Sand is a granular material composed of finely divided rock and mineral particles. Sand has various compositions but is defined by its grain size. Sand grains are smaller than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass.
Sea sand does not have high compressive strength, high tensile strength, so it cannot be used in construction activities. Sea sand contains salts which deteriorates the plastered surface and the slab surface and in the long run cause seepage in the building
Sea sand does not have high compressive strength, high tensile strength etc so it cannot be used in construction activities. In addition to this, the salt in sea sand tends to absorb moisture from atmosphere, bringing dampness.
The use of sea sand and seawater in concrete can provide sustainability to natural resources, while improving the mechanical properties of concrete. The corrosion of steel-reinforcement is inevitable with the use of sea sand seawater concrete.
