解釋
冰凍剝落-
Abstract : the paper analyses and compares the current test methods of deicer - frost in different countries. on the basis of the study of influence on deicer - frost scaling of concrete, the test method of deicer - frost was further improved, and an easier preparing method of samples for deicer - frost and a quantitative evaluating method of frost - resistance were put forward
文摘:在分析、比較不同國家現行的鹽凍試驗方法，在研究影響混凝土除冰鹽剝蝕因素的基礎上，對鹽凍試驗方法進行改進，提出更簡易的鹽凍試件制備方法和抗鹽凍性能的量化評價方法。 -
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量進行監控，並成型試件測量所需齡期內的抗壓強度、劈裂強度與抗凍融、抗鹽凍、氯離子擴散系數（ 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要求，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。
