Ultra High Performance Concrete (UHPC)

Ultra-high performance concrete (UHPC), based on a solid theoretical foundation, replaces coarse aggregates with fine aggregates such as quartz sand, adds mineral admixtures rich in volcanic ash activity such as fly ash and blast furnace slag, incorporates short-cut fine fibers and high-efficiency water reducers, minimizes internal pores and microcracks, and controls the water-binder ratio. Under high-temperature steam curing conditions, its compressive strength is not less than 150 MPa, and its flexural strength can reach up to 40 MPa, resulting in a new type of cement-based composite material with good toughness and excellent durability.

During the grouting process, no other admixtures or admixtures shall be added to the cement-based grouting material, otherwise it is easy to cause product quality problems.
