摘要

超高性能混凝土(UHPC)蠕变行为的实验观察是有限的,现有的研究都是在包括纤维在内的材料设计上进行的。这限制了对胶凝材料潜在行为的理解,包括基本蠕变和干燥蠕变的相对贡献。在考虑两种不同样本量的情况下,对UHPC试样进行了为期一年的基础蠕变和干燥蠕变试验研究。结果表明,基性蠕变与干燥蠕变的幅度差异不大,表明基性蠕变是控制蠕变的机制。对现有的fib模型规范2010中的蠕变模型进行了校核和重新标定。

Basic and drying creep of ultra-high performance concrete
Experimental observations of the creep behaviour of ultra-high performance concrete (UHPC) are limited, with existing studies all performed on material designs including fibres. This limits the understanding of the underlying behaviour of the cementitious material, including the relative contributions of basic and drying creep. An experimental study of the basic and drying creep was performed on UHPC samples subjected to two different loads for the duration of a year, with two different sample sizes considered. It is demonstrated that there is little difference in magnitude between basic and drying creep, indicating that basic creep is the governing mechanism. The existing creep model in the fib model code 2010 is examined and recalibrated for UHPC.
