[For Bridges] COARA: Real-time measurement of fresh concrete unit water content
Measure the total amount of concrete poured to ensure the safety of the bridge.
In bridge construction, the quality of concrete is a crucial factor that influences the safety and durability of structures. In particular, managing the unit water content is essential to prevent cracking and deterioration, ensuring the long-term integrity of the structure. COARA continuously measures the unit water content of fresh concrete in real-time by installing it in the piping section of concrete pump trucks, guaranteeing the quality of the total poured quantity. This strengthens quality management in bridge construction and contributes to improved safety. 【Usage Scenarios】 - Bridge construction sites - Public civil engineering projects - Projects where quality management is emphasized 【Benefits of Implementation】 - Stabilization of concrete quality - Improvement of structural durability - Assurance of traceability - Accumulation of maintenance management data

Since our establishment, we have developed many measurement technologies that utilize various types of radiation emitted by radioisotopes, particularly gamma rays and neutron rays, in the construction field, specifically the RI method. The characteristics of the RI method are "non-destructive," "rapid," and "high precision." Currently, based on the development of unique measuring instruments that leverage these characteristics and the proposal of investigation methods, we focus on consulting that comprehensively addresses issues related to ground and soil construction by combining soil and geological surveys. Additionally, we also engage in the sale and rental of these RI instruments. Please feel free to contact us if you have any requests.
