APPLICATION OF UHPC ULTRA-HIGH PERFORMANCE CONCRETE IN PRECAST Π-SHAPED STEEL COMPOSITE BEAMS
In the 1990 s,Hunan University started UHPC ultra-high performance concrete test,which made us preliminarily realize that UHPC ultra-high performance concrete has better toughness and durability performance than conventional concrete.Taking the construction of The first Contract Section of Hunan Changyi Expressway Expansion Project as an opportunity,UPHC ultra-high performance concrete has been put into practice in the structural joints of π-type steel composite beams,aiming to bring more creative space for future bridge construction.
