NOVELTY - Self-repairing particle comprises 25-65 pts. wt. cement, 30-60 pts. wt. sand, 1-8 pts. wt. sodium silicate, 0.5-7 pts. wt. calcium sulfate, 1-6 pts. wt. sodium carbonate, 1-7 pts. wt. sodium bicarbonate, 1-6 pts. wt. magnesium chloride, 0.5-4 pts. wt. magnesium carbonate, 1-4 pts. wt. magnesium silicate and 0.01-0.1 pts. wt. graphene. USE - The particle is useful for protective sheet in building foundation pits or waterproofing projects (claimed). ADVANTAGE - The particle can be activated repeatedly when exposed to water, repairs the capillary channels in the concrete, improves the impermeability, and makes the concrete denser and waterproof. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) Self-repairing protective sheet, comprising the self-healing particles and a second self-adhesive modified asphalt waterproof layer, a base cloth layer, a first self-adhesive modified asphalt waterproof layer, and an isolation membrane layer. The thickness of the self-adhesive modified asphalt waterproof layer is 1-2mm, and the thickness of the tire base cloth layer is 0.5-1.2 mm. The size of self-healing particles is 1-5 mm. (2) Preparing the self-repairing protective sheet, comprising preparing the self-adhesive modified asphalt waterproof coiled material the prefabricated self-repairing are sprayed on the upper layer self-adhesive modified asphalt waterproof layer to fix the particles on the self-adhesive asphalt water proof layer to form theself-repairing sheet.
