High strength ultra toughness low shrinkage concrete
A-ecc is an ultra-high continuity cement-based composite with high strength, high ductility, high toughness and high durability through material design and adjustment, and can show strain hardening and multi-point cracking in tension
Typical application of traditional ECC —Meiyuan bridge, Japan
Pavement structure type
The ECC layer is pva-ecc；
PVA fiber volume content 2.0%；
Waterproof and crack resistant: the pavement layer is ECC layer (40mm) + wearing course

| It can realize early strength and fast hardening, the setting time is adjustable from 30min to 6h, and the strength of 3H / 28d is ≥ 0.5 | ||||
High toughness
Effectively solve the problem of pavement cracking caused by inconsistent stress and deformation caused by different thickness of pavement concrete
Low shrinkage
Effectively solve the problem of pavement cracking caused by inconsistent shrinkage between beam and pavement
Good adhesion
Effectively solve the pavement quality problems caused by falling off of reinforcement, extrusion of reinforcement mesh and ponding
Homogeneous and isotropic
Effectively solve the phenomenon of "bottom sinking" of reinforcement mesh
