High-strength concrete and production process thereof
The invention relates to the technical field of concrete products, and discloses high-strength concrete, and each part of the high-strength concrete comprises the following raw materials: 3-3.4 kg of cement and 1-1.4 L of water. 3 to 3.2 kg of fine sand, and 0.015 to 0.02 kg of a water repellent agent; 0.015 to 0.02 kg of a surface treating agent; the hydrophobing agent comprises fluorosilane and boric acid, and the surface treating agent comprises methyl tert-butyl ether and nano silicon dioxide. The high-strength concrete disclosed by the invention has the following advantages and effects of excellent corrosion resistance, high strength, wide application range and low shrinkage ratio. The prefabricated part prepared from the high-strength concrete has the advantages that the drying shrinkage and carbonization shrinkage ratio of the prefabricated part is reduced, the corrosion resistance is high, the strength is high, and the compression resistance and shock resistance are realized.
本发明涉及混凝土制品技术领域，公开了一种高强度混凝土，每份高强度混凝土的原料及配合比如下：水泥3‑3.4kg、水1‑1.4L；细砂3‑3.2kg、疏水剂0.015‑0.02kg；表面处理剂0.015‑0.02kg；疏水剂包括氟硅烷、硼酸，表面处理剂包括甲基叔丁基醚、纳米二氧化硅。本发明具有以下优点和效果：本发明的高强度混凝土，具有优异的耐腐蚀性能、高强度，使用范围广，同时还具备低收缩比。该高强度混凝土制备的预制件，且减少预制件干燥收缩和碳化收缩比，耐腐蚀性能强、强度高，具有抗压抗震的能力。
