CA-3 concrete air content measuring instrument assists in quality control of large-scale municipal engineering

Customer background:

The client is a key municipal construction unit in a certain province, undertaking a new highway bridge project in the local area. They have high requirements for concrete quality, especially focusing on precise control of air content indicators to ensure the durability and frost resistance of the bridge.

Customer requirements:

The imported instruments originally used by the customer were cumbersome to operate, had high maintenance costs, and had long repair cycles, seriously affecting the construction progress. The customer is looking for a substitute product with high localization, easy operation, accurate measurement, and guaranteed after-sales service.

Solution:

The sales team recommended and demonstrated the CA-3 concrete air content analyzer on site, which has the following core advantages:

•The volume of the measuring cylinder is 7000ml, which meets the demand for large samples

•Wide range of gas content measurement (1%~10%), suitable for different concrete mix proportions

•Excellent pressure resistance, suitable for aggregates with a maximum particle size of ≤ 40mm

•The reading method is intuitive and concise, reducing operational errors

•Standard tools such as water injector, measuring cylinder, scraper, etc., easy to use

Implementation and feedback:

After a two-week trial, the customer expressed satisfaction with the performance of the CA-3 instrument. This equipment has provided accurate air content data multiple times during the testing process of bridge piers, columns, and deck concrete, helping the construction party adjust the mix proportion in a timely manner and avoid cracking hazards caused by excessive bubbles.

The customer highly praised the accuracy, repeatability, and stability of the instrument, and stated, "The equipment is simple and easy to use, and workers can get started after just one training session, greatly improving detection efficiency

Summary of Achievements:

•Successfully completed the bulk procurement of 15 devices

•Sign a 2-year after-sales maintenance agreement with the customer

•The equipment assistance project passed the municipal quality and safety sampling inspection
