| Abstract: | The resistance to chloride ion permeability of PHC piles is studied for PHC piles manufactured with the production processes of ＂autoclave treatment＂ and ＂pressure steaming free process＂. The index to resist chloride ion penetration in PHC concrete is obtained. Meanwhile, the erosion of concrete of PHC piles in service by chloride ions in seawater is studied by in- vestigation and sampling so as to get the chlorine ion erosion curve of PHC piles in service and master the penetration law of chloride ions in concrete of PHC piles, showing significance for getting to know the durable conditions of PHC piles. |
