what is the hardness limit of domestic concrete? recently, after passing the strict inspection of the national inspection group, huaxin cement announced that it has successfully developed the first domestic ultra-high performance concrete product with a compressive strength of more than 600mpa (megapascals), and has the ability to produce it on an industrial scale. this breakthrough not only marks huaxin's leading position in the field of ultra-high performance concrete, but will also provide material support for the construction of key projects.

concrete strength is usually measured in megapascals. generally speaking, the compressive strength of ordinary concrete is between 20 and 60 megapascals. the compressive strength of ultra-high performance concrete is generally above 150 megapascals, and some can reach above 200 megapascals.

ultra-high performance concrete is widely used, including bridge engineering, marine engineering, special security and protection engineering, etc. these fields have high requirements for concrete strength, anti-permeability, corrosion resistance and wear resistance.

huaxin's material research and development team has successfully developed ultra-high performance concrete with "steel-like" properties. in laboratory tests, it has demonstrated amazing hardness and strength, and in the mutual compression with high-hardness steel materials, it causes high-quality steel to deform and even crack.

in recent years, huaxin has insisted on cultivating and developing new quality productivity and committed to the research and development of ultra-high performance concrete. its subsidiary huaxin chao kelong new building materials technology (huangshi) co., ltd. has been recognized as a national high-tech enterprise. after technical accumulation and research, huaxin has formed an overall solution for the research and development, production, design and construction of ultra-high performance concrete materials, with completely independent intellectual property rights.

at present, huaxin chao kelon can strengthen different mechanical properties and improve construction processes according to needs, making engineering construction in special environments more efficient, economical and safe. it has been successfully applied to the construction of many key projects such as cross-sea bridges, large hydropower stations, environmental protection factories, airports, etc., contributing huaxin's strength to promoting china's modernization.
