Offshore Sand as a Fine Aggregate for Concrete Production. In China, where coastal areas are rich in sea sand, sea sands are already in wide use in local concrete construction due to convenience in mining and transportation, mature technology, and lower costs; the cost of sea sand is only 50-70 per cent of imported freshwater sand [4].
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
substitute for river sand as fine aggregate for concrete. Experimental results show that the washed sea sand is ideal for concrete and plastering activities. When compared with river sand concrete, 50 and replacement of sea sand with river sand in concrete gives lesser in compressive, split and flexural strength. 6. REFERENCE
Sea sand can be used in concrete when regular sand is not available. The main worry is about the durability related properties as the sea sand has large amount of salts adhered on the its surface.
Globally, concrete industry is using desalted sea sand as fine aggregate. The desalting process consumes huge quantities of fresh water and electricity, increasing the material cost.
30-11-2017· More than 90% of the world's dredged sea-sand has been used as a raw material in the construction industry, with over 45% of the dredged sea-sand being used as fine aggregate for concrete .

30-07-2018· This study is experiment the suitability to use beach/sea sand as a substitute for river sand as fine aggregate for concrete. Experimental results show that the washed sea sand is ideal for concrete and plastering activities. REFERENCE. National sand study for Sri Lanka, vols. 1 and 2.
Sea-sand seawater concrete incorporating recycled coarse aggregate is attractive. ... (FRP) can effectively solve the durability problem associated with the abundance of chloride ions in sea-sand seawater concrete (SSC). Such use of SSC also offers a good opportunity for the incorporation of recycled coarse aggregate (RCA) ...
Sea sand concrete is a kind of concrete in which mixed sea sand as fine aggregate, which is large-scale application in the coastal areas in recent years, especially in ningbo area.The sea sand solves the problem of river sand shortage, coupled with cheaper price, most of the ready-mixed concrete companies are willing to use desalted sea sand instead of river sand.
15-10-2019· Fine aggregate (sand) cement concrete using sea sand can reach 30 – 35 n/mm2 was replaced with sea sand by weight. the proportions of meeting requirements of concrete for construction of fine aggregate replaced ranged from 20% to at the highway, the coastal protection works and.
Fine aggregate (sand) cement concrete using sea sand can reach 30 – 35 N/mm2 was replaced with Sea sand by weight. The proportions of meeting requirements of concrete for construction of fine aggregate replaced ranged from 20% to at the highway, the coastal protection works and islands.
22-07-2020· Use of sea sand as fine aggregate in concrete making In China, where coastal areas are rich in sea sand, and are already in wide use in local concrete construction. The estuaries of the rivers, which flow into the sea, also have sand depositions that have to be dredged out of ports for keeping the area free for movement of the ships.
