MICROCAPSULE FOR SELF-HEALING CONCRETE AND PREPARATION METHOD THEREOF, AND SELF-HEALING CONCRETE AND PREPARATION METHOD THEREOF
Disclosed are a microcapsule for self-healing concrete and a preparation method thereof, and a self-healing concrete and a preparation method thereof. The microcapsule comprises a core and a wall, the components of the core comprising a healing agent, microcrystalline cellulose and Tween 80, and a material of the wall being a high-molecular organic material sensitive to stress of cracks. The preparation method for the self-healing concrete comprises steps of: weighing appropriate amounts of cement, sand, water and the above microcapsules, with each cubic meter of concrete containing 0.05 to 0.08 cubic meter of the microcapsules; stirring the cement, sand and microcapsules until uniformly dispersed to obtain a mixture; and pouring the water into the mixture, and stirring uniformly.
