Concrete maturity monitor

Concrete maturity can be determined by profiling temperature within the hardening. This benefits the project in both quality and speed of construction as adequate 53 ACRI 400hydration can be determined and forms/shoring removed once target strength development is confirmed. The challenge is making sure that the temperature data is accurate and reliable as it is critical for quality assurance. As construction practices affect the ultimate outcome, the data is often demanded by structural engineers, quality control technician and owner representatives. Accurate temperature measurement must also be repeatable.

ACR SmartReader Plus 6 data logger devices suit both laboratory and field work as they are deployed without need for external power. The loggers are portable, multi-channel and self-powered using lithium battery guaranteed to last for 10 years. — ACR Systems Inc., Surrey, B.C., 800/663-7845 www.acrsystems.com53 ACRII 700
