Flow Table Test
The flow table test (Tattersall 1991; Bartos 1992; Wong et al. 2000; Bartos, Sonebi, and Tamimi 2002) measures the horizontal […]
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.
Fill Box Test (Simulated Filling Test, Filling Capacity Box, Kajima Test)
The fill box test (EFNARC 2002; Bartos, Sonebi, and Tamimi 2002) measures the passing ability and segregation resistance of self-compacting concrete.

FHPCM
The Flow of High Performance Concrete Meter (FHPCM) is based on the design of the Tattersall two-point device (MKII) and
Delivery-Chute Torque Meter
The delivery-chute torque meter (US patent 4,332,158; Wong et al. 2000) is designed to measure the consistency of concrete as
Delivery-Chute Depth Meter
The delivery-chute depth meter (US patent 4,578,989; Wong et al. 2000) is similar to the delivery-chute torque meter in that
Cone Penetration Test
The cone penetration test (Sachan and Kameswara Rao 1998) was developed to be a superior test for measuring the workability
Confined Flow Test Methods
Only three confined flow tests methods for concrete are presented in this document. However, the use of confined flow in
Compaction Test
Like the compaction factor test, the compaction test (Bartos 1992; Bartos, Sonebi, and Tamimi 2002) expresses workability in terms of
Compaction Factor Test
The compaction factor test (Powers 1968; Neville 1981; Bartos 1992; Bartos, Sonebi, and Tamimi 2002) measures the degree of compaction
