提高以水泥和粉煤灰为胶凝材料的混凝土块体材料碳化性能的探讨(一)

Discussion on the carbonization performance of fly ash concrete (Ⅰ)

首先就混凝土的碳化机理做了简要说明,进而讨论了粉煤灰品质和掺量对混凝土碳化性能的影响并对有关的试验研究做了简要介绍。分析了影响以水泥和粉煤灰为胶凝材料的混凝土块材碳化性能的因素,最后强调提高以水泥和粉煤灰为胶凝材料的混凝土块材碳化性能的关键要素:一是要保持混凝土具有一定的碱度;二是提高混凝土的密实性,降低孔隙率,阻止CO2向混凝土内部渗透。

The paper discusses the effect of fly ash amount added in concrete on the concrete carbonization performance, and describes the key factors of improving the concrete carbonization performance, the concrete must be of alkalinity and good density to prevent the CO2 from permeating into the concrete.
