The durability of prefabricated large panel building in Beijing

The durable performance of the prefabricated panel building in Beijing was analyzed through the formatted questionnaire survey. Survey results showed that the majority of the respondent thought there was no or mild cracking, leakage, condensation & mould on the prefabricated concrete panel building. More than 75% percent of the respondents held a same above attitude. Which is much different from general opinion that the prefabricate panel building is a kind of structure with poor durability. From the three aspects of the panel building durability, more than 20% percent respondents had the idea that there was much serious and more serious leakage on the roof. So the water resist is one of the important factors to be thought in progress of construction industrialization.
