Concrete Mixing Uniformity

 

The Datatrace DNAŽ Concrete Quality Control Test: A Patent-Pending, Rapid, Reliable, In-Situ Indicator of Homogeneity, Water Content, and Strength in Concrete

Abstract: This work reports a new, convenient, quality-control technique for rapidly and unequivocally establishing the homogeneity, water content, and indicative final compression strength of concrete, both in pre-poured (wet form) and post poured (dry form) states.

 Extremely tiny quantities of a range of unique Datatrace-DNAŽ  marker materials are incorporated within the components of concrete during its formulation. These markers impart the concrete with an invisible spectral signature that provides an accurate and reliable measure of its mixing homogeneity, water content, and likely final compression strength.

At any time after the addition of the markers, these key properties can be quickly and easily monitored using a small, custom-designed electronic reader. The interrogation process involves line-of-sight contact between the reader and the concrete, with each reading complete in seconds (see chart below).

This technique provides, for the first time, a quality control measure with which to rapidly and reliably establish the key physical properties of a batch of concrete before it is poured. As the Datatrace DNAŽ markers are extremely robust and durable; the invisible spectral signature remains intact within the concrete for at least 25 years after pouring.

As such, the Datatrace DNAŽ Concrete Quality Control test provides a ubiquitous and long-lasting measure of the quality of the concrete.
