  1. The concrete used in testing bridge is monitored and some performance at definite age including compressive strength, splitting fensile strength, frost resistance, scaling frost resistance, chloride ion diffusion coefficient ( dcl - ), resistance of carbonization and pore structure by mercury porosimetry are tested. these performances are compared with that of concrete which designed by traditional method. the results show that mechanical properties of concrete designed by high durability concrete proportion and traditional method meet require ment at any age, however, frost resistance, scaling frost resistance, chloride ion diffusion coefficient ( dcl - ), resistance of carbonization and pore structure of the former are better than the latter, so high durability concrete is economic benefit

    對試驗橋用混凝土的質進行監控,並成型試件測齡期內的抗壓強度、劈裂強度與抗凍融、抗鹽凍、離子擴散系數( dcl - ) 、抗碳化等耐久性能指標及孔結構,並與傳統混凝土進行對比研究,結果表明:高耐久性混凝土及按傳統配合比設計的混凝土的力學性能均能滿足相應齡期的求,但前者的抗凍融性能、抗鹽凍性能、抗碳化性能、 dcl -和孔結構明顯優於後者,並具有明顯的社會經濟效益。
