Abstract
ABSTRACT 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.
