The invention discloses a durable concrete, which is prepared from the following raw materials in weight percentage: 20-40% epoxy resin, 20-30% curing agent component, 30-40% glass particles, 5-15% glass fiber, 2 ‑5% nano inorganic antibacterial agent, 2‑5% polyhexamethylene biguanide. The durable concrete prepared by the invention adopts nano-inorganic antibacterial agent and polyhexamethylene biguanide organic-inorganic composite bactericide, which can form a long-acting antibacterial and waterproof rigid interlinked film, effectively solving the problem of immobilization and slow release in the antibacterial agent loading technology , can be used in light-transmitting sidewalks and semi-transparent walls. It can achieve long-term high antibacterial performance under bright and dark conditions. It also has obvious waterproof performance, environmental protection performance and good weather resistance. It meets the standard concrete The compressive strength and light transmittance design requirements of the mix ratio are improved, while the compressive and durable performance of the concrete is improved, and the preparation process is simple and the cost is low. |
