What is PHC Pile?
- What is PHC Pile?
-
Essential and Foundational building materials that transfer building’s load to ground. Acronym of Pretensioned spun High strength Concrete Piles, PHC Pile is high strength concrete
produced by Pretension which concretes made using spun has
over 78.5MPa(800kgf/㎠) compressive strength. 
- 2001 JIS(Japanese Industrial Standard) Certified for the first time in the industry
- In 1991, For the first time in Korea, SAMIL started PHC Pile research with Japan’s Nippon Hume through technical cooperation and was successful in commercializing from 1992 based on the high level manufacturing technology. Along with that, certified for KSF 4306 in 1992 and ISO 9001 in 1996 and in line with the global era, acquired JIS (Japanese Industrial Standard) in 2001 for the first time in the industry.
PHC Pile
Characteristics
-
High Loading Capacity
- Design strength of concrete is 78.5MPa(800kgf/㎠) which is greatly larger than conventional PC Pile’s design strength 49.1MPa(500kgf/㎠), Long-term allowable compressive stress is high about 19.6MPa(200kgf/㎠) compared to 12.3MPa(125kgf/㎠) of PC Pile that it has high bearing capacity. Therefore economical design is possible.
-
High resistance in Hitting
- Bond of Aggregates and cement paste is extremely strong through AUTO CLAVE curing that CONCRETE’s compressive strength is fairly high. This means it has high resistance to hitting, and thus economical due to high constructability, probability of distress during driving is low even with increased driving times that it could certainly reach the supporting layers.
-
Economical Design is possible
- Large design bearing capacity and great resistance on driving force and more over, AUTO CLAVE curing enables production of high strength Pile in a short time that it is greatly economical to freely change the length design specifically for the condition of the ground on the field construction without delay in construction.
-
Low Reduction of Drying Shrinkage
- According to the experiment result of spun specimen, AUTO CLAVE curing CONCRETE in compare to atmospheric steam curing CONCRETE has significantly low CREEP and Drying Shrinkage.
-
High Chemical Resistance
- Experiments were conducted to put a test piece in 5% solutions of hydrochronic acid, acetate, lactic acid, and etc. PHC Pile in comparison to PC Pile had outstanding results on acid resistnace. This is because cement harding material’s composition is close by AUTO CLAVE curing , Cement paste and aggregate has very strong attachment.
-
Large Bending Moment
- In comparing relations between bending moment and axial force PC and PHC Piles, as axial force(N) increase, you can know the characteristic that PHC Pile’s rupture bending moment is greater than that of PC.
