Principles in the Production of Self-Healing Concrete: A Short Review
Faculty of Engineering, Universiti Teknologi MARA, 40450 Selangor, Malaysia
ABSTRACT
Self-healing concrete is an example of concretes with unique properties. In general, concrete is one of the building materials that is always used in the construction industry. This material is a simple combination of cement, water and aggregate and is used to build various structures. This material is one of the most widely used and durable building materials that can be shaped into any shape due to its high flexibility, so it is a very suitable option not only for strengthening the structure but also for shaping it. After drying, concrete becomes a hard and durable body, but one of its disadvantages is cracking against various factors, which require time and money to repair, and this is not economically viable. The main reason for concrete cracking is its low resistance to tensile forces. When force is applied to it, the concrete deforms and cracks. Although these gaps may be very small and cannot be seen with the naked eye, they deepen over time and can lead to structural damage. Many efforts have been made to strengthen the concrete, but this material will be damaged after a few years, which will cause water and moisture to penetrate into the rebars used in it.
