  • Publication number: 20240174566
    Abstract: Provided are a nano-titanium dioxide (NT)/biochar (BC) composite, and a preparation method and use thereof, which belong to the technical field of cement-based materials. NT is introduced into a porous structure of the micron-sized BC, which not only addresses the high aggregation of NT, but also reduces Ca(OH)2 size and crystal growth orientation through effects such as filling and nucleation brought by NT in the porous structure of BC. In this way, more C—S—H gels are generated to fill the pores, thereby improving an interfacial transition zone (ITZ), which enhances the mechanical properties such as compressive strength and flexural strength.
