Abstract:

Urbanization and land development in Asia, including Malaysia, have led to an increase in offshore sand mining activities, leading to significant environmental and social issues. Excessive sand extraction disrupts the ocean system equilibrium, necessitating sustainable management strategies. This study examined Malaysian offshore sand mining practices to recommend sustainable management approaches to be adopted. Using case studies involving interviews and document analysis, data were collected from 34 participants from six federal and state government departments, business owners, technical ag

Abstract:

Tailing sand is one of the residue minerals obtained after tin extraction. It contains silica in between 94% and 99.5% and available in abundance at the Kinta Valley, Perak State, Malaysia. Permeability is one of the important molding sand properties and considered much in the sand casting mold preparation. This molding sand property plays a vital role in the sand casting process and helps to remove the gases during the casting processing. In this research work, samples of tailing sands were gathered from four identified ex tin mines located at the Perak State, Malaysia. They were investigated

The still configurations differed based on inclusion of 2 cm depth of sea sand layer in the basin, a layer of black paint in the basin and use of a 50 W PV-DC heater. The study was conducted to increase the

Abstract:

Tin tailing sand is one of the residues from tin extraction. Tailing sand for sampling was taken from Batu Gajah, which was one of the active locations in tin mining in Malaysia. The silica content of tailing sand from Batu Gajah is between 95.9 to 98.9%. This research is to determine the effect of grain size by the increasing of water content on the permeability number. Grain size is a major determinant of mould and core permeability and surface finish of the casting. In this research involved the process of conducting the mechanical sieve grading to identify the grain size for this research.

The zircon powder from Zircon Minerals Malaysia is a pure premium grade zircon sand milled 1.5 µm that contain ZrSiO4, ZrO2, HfO2, SiO2, Al2O3, TiO2, and Fe2O3. The monoclinic zirconia powders were synthesized from the zircon sand of Zircon Minerals Malaysia, by caustic fusion method at calcination temperatures between 500 °C to 800 °C. The as-synthesized zirconia was characterized through X-Ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric and differential thermal analysis (TG-DTA), and X-Ray fluorescence (XRF) techniques. The XRD results show two monoclinic phases

Abstract Clay is exhibited as plastic and sticky when a large amount of water is added to it. A stabilisation trial was developed using mixes of clayey sand and chemical stabilisation for the soil. Clayey sand samples were prepared by mixing different sand-clay ratios (5S5C, 7S3C, 9S1C and 10S0C). Then, chemical stabilization was applied by adding Ca-based binding agent at different ratios of 0%, 2% and 4% of the total weight of the clayey sand samples. A series of Unconfined Compressive Strength (UCS) tests were performed on the clayey sand samples at four curing times (3, 7, 14 and 28 days).

Ultimate lateral resistance and lateral subgrade modulus within a pile group are known as the key parameters in the soil-pile interaction phenomenon. In this study, a series of experimental investigation was carried out on single and group pile subjected to monotonic lateral loadings. Experimental investigations were conducted on twelve model pile groups of configurations 1 × 2, 1 × 3, 2 × 2, 3 × 3, and 3 × 2 for embedded length-to-diameter ratiol/d= 32 into loose and dense sand, spacing from 3 to 6

Finite element method was used to generate initial static stress condition and run dynamic analyses of the cut slopes. Factor of safety was then calculated using limit equilibrium method. Both sand and clay were analyzed in this study. The results show that steep slopes with initial safety factor of 1.5 are capable to sustain earthquake magnitude of 0.25g due to high shear strength of the soil. However, slopes with friction angle less than 21º for sand and cohesion
