Engineered Cementitious Composite, or, bendable concrete, is a strong and flexible material that can be used in several applications. The material ingredients of engineered cementitious composite are similar to that of fiber reinforced concrete. Unlike the fiber reinforced concrete, the engineered cementitious composites do not include large volume of fiber. The engineered cementitious composites have a high fracture toughness. It has ability to self-seal the crack by getting wet. Water hydrates cement particles and helps the cement to forms many products to fill in the crack. This self-healing behavior not only seals the crack to prevent transport of fluids, but mechanical properties are regained.
The development of this engineered cementitious composite brings architecture and infrastructure industry to a new experience. However, the concept of self-healing material might also be applied to the water pipes around Bangkok, even better around the globe, to solve the problem or leaking pipes.
Pipes leakage not only causes a huge amount of water wasting overtime but also causes a country a fortune in order to inspect and repair water pipe across cities.
Small spot of leakage is the opportunity cost of water that can be used wisely and country economics.
