[For Civil Engineering] COARA: Real-time measurement of fresh concrete unit water content.
Measure the total amount of concrete poured and optimize the quality and cost of the concrete.
In the civil engineering industry, ensuring the quality of concrete structures and reducing costs are important challenges. Particularly for public civil structures and those requiring long-term durability, it is essential to accurately manage the quality of concrete (water-to-cement ratio). An excess or deficiency in the water-to-cement ratio can lead to a decrease in concrete strength and cracking, which may result in repair costs and delays in construction schedules. COARA continuously measures the water-to-cement ratio of ready-mixed concrete in real-time by installing it in the piping section of concrete pump trucks, ensuring the quality of the total poured quantity. 【Usage Scenarios】 - Public civil engineering projects - 200-year housing - Tunnel construction - Dam construction 【Benefits of Implementation】 - Improvement in concrete quality - Optimization of material costs - Reduction in repair costs - Assurance of 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.
