The invention discloses mosquito-repellent high-performance concrete and a preparation method thereof, the water cement ratio of the concrete is 0.23-0.3, and a cementing material is prepared from the following components in percentage by mass: 30-50% of Portland cement, 30-40% of fine aggregate, 5-10% of coarse aggregate, 8-12% of fly ash, 5-8% of silica fume, 0.5-3% of functional polypropylene fiber and 3-5% of an additive. According to the invention, the polypropylene fiber with a long-acting mosquito repelling function is dispersed into the concrete, so that the anti-cracking and anti-seepage performance and anti-abrasion performance of the concrete can be obviously improved, the toughness of the concrete is increased, and the service life of the concrete is prolonged; the mosquito-repellent incense also contains effective mosquito-repellent components, can keep a continuous mosquito-repellent function, and is lasting in effect and non-toxic.
本发明公开了一种驱蚊高性能混凝土及其制备方法，所述混凝土水灰比为0.23～0.3，胶凝材料以质量百分比计，由以下组分制成：30～50％硅酸盐水泥、30～40％细集料、5～10％粗集料、8～12％粉煤灰、5～8％硅灰、0.5～3％功能性聚丙烯纤维、3～5％外加剂；本发明通过将具有长效驱蚊功能的聚丙烯纤维分散至混凝土中，能够明显改善混凝土的防裂抗渗性能、抗冲磨性能，增加混凝土的韧性，提高混凝土的使用寿命；并且还含有有效驱蚊成分，能够保持持续的驱蚊功能，效果持久无毒害。
