Types of concrete - Wikipedia

During the 1980s, Okamura and his Ph.D. student Kazamasa Ozawa at the University of Tokyo developed self-compacting concrete (SCC) which was cohesive, but flowable and took the shape of the formwork without use of any mechanical compaction. SCC is known as self-consolidating concrete in the United States. SCC is characterized by the following:

DIGITAL.CSIC: Behavior of High-Strength Polypropylene

We analyzed the behavior of the concrete at different temperatures (hot tests: 100°C, 300°C, 500°C and 700°C), cooled-down states (cold tests) and exposure times (6, 24, and 48 h). We also experimentally determined the thermogravimetric analysis, fracture behavior, compressive strength, Young¿s modulus, and tensile strength of concrete.

Experimental Study on the Stress Strain Behavior of Self

Tensile characteristics of concrete play an important role in structures. In this paper, the stress-strain behavior of self-compacting concrete modified by waste tire rubber (rubberized self-compacting concrete [RSCC]) under uniaxial tension is researched. Both monotonic and cyclic tests are conducted for RSCC with different rubber contents.
