Abstract:
On the thesis that workability cannot be expressed by a single numerical value, several new test methods have been devised. A test was developed for harshness (which measures the relative smoothness of an oversanded mix, compared to an undersanded mix), for segregation (which measures the separation of mortar when the concrete is jolted). for shear resistance (which measures the force required to shear the concrete) and for adhesion or stickiness(which measures the tensile strenqth of the concrete).
