Engineered cementitious composites concrete-ECC

Engineered cementitious composites concrete mortar has super-high toughness and energy absorption ability compared with normal concrete. The ECC and the normal one have the similar ranges of tensile (4-6MP) and compressive strengths (30-80MP), while they have distinct differences in tensile deformation behavior.

But the normal one will fail in a brittle manner once its tensile strength is reached. However, the ECC plate ,after firs cracking, the tensile load capacity continues to increase with strain-hardening behavior accompanied by multiple cracks along the plate.

Application

Reinforce the masonry structure

For the replacement of easy distinct concrete structure when earthquake

Repair the water architectures engineering

Have strain-hardening capacity when under loading tensile strength

The tensile strength can be 50-200 times of normal

After first crack, it still have good stain-hardening behavior

When in high temperature, the fiber in the concrete will be decomposed, and the steam will be released along the route by the remain of fiber to avoid the damage of concrete.
