Product Description

 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


Ultra high performance fiber reinforced


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


main performance index
Compressive strength: above 30MPa
Direct tensile strength: above 2.0MPa
Ultimate tensile strain: 5.2%
Shrinkage: ≥ 0.15%

outstanding problems
7

8
The compressive strength is low, causing crushing under local wheel pressure;
There is no coarse aggregate, and the drying shrinkage is large, reaching 1500me, which is much higher than that of ordinary concrete 400me, resulting in hidden danger of cracking;



A-ecc core technology
Special high performance admixture
Super dispersion, plastic protection, viscosity reduction and shrinkage reduction

Steel fiber + PVA fiber
Improve the tensile strength and the distribution of tensile cracks

Composite mineral additive
Shrinkage reduction, toughening and hydration heat reduction

Dense skeleton accumulation
Reasonable grading of coarse and fine aggregate; Product quality stability and uniformity control system

Ultra high performance fiber reinforced

Product features

1011



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
