in China? Huaxin Cement Co., Ltd. gave the answer. Recently, after passing the strict inspection of the State Inspection Group, the leading enterprise in the building materials industry announced that it had successfully developed the first ultra-high performance concrete product with compressive strength of more than 600 MPa in China, and had industrial scale production capacity.
This breakthrough not only marks Huaxin's leading position in the field of ultra-high performance concrete, but also provides unprecedented material support for key projects such as national defense engineering. Special engineering protective structures such as
national defense need to consider extreme conditions such as high strain rate, high-speed impact load and instantaneous high temperature, which have strict requirements for the strength of protective structural materials. As a new generation of cement-based composite material with ultra-high strength, high toughness and high durability, ultra-high performance concrete has attracted the attention of key project builders at home and abroad. However, limited by material, technology and other factors, the strength of the most widely used ultra-high performance concrete in the past is usually 120 ~ 160 MPa, which can only partially meet the material requirements of national defense engineering protection structures. Therefore, it is of great significance to develop mature preparation technology of ultra-high performance concrete with higher strength grade. Based on the theory of multi-source strength enhancement, the material research and development team
of Huaxin Company has successfully developed this ultra-high performance concrete with "steel-like" properties by breaking through the conventional preparation methods. In laboratory tests, it has shown amazing hardness and strength, and can even deform and crack high-quality steel in mutual extrusion with high-hardness steel materials.
In recent years, Huaxin insists on cultivating and developing new quality productivity, devotes itself to the research and development of ultra-high performance concrete, and establishes the brand of ultra-high performance concrete, Chaokelong ®. Huaxin Chaokelong New Building Material Technology (Huangshi) Co., Ltd. has been recognized as a national high-tech enterprise. After technical precipitation and tackling key problems, Huaxin has formed an overall solution for research and development, production, design and construction of ultra-high performance concrete materials, with completely independent intellectual property rights.
At present, Huaxin Super Kelong ® can strengthen different mechanical properties and improve construction technology according to the needs, so that the construction of projects in special environments is more efficient, economical and safe. It has been successfully applied to the construction of cross-sea bridges, large hydropower stations, environmental protection factories, airports and other key projects, contributing to the promotion of Chinese-style modernization.
