Concrete maturity monitor accelerates forming schedules, satisfies inspectors

42 ACRI 400Concrete maturity can be determined by profiling temperature within the hardening. This benefits the project in both quality and speed of construction as adequate hydration 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, especially in the minds of engineers, quality control representatives and owner representatives who are responsible for finished slabs and structures.

Accurate temperature measurement in curing concrete 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., 800/663-784542 ACRII 600
