Abstract

In this study, an economic ultra-high performance concrete (UHPC) fabrication process is proposed and the mechanical properties are investigated. In order to better promote it in engineering projects, finite element analysis is conducted on ultra-high performance concrete-normal concrete (UHPC-NC) composite slabs and a normal concrete (NC) slab. By comparing UHPC-NC composite slabs with NC slabs of the same size, the flexural properties are derived and guidance is given for the further optimization of UHPC-NC floor slabs, so that the ultra-high-performance concrete can be used reasonably and efficiently for the promotion of engineering applications.
