High-durability concrete and preparation method thereof
The invention relates to the field of buildings, and particularly discloses high-durability concrete and a preparation method thereof.The concrete is prepared from cement, fly ash, steel slag, coarse aggregate, fine aggregate, silica fume, lithium slag, an additive, water and modified fibers; wherein the modified fiber is prepared by performing pressure impregnation on polylactic acid fiber in a low-boiling-point solvent, coating the polylactic acid fiber with an inner coating layer, mixing the polylactic acid fiber with sodium peroxide, and coating the mixture with an outer coating layer to form a porous outer wall coating layer; the preparation method comprises the following steps: S1, mixing and stirring the cement, the fly ash, the coarse aggregate, the fine aggregate, the steel slag, the lithium slag and the silica fume, and then adding the modified fibers to prepare a primary mixture; s2, mixing water and an additive, then adding the primary mixture prepared in the step S1, and mixing and stirring to obtain the concrete with better strength and durability.
本申请涉及建筑领域，具体公开了一种高耐久性混凝土及其制备方法，所述混凝土包括以下原料：水泥、粉煤灰、钢渣、粗骨料、细骨料、硅灰、锂渣、外加剂、水和改性纤维；其中改性纤维由聚乳酸纤维在低沸点溶剂中加压浸渍后经过内包衣层包覆，然后与过氧化钠混合后经过外包衣层包覆后形成多孔外包壁层制得；其制备方法包括以下步骤：S1、将水泥、粉煤灰、粗骨料、细骨料、钢渣、锂渣和硅灰混合搅拌，然后加入改性纤维制得初混物；S2、将水和外加剂混合，然后加入步骤S1中制得的初混物，混合搅拌制得，本申请具有制得强度和耐久性更好的混凝土。
