Command Alkon managers secure patent on mixing process, strength predictability

Sources: Command Alkon, Birmingham, Ala.; CP staff

Command Alkon product design and programming veterans Bob Phare and Charlene Hohl have been awarded U.S. Patent No. 9,533,429 – System and Process for Mixing Concrete Having Desired Strength Characteristics. It covers methods for a) rapidly determining the predicted strength of concrete prior to pouring; and, b) creating and maintaining a database in which mix designs and their performance characteristics can be logged and updated as hardened concrete’s actual strength is measured. Functions based on the technology will be incorporated in future versions of the quality control platform, COMMANDqc.

Embedded device tracks concrete strength, temperature

Quadrel has extended its quality control and enterprise software platforms for concrete production with vOrb, billing it as an “Internet of Concrete” solution akin to Internet of Things devices. The slab- or structure-embedded sensor alerts users on real-time concrete strength, indicating appropriate point of formwork removal; floor slab humidity levels; mass concrete temperatures; and, cylinder maturity. With vOrb, Quadrel contends, owners can access project quality data, contractors can accelerate construction, and producers can upsell as a value-add for performance mixes. — Quadrel Inc., Pittsburgh, 888/833-5557;,
