Abstract
This investigation is sea-sand of Jeju island seashore enforce chemical analysis and basic a property of matter test(XRF, XRD) for used to building-aggregate to concrete a property of matter. I want to data which feature of sea-sand and apply construction-aggregate to each year survey particle size of sea-sand and salt-content to sand and washed sand of EEZ, using sea-sand concrete compressive strength of salt-content variation, shell-size and compressive strength of shell-size and variation after concrete.
I've surveyed physical·chemical characteristic of sea-sand and possibility about it can be construction aggregate. Through this experimental consideration, I've gotten these conclusions.

(1) It can be divided to three kind of sands which were located in Jeju seashore. One is silicate sand including FeO3, SiO2, Al2O3 another is carbonate sand including CaO, LOI and the other sand mixed with silicate and carbonate those are proofed as a chemical analysis. As a result of photographing XRD and SEM the most substance of silicate sand is Feldspar those particle is sharp, hole is small and carbonate sand is calcite and particle is round shaped, developed an opening.

(2) Specific gravity of ocean sand follows in the picking area. It shows a difference, concrete fine aggregate's general specific gravity is inside standard(2.5~2.8) mostly, granularity size is minuteness but, Case of Sang-mo sand. It compares in the different area, The size of the particle appeared highly.

(3) The result of compressive strength for use construction aggregate which made from sand, Sang-mo sand's compressive strength is higher than standard strength and I-ho sand's strength is similar to standard strength.
And the sand of four area(Pyo-sun, Guem-newng, Hwa-soon, Sam-yang) is lower than standard strength. In this case it is good that use a mixture which consist of river sand and rubble.

(4) A result of a strength test a size of shell in ocean's sand hasn't an effected on intensity.

(5) Chlorination is included at sea-sand reinforcement as early stage strength, because of make cement hydration. It use much of chlorination, on the contrary that make deterioration strength.
