By 1988, the concept was developed and ready for the first real-scale tests.

The first paper on SCC was presented at the second East-Asia and Pacific Conference on Structural Engineering and Construction (EASEC-2) in 1989, followed by another presentation at an Energy Diversification Research Laboratories (CANMET)/American Concrete Institute (ACI) meeting in 1992.

They are of tremendous help in understanding SCC’s behavior.

A rheometer is a device that applies a range of shear rates and monitors the force needed to maintain these shear rates in a plastic material. A few concrete and mortar rheometers are available on the market and have been and are still used for measuring the yield stress, viscosity and other rheological characteristics of SCC.During his research, Okamura found that the main cause of the poor durability performances of Japanese concrete in structures was the inadequate consolidation of the concrete in the casting operations.
