粉煤灰-矿渣复合掺合料对海工砼耐久性的影响

Effect on the Durability of Marine Concrete With Multiple Blending Materials

混凝土构筑物在海水中受冰冻、风浪和水质等因素的作用 ,容易损伤而导致使用寿命缩短。本文对掺有粉煤灰和矿渣的混凝土的强度、抗渗性、人工海水中的氯离子扩散及钢筋锈蚀性能等进行了研究。结果表明 。

Concrete buildings in marine enviroment are subject to the acts of freezing, tiding and other factors, all of these factors make a lot of damages to concrete and decrease its service life. In this paper the following characteristics of the concrete with fly ash and slag are studied, those are strength, impermeability, chloride ion diffusion and rust of steel bar. The result shows that the concrete mixed with fly ash and slag is superior to that of ordinary concrete in marine evironment.
