This process is part of coastal management that aims to defend the coast. It is a repeated process since it is unable to stop the physical forces causing the loss of sand, but merely mitigate their effects. Answer and Explanation: 1
movement of sand by erecting fences 1 to 1.5 m high to cause a buildup of sand, leading to the formation of an artificial dune. The mechanical explanation for this process is that the fence slows down the flow of air, and this slowing down causes the air to release its load at this point. Two types of artificial dune are distinguished, depending

Sand-fixation with vegetation is a key measure in controlling desertification and promoting ecological restoration of desert ecosystems (Li et al., 2014).In arid and semiarid environments, ecological processes (eg. aboveground net primary production) of sand-fixing vegetation have long been assumed to be a consequence of hydrological processes which …
The Tamil Nadu government intends to create a new artificial sand manufacturing and sales strategy. The M-sand policy's final draught was delivered to the government in January 2021 by the state's Public Works Department. The proposed strategy will encourage the use of artificial sand as a substitute for natural sand in building.
It can be explained by the relationship between strength and dilatancy proposed by Bolton [29]. When Q has a lower value, it inhibits dilatancy due to the soil experiencing crushing instead of sliding. A lower D R value suggests that the sandy soil is characterized as medium-dense sand, leading to a lower dilatancy angle compared to dense sand.
To avoid the sand fraction effect on the secondary compression and to unify this behaviour between the soils with and without sands, a four-phase frame (Fig. 9) of sand-clay mixtures is introduced in this study (Dixon et al., 1985, Lee et al., 1999, Wood and Kumar, 2000, Wang et al., 2013, Shi and Yin, 2017).
Artificial sand is one of the building sands, which refers to rock particles with a particle size of less than 4.75 mm and is made by artificial crushing and sieving after soil …
The increase of artificial islands and land expansions in the water in the last years is significant. Approximately, 33,700 km2 of land has been reclaimed in the last 30 years. ... To create the mortar, they were burning the shells to produce lime and mix it with sand, ash, water and broken shells (Thompson et al. 2020).
The AS17PB and ASQS bend-rupture stresses were 31.8 ± 2.5 and 18.5 ± 1.5 MPa, respectively. The artificial stone developed with Blast Furnace Dust waste (AS17PB) was 58% more resistant than the one with quartz sand ASQS, which can be explained by hematite's greater bend strength when compared to quartzite.
The term "artificial sand," sometimes known as "crushed sand" or "mechanical sand" (or "m sand"), describes granules of rocks, mining tailings, or industrial waste with a particle size of less than 4.75 mm. Mechanical crushing and sieving are used to process it. A better option than river sand may be artificial sand produced by ...
This paper deals with the efficacy of creating artificial carbonate sand from crushed chalk to model the natural carbonate sand. Direct drained shear using 100 mm shear box and compressibility tests using 150 mm Rowe cell have been performed on artificial carbonate sand in order to determine the shear stress-strain and compressibility characteristics of the artificial …

Table 1 shows an example of the composition of silica sand and artificial sand. The main component of natural silica sand is SiO 2, and its content is as high as about 90%.When crushed, it becomes fine powder and dust (SiO 2) is scattered to the atmosphere.If the capability of the dust collector is high, the dust is not scattered but is collected into the dust collector.
