  • Use of seasand and seawater in concrete construction

    Strong evidence exists that a combination of mineral admixtures for the concrete and reinforcement with fiber reinforced polymer (FRP) can effectively solve the durability problem associated with the abundance of chloride ions in seasand seawater concrete (SSC) Such use of SSC also offers a good opportunity for the incorporation of recycled30112017· The lack of river sand has led to the use of seasand and crushed stone fines in many countries, with the use of seasand in the UK being an example More than 90% of the world’s dredged seasand has been used as a raw material in the construction industry, with over 45% of the dredged seasand being used as fine aggregate for concrete Use of seasand and seawater in concrete constructionAfter the sea sand is desalinated, it can also be used as construction sand and gravel, but the salt and chloride ions of the sea sand must be cleaned With the progress of sea sand cleaning technology, the application range of sea sand will be wider Japan strictly stipulates the limit value of chloride ion content per cubic meter of concreteCan sea sand be used for concrete after washed | LZZG

  • What is the properties of Sea sand concrete?

    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 surface1 Sea sand tends to very fine and rounded, Smooth rounded particles would offer less resistance to rearrangement than angular or elongated particles with rough surfaces 2 In sea water, chloride is present which will cause corrosion of steel and iron which ultimately leads to reducing the carrying capacity of steel and iron, so that the structure built using this may not be sustainableWhy We Can’t Use Sea Sand In Building Construction18112014· because sea water contains some ingredients that may cause the concrete to be decreased in strength and may have cracks after drying , for example , salt sulfur etc Sea sand contains the salts which would result in much faster deterioration of the structuresWhy engineers shouldn't use sea sand in making cement
