Research on properties and durability of desalinated sea
Fig. 1 shows that with the increase of sea sand content, the water absorption rate of sea sand mortar is gradually increasing. When the admixture fly ash Oil spills into the oceans cause irreparable damage to marine life and harms the coastal population of the affected areas. The main measures to be taken in response to an oil spill are to reduce the impact on marine life, prevent oil from reaching the shore through its recovery, and accelerate the degradation of unrecovered oil.

Exploring the properties of sea sand in sea sand–seawater
The particle size distribution was measured. The short-term mechanical properties of sea sand–seawater concrete were compared with conventional concrete. The concrete samples were cured in natural marine conditions and atmospheric conditions and tested at 7 and 28 days. Sea sand–seawater concrete had a high early compressive The use of sea sand and seawater in concrete can provide sustainability to natural resources, while improving the mechanical properties of concrete.

Catalytic ozonation for water and wastewater treatment
Ozonation for water treatment has gradually gained interest throughout the world. By 1940, about 119 drinking water treatment plants all over the world used ozone for water treatment, and by 1977, the numbers increased to at least 1039 (Rice et al., 1981).Although disinfection was the predominant early application, as a powerful oxidant, The results showed that the use of sea sand as a substitute for fine aggregate showed an average compressive strength in 7 days of 18.86 MPa, an average compressive strength of 14 days of 25.52(PDF) Analysis Of Use Sea Sand as A Fine Aggregate

Use of sea sand as fine aggregate in concrete making
Concrete is a mixture of cement, coarse aggregates, fine aggregates or sand and water. The approximate ratios of these components are as below: Based on the ratios and the anticipated cement consumption in the country, the expected requirement of sand will be about 500-550Mt in the next few years or so. Traditionally, river sand has been theTo study the bond performance between FRP bars and sea sand coral concrete (SSCC), 72 specimens of direct Pull-out were designed, and relevant tests were carried out to explore the effects of fibre types, bar diameters, bond lengths and SSCC strength grades.Experimental investigation on the bond performance of sea sand

Seawater-based bio-cementation of natural sea sand via
The sand column was prepared by packing the dry sea sand into a sterile 300 ml polyvinyl chloride (PVC) syringe with a diameter of 5 cm. For each sand column, 380 g of sea sand was added to the syringe and compacted via vibration until a height of 12.5 cm was reached, at which point the sand column’s density was ∼ 1.54 g/cm 3.One layer The seawater desalination industry in China has been expanding rapidly in recent decades. Per the cumulative completed desalination capacity exhibited in Fig. 1, the desalination capacity in China expanded remarkably in the annual rate of 35%–64% since 2005, and has been >1 million m 3 /d since 2016 [ 3, 4, 9 ].Seawater desalination technology and engineering in China: A
