Test Application Plan
- Construction Method of Surface Coating / Modification for Concrete Structures -
The Purpose of Test Application:
In recent years, there have been advancements in surface coating and surface modification technology for concrete structures. And, based on the results attained from concrete coating material test that was done by JH Testing Laboratory last year, the purpose of this test application plan is to confirm the applicability and endurance of typical surface coating / modification material at actual construction sites.

Structural Format Simple Platter Mid Air Floorboard RC Continuous Mid Air Floorboard
PC Simple Mid Air Floorboard
PC Continuous Mid Air Floorboard
PC Continuous Box
Total Area 250 u 345.6 u
Deterioration Environment Salt Deterioration Environment Sea Level (m) 70m 600m
Salt Level at Reinforcing Bar (kg/u) 5.5 kg/u 0.30 kg/u
Weather Endurance Influence of UV Northeast side East-West Axis
Load Wear Out Influence of cars None None
Influence of Water from back side of structure Yes None
Current Situation of Structure No cracks Unknown
Comments High salt level at reinforcing bar and less cracks on surface of concrete indicates being in the initial stage of deterioration Low salt level indicates that the environment is less likely to cause any salt damages to the structure. Also, sea level of 600m indicates that salt composites are less likely to fly up and damage the structure
