The core design concept of UHPC originates from the precise control of material microstructure.

Unlike ordinary concrete, UHPC follows the principle of closest packing, optimizing the particle size distribution of different particle size components to minimize internal defects and porosity of the material.

Researchers usually remove coarse aggregates, limit the maximum particle size of fine aggregates, and introduce active mineral admixtures such as silica fume and ultrafine fly ash to exert their micro filling effect and volcanic ash activity, making the cementitious system denser.
