Rheology of Disturbed Fresh Concrete III. The Modified Slump Cone Test
This third paper describes the development of a simple worksite test intended to evaluate the two Bingham characteristics. The principle is to measure the time taken for the upper surface of the concrete sample, placed in a slump cone, to slump by 10 cm. Details of the experimental setup and method are given and an analysis is performed of the results of the test on the 78 mixes in the program. Semi-empirical models are suggested for the shear threshold and the plastic viscosity. The test can be used to evaluate the viscosity of concretes whose slump is between 12 and 26 cm.
