Concrete Workability
Since the early 20th century, the concrete industry has recognized the need to monitor concrete workability to ensure that concrete can be properly placed and can achieve adequate hardened strength. A myriad of test procedures for determining workability have been developed for research, mix proportioning, and field use. The vast majority of these test methods have never found any use beyond one or two initial studies. With the exception of the widely used slump test, the few methods that have been studied extensively have generally failed to gain widespread acceptance. Even with the increase in knowledge of concrete rheology, the slump test remains the predominately used test method for measuring concrete workability.
Mini-Slump Test
The mini-slump test, which was originally developed by Kantro (1980) and later modified by Zhor and Bremner (1998), measures the
Mini-Flow Test
The mini-flow test (Zhor and Bremner 1998) is a variation of the mini-slump test described in the above subsection. The
