The invention relates to the field of building materials, and particularly discloses abrasion-resistant and corrosion-resistant concrete and a preparation method thereof. The abrasion-resistant and corrosion-resistant concrete comprises the following components: cement, fly ash, slag powder, an expanding agent, fine aggregate, coarse aggregate, water, an additive and modified quartzite. The preparation method of the modified quartzite comprises the following steps: crushing quartzite, mixing the crushed quartzite with an acid solution, and conducting washing and roasting to obtain porous quartzite; atomizing and depositing an wear-resistant and corrosion-resistant additive on the porous quartzite to obtain quartzite particles; and (3) mixing carbide slag and the quartzite particles, and keeping the temperature at 950-1000 DEG C for 2-3 hours to obtain modified quartzite. The wear-resistant and corrosion-resistant additive is prepared from the following components: coal gangue, composite fibers, rice hull ash, a silane coupling agent KH-550 and a water repellent agent. The abrasion-resistant and corrosion-resistant concrete has the advantages of being good in sea wave and sediment abrasion resistance and chloride ion erosion resistance, high in impermeability and excellent in durability when being used for ocean engineering infrastructure construction.
本申请涉及建筑材料领域，具体公开了一种抗冲磨耐腐蚀混凝土及其制备方法。抗冲磨耐腐蚀混凝土包括以下组分：水泥、粉煤灰、矿渣粉、膨胀剂、细骨料、粗骨料、水、外加剂、改性石英岩；改性石英岩的制备方法：石英岩粉碎，与酸溶液混合，洗涤、焙烧，得多孔石英岩；将抗磨耐腐助剂经雾化沉积在多孔石英岩上，得石英岩颗粒；（3）将电石渣和石英岩颗粒混合，950‑1000℃保温2‑3h，得改性石英岩；磨耐腐助剂包括以下组分：煤矸石、复合纤维、稻壳灰、硅烷偶联剂KH‑550、疏水剂。本申请的抗冲磨耐腐蚀混凝土具有用于海洋工程基础设施建设时，抗海浪、泥沙冲磨和抗氯离子侵蚀能力好，抗渗能力强，耐久性优异的优点。
