【摘要】 研究了不同潮湿养护条件和矿物掺合料的掺入对自然养护1年的C30普通混凝土自然碳化深度、吸水速率以及抵抗盐冻剥蚀性能的影响。结果表明,粉煤灰与矿渣粉的掺入会使混凝土碳化深度提高,导致抗盐冻性能的降低;混凝土早期潮湿养护对混凝土的抗盐冻性能有显著影响。更多还原

【Abstract】 The influence of early moist curing conditions and mineral admixture on the depth of natural carbonation,water absorption and the resistance to salt scaling of C30 ordinary concrete after 1 year of natural curing were investigated. The results show that the incorporation of fly ash and slag powder will increase the carbonation depth of the concrete and lead to the deterioration of resistance to concrete salt scaling. The early curing of concrete has a significant effect on the resistance to salt scaling of concrete.更多还原
