Low-alkali, high-strength, anti-crack, anti-freezing and cold-resistant concrete suitable for plateau regions and preparation method thereof
The invention relates to the field of building materials, in particular to low-alkali, high-strength, anti-crack, anti-freezing and cold-resistant concrete suitable for plateau areas and a preparation method of the low-alkali, high-strength, anti-crack and anti-freezing and cold-resistant concrete. Comprising 140 to 180 parts of low-alkali reinforced Portland cement, 275 to 360 parts of coarse aggregate, 450 to 580 parts of fine aggregate, 40 to 60 parts of silica powder, 15 to 35 parts of lignin fiber, 1.8 to 3.6 parts of a superplasticizer and 100 parts of water. The concrete suitable for the plateau area is prepared by taking the low-alkali reinforced Portland cement as a main material, and compared with traditional low-alkali cement, the low-alkali reinforced Portland cement prepared by the preparation method disclosed by the invention is applied to the concrete, so that the strength is higher, the crack resistance is stronger, and the cold resistance and freezing resistance are better.
本发明涉及涉及建筑材料领域，具体涉及一种适用高原地区的低碱高强度抗裂抗冻耐寒的混凝土及其制备方法，混凝土按照重量份数计算，包括：140‑180份低碱增强硅酸盐水泥、275‑360份粗骨料、450‑580份细骨料、40‑60份硅微粉、15‑35份木质素纤维、1.8‑3.6份高效减水剂和100份水。本发明制备了一种适用高原地区的混凝土，采用低碱增强硅酸盐水泥作为主料制备得到，相比较于传统的低碱水泥，本发明制备的低碱增强硅酸盐水泥应用于混凝土内，不仅强度更高，而且抗裂性更强，耐寒抗冻性表现也更好。
