摘要
通过快速碳化试验,研究了抗压强度、水灰比、粉煤灰掺量、水泥用量、温度和湿度对混凝土碳化深度和碳化速率的影响规律。结合试验数据并通过现有模型对比分析,给出了各因素较为合理的影响系数表达式和建议取值。
Through rapid carbonation test,the laws of carbonation depth and carbonation rate of concrete influenced by com- pressive strength,water-cement ratio,fly ash content,amount of cement,temperature and relative humidity were studied. By combin- ing the experimental data and comparative analysis of existing models,more reasonable expressions of each influence coefficient as well as the corresponding suggested values were proposed.
