COARA for Construction: Measurement of Fresh Concrete Water Content
Continuous RI Concrete Moisture Meter "COARA"
Real-time measurement of the total amount of concrete poured to streamline the process.
In the construction industry, there is always a demand for shortening construction periods while ensuring quality. Particularly in concrete pouring, managing the unit water volume is crucial; if this is insufficient, it can lead to cracking and reduced strength, resulting in repairs and rework that may impact the construction schedule. COARA supports quality management by continuously measuring the unit water volume of ready-mixed concrete in real-time when installed in the piping section of concrete pump trucks. 【Usage Scenarios】 - High-rise building construction - Bridge construction - 200-year housing - Public civil engineering structures 【Benefits of Implementation】 - Thorough quality management through real-time data collection - Early detection of anomalies and prompt response - Improved maintenance management efficiency through ensured traceability

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.
