Engineered Cementitious Composite (ECC) is a material developed by Victor C.Li of the University of Michigan. Its greatest feature is strain hardening under uniaxial tensile stress and a maximum tensile strain of 8% due to the formation of multiple, dense multi-cracks . It is an extremely tough and ductile material behavior. ECC is based on the design principles of micro-mechanics and fracture mechanics, and it is possible to predict the material behavior and to bidirectionally design. Examples of applications that utilize these characteristics include seismic energy absorbing devices, repair / reinforcement materials (section repair or symptom), and steel coating materials.

Since Slurry Infiltrated Fiber Concrete (SIFCON) is manufactured by DRLankard in 1984 with the steel fiber pre-arranged in the mold and permeated into the cement slurry, it is also possible to achieve a fiber volume up to 20% . The compressive strength of a large amount of fibers is 210 MPa, and the compression / reinforcement structure, repair / reinforcement material, precast structure, and the like can be mentioned. SIMCON (Slurry Infiltrated Mat Concrete) uses fiber mat instead of steel fiber.

Ductal is an inorganic composite material born from the concept of Reactive Powder Concrete (RPC). RPC is a material using reactive powder and developed by P.Richard in 1994 as a new concept called ultrahigh strength + toughness which incorporates metal fiber into a cement matrix based on the theory of high density filling. Its characteristics are super high strength (compression 240MPa, flexure 45MPa), high durability (freezing and thaw resistance index 100), fluidity (flow 250mm) and applicable examples are foot bridge, thin wall lightweight soundproof panel and anchor plate for revetment wall.
