BASED ON THEORETICAL MODEL RESEARCH PREDICTION MODEL OF FLY ASH CONCRETE’S CARBONATION DEPTH |

摘要 混凝土碳化深度理论模型理论基础性强,但工程应用性较差。影响粉煤灰混凝土碳化性能的因素主要有水胶比、水泥种类、单位水泥用量、CO2浓度、碳化时间和粉煤灰掺量等。根据粉煤灰混凝土的特点,基于理论模型建立了既有理论基础,又具有实际可操作性的粉煤灰混凝土碳化深度预测模型。 |

Abstract:
To the theoretical depth model of concrete carbonation, the theory foundation is strong, but engineering applicability is poor. The major factors influencing the properties of fly ash concrete carbonation are ratio of water to cementitious material ratio, cement type, unit cement dosage, CO2 concentration, carbonization time and dosage of fly ash, etc. According to the characteristics of the fly ash concrete, the fly ash concrete carbonation depth’s prediction model is set up, based on the theoretical model, the prediction model not only has sufficient theoretical foundation, but also has practical operability.
