CEMENT STRENGTH VARIATIONS: DEFINING THE SOLUTION

As strength is one of cement's most important properties, major strength variations must be mitigated via control actions. Control actions can mask and obscure the deviations and their source. Locating the source of the problem is possible, though. This article describes a method in which individual production samples are divided by their fineness and the resulting values of strength per unit fineness are graphed versus time to determine exactly when strength deviations occurred and their magnitude. An example illustrates the method and demonstrates how the transformed data can be used to reveal the probable sources of the strength variations.
