通过混凝土配合比中粉煤灰对水泥的不同取代量,研究了掺加二级粉煤灰混凝土的抗碳化性能,结果表明:混凝土的抗碳化性能随着粉煤灰掺量的上升而下降;如果掺量控制在一定范围内,混凝土的抗碳化性能可满足工程要求;单位体积内水泥和粉煤灰总用量对混凝土的抗碳化性能有很大影响。
The results show that the carbonation resistance of concrete decreases with the increase of the content of fly ash. If the dosage is controlled within a certain range, the carbonation resistance of concrete can meet the engineering requirements; the total amount of cement and fly ash per unit volume has a great impact on the carbonation resistance of concrete.
