Benefits of Engineered Cementitious Composite (ECC) in Concrete Construction

The objective of engineered cementitious composites is to develop a robust and flexible material that can be utilized in various purpose where fiber reinforced concrete can’t be used. It is the newest concept.

The formation of cementitious materials with high ductility is useful for structural applications. The engineered cementitious composites contain properties of high strength concrete having improved tensile strain capacity.

Definition of Engineered Cementitious Composite

The components of engineered cementitious composite are identical to fiber reinforced concrete along with cement, sand, water, fiber, and a few chemical additives. Contrasting to the fiber reinforced concrete, the engineered cementitious composites do not contain huge volume of fiber.

The method for blending engineered cementitious composites is equivalent to that utilized for the normal concrete. The engineered cementitious composites are cost-effective as less fiber is applied and they retain the desired characteristics of strength and ductility.

The main variance in the properties of engineered cementitious composite and fiber reinforced concrete is that as soon as the engineered cementitious composite is cracked strain is solidified whereas the fiber reinforced concrete does not demonstrate such a behavior.

In fiber reinforced concrete, the crack forms with the crack of the fibers because of that the bearing strength of the stress is reduced. Besides, the engineered cementitious composites contain a high fracture toughness that has similarity with aluminium alloys, and the damage tolerance is tremendously high.

Usage Of Engineered Cementitious Composite

Engineered cementitious composites are utilized in shear elements which are dependent on a cyclic loading, in the mechanical components of the beam and column coalition, and for general structural repairs.

These composites are generally applied in structures which contain a high energy absorption, along with dampers, steel element joints and for hybrid steel connections.

Beside, structural applications, these compounds can be utilized as a shielding layer for enhancing the corrosive resistance of structures. Other probable targets of engineered cementitious composites contain underground structures, highway pavements, and bridge decks.
