development of concrete with seasand

Preliminary Study on the Development of Concrete with

Findings: The sea sand, as available, is inferior to conventional river sand but proper washing for two times make it feasible for making concrete. For M20 grade concrete, two times washed sea sand can be used as fine aggregate totally replacing river sand as the workability and strength characteristics reach within the limits of acceptable level.

Development of Concrete Made with Seawater and Un

The internal organizations of that concrete was denser compared with normal concrete, and it was clear that the water-tightness, early strength, and long-term strength of seawater and unwashed sea sand concrete were increased. Reinforced concrete structures that used a non-corrosive reinforcing bar were durable in the long term.

Chloride Analysis of Sea Sand for Making Concrete ...

2016-5-6  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.

2020-12-19  The color of the sea sand is light brown. The sea sand contains salts that attract moisture from the atmosphere and such absorption causes dampness, efflorescence and disintegration of work. The sea sand also retards the setting time of cement. Due to all such reasons, it is the general rule to avoid the use of sea sand for engineering purposes.
