Real-time measurement of the total amount of concrete poured to improve the durability of infrastructure structures.

In the infrastructure industry, the long-term durability of structures is extremely important. Particularly in public civil engineering structures, the quality of concrete greatly influences its lifespan. Managing the unit water content is essential to prevent cracking and deterioration, ensuring the durability of the structure. COARA can be installed in the piping section of concrete pump trucks to continuously measure the unit water content of fresh concrete in real-time. 【Usage Scenarios】 - Public civil engineering structures - 200-year homes - Infrastructure structures such as tunnels and bridges 【Benefits of Implementation】 - Real-time understanding of the unit water content for the total amount poured - Improved quality control of concrete - Assurance of long-term durability of structures - Utilization as traceability documentation

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.
