The invention provides high-strength self-healing concrete, the high-strength self-healing concrete is prepared from the following raw materials in parts by weight: 100-120 parts of
Portland cement, 30-50 parts of water, 10-20 parts of
carbon dioxide foaming agents, 20-30 parts of dispersing agents, 55-65 parts of aggregates, 20-30 parts of microbial composites, 20-30 parts of modified
fiber compound, 1-3 parts of
phenol antioxidants, 1-3 parts of octadecanoic acid and 4-8 parts of modified
piperylene petroleum resin, the high-strength self-healing concrete has the advantages that through specific proportions and a specific preparation method, fracture strength and
compressive strength are improved to a certain extent, the self-healing capability of the concrete is enhanced,
repair time ofthe concrete is prolonged, high durability and compactness are realized, and the strength reversion rate of the repaired concrete is high; in view of the embodiment and proportions, components of thehigh-strength self-healing concrete have synergistic effects, the fracture strength and the
compressive strength of the concrete are decreased obviously when some components are replaced, and the reversion rate is reduced obviously.
