For example, extremely hard materials such as sapphire, carbides, and some ceramics require diamond or boron carbide. The medium hard materials, which includes harder metals and some aluminas, can be lapped with silicon carbide. Aluminum oxide is widely used in the glass and silicon industry because of its softer cut and lower cost.
Influence Factors on the Properties of Ultrahigh
Ultrahigh-performance fiber-reinforced concrete (UHPFRC) is a new type of concrete with excellent performance and good appliion prospects. However, expensive heat curing or high-pressure curing was often adopted to ensure the sufficient compressive strength. This study focuses on improving the compressive strength and workability of UHPFRC by changing the composition materials and the
