Concrete Sand. Concrete sand is and aggregate sand usually composed of either gneiss, trap rock, limestone or granite. This specific type of sand is normally crushed at the quarry and then washed and screened for quality. This process will make sure that there are no large ...Salt Water Concrete—A Reality | Monolithic Dome Institute· It is common knowledge that using salt water, sea water or salty sand is not a possibility when building concrete structures. The problem with using anything salty doesn't lie with the concrete; the problem is with steel reinforcing. The minute steel reinforcing comes in contact with salt water, it begins to rust. As steel rusts, it expands and breaks up the surrounding concrete. This is not ...

Chloride Analysis of Sea Sand for Making Concrete ...

Usage of sea sand for concrete development is the possible alternative for river sand and avoids the excessive sand mining which may cause ecological and environmental problems. Sea sand is not used in concrete, since it contains chloride ions which can corrode steel. In order to avoid the corrosion, the salt content of the sea sand must be eliminated before being utilized in concrete.How can sea sand be used in concrete? - Quora· Sea sand comes from the disintegration of sea corals as a result of the action of waves. It generally has much lesser density compared to sand from other sources, therefore not ideal to be used in concrete. A good concrete mixture needs to have strong course and fine aggregates (sand) to meet the required strength. 664 viewsSea Water in or on Concrete| Concrete Construction Magazine· In general, good quality concrete is adequately resistant to the effects of sea water, salt water, salt and salt-bearing materials that come into contact with it externally.
