摘要
Abstract
The neutralization of steel fiber reinforced self-compacting concrete under loads subjected to the simultaneous attack of carbonization,acid rain,acid rain and carbonization working together is investigated by laboratory test.The influence of stress level and steel fiber content on neutralization of steel fiber reinforced self-compacting concrete is analyzed.It is found that the bending tensile stress accelerated the neutralization.The higher the stress level,the more serious the concrete corrosion.In contrast,the bending compressive stress slows down the neutralization.The results indicate that the neutralization depth of steel fiber reinforced self-compacting concrete decreases as the steel fiber content increases in a certain range.From the test data,it can be concluded that the coupling effect of carbonization and acid rain working together on the neutralization of steel fiber reinforced self-compacting concrete is produced,but the stress level and the steel fiber content on coupling effect have no significant influence.关键词
