Field Testing Equipment and Testing Methods (0-5820-P1)

This product describes the field testing equipment and testing methods used in Project 0-5820. The objective of the project was to develop a dynamic shear rheometer (DSR)-based field laboratory test and equipment to predict potential cement-admixture incompatibilities through the direct measurement of cement paste rheology. The primary use of DSR is to measure viscous and elastic behavior of asphalt binders. The product describes the ways in which the DSR was modified in this project to measure the rheological properties of cement paste effectively. It also describes the test procedure developed using the modified DSR as the rheology measuring device along with a high-shear mixing procedure under differing temperature conditions.
