rates (30 deg min−1, 60 deg min−1, and 90 deg min−1). Next, the grain …
Silicon (Si) is the second most chemical element in the earth's crust. Quartz is the most common form of silica, accounting for 12.6% of the earth's crust volume (Götze, 2009).And, quartz is mainly composed of silicon dioxide (SiO 2), which is widely used in both traditional basic industries and high-tech fields due to its stable physical and chemical properties (Haus, 2005, …
The monotonic and cyclic simple shear behavior of several loose skeletal calcareous sands is investigated and compared to that of common Nevada and Ottawa quartz sands in order to draw contrasts between these types of materials and to develop stiffness and modulus degradation curves for quasi-nonlinear ground response analysis. Mobilized frictional resistance and cyclic …
Iron is a major impurity in quartz sand and must be strictly removed in many applications. However, the iron removal rate in most of the conventional purification process is not high enough. In this study, a fast, low-energy consuming, environment-friendly and simple process for purifying quartz is demonstrated by a combination of microwave heating and ultrasound …

The paper presents a study of the influence of grain-size distribution curve on the small strain shear modulus Gmax of quartz sand with subangular grain shape. The results of 163 resonant column tests on 25 different grain-size distribution curves are presented. It is demonstrated for a constant void ratio that while Gmax is not influenced by variations in the …
