混凝土的碳化国内外学者研究的较多,而对掺粉煤灰水泥石碳化的研究甚少,由于在混凝土中掺入粉煤灰后其碳化速度较普通混凝土快2~3倍,所以近年来国内外学者对掺粉煤灰混凝土的耐久性十分关注,它直接影响着钢筋的锈蚀和建筑物的寿命,因而各国从耐久性出发对粉煤灰的掺量作了限制。我们为制定西安地区粉煤灰掺量的限度,开展了人工快速碳化
There are many scholars at home and abroad who research on the carbonization of concrete. However, there is little research on the carbonization of fly ash-cemented cement. Because the carbonization rate of fly ash mixed with concrete is 2-3 times faster than that of ordinary concrete, it has been in recent years. Scholars at home and abroad are very concerned about the durability of fly ash concrete. It directly affects the corrosion of steel bars and the life span of buildings. Therefore, various countries have made restrictions on the amount of fly ash in terms of durability. In order to formulate limits for the amount of fly ash in Xi’an, we have carried out artificial rapid carbonization.
