Concrete Paving Quality Control Procedures: Water-Cementitious Materials Ratio (Microwave) Mobile App

Acceptance strength tests on hardened concrete are normally performed at least seven days after placement of the concrete. The microwave method can be used to obtain w/cm ratio results within hours, instead of waiting days for strength results. Monitoring the test results may provide an early flag of potentially low-strength concrete, allowing the contractor to adjust operations sooner than conventional strength testing might indicate. Concrete strength varies inversely with the amount of water in the mixture. In simplest terms, for a given cementitious content, less water leads to higher strength. Other factors, such as consolidation, curing, aggregate quality, air content, and aggregate shape, affect strength as well. For a given mixture with a constant amount of cement, the w/cm ratio has the greatest impact on strength. The Concrete Paving Quality Control Procedures: Water-Cementitious Materials Ratio (Microwave) mobile app covers: Purpose, Principle, Test Procedure, Test Method, Output and Construction Issues.

How It Works
I’m not a tech guy and I was able to pick this thing up in probably an hour, and actually start to build apps. I’ve done them over lunch when I’ve gotten frustrated with a process that didn’t exist in our company. So for non tech people who’ve got a problem, the support here is awesome and I’d recommend it to anybody, not just in our industry.
