AI Technical Summary
Existing hardening accelerators for mineral binders, particularly those used in prestressed and steel-reinforced concrete, are complex and expensive to produce, often contain harmful substances like nitrates, and require processes that are not suitable for certain applications.
A method involving grinding a mineral solid, such as limestone and cement, in a liquid medium to produce extremely fine particles that serve as effective setting and hardening accelerators, eliminating the need for complex chemical synthesis and reducing the use of harmful substances.
The process results in accelerators that significantly increase compressive strength in mineral binders within 4-8 hours, are cost-effective, and are suitable for various applications without the drawbacks of traditional accelerators, including improved compatibility with conventional accelerators and reduced impact on workability.
