Waterproof anti-crack concrete admixture and preparation method thereof
The invention discloses a waterproof anti-crack concrete admixture, which is prepared from the following ingredients in parts by mass: 10 to 15 parts of sodium gluconate, 3 to 5 parts of silica gel powder, 0.8 to 1.2 parts of rubber, 8 to 12 parts of rattan skin, 10 to 13 parts of water reducing agents, 1 to 1.2 parts of polyethylene sodium sulfonate, 0.4 to 0.7 part of methyl cellulose, 2 to 5 parts of antioxidants and 1 to 2 parts of surfactants. The components are stirred at a high speed to prepare the waterproof anti-crack concrete admixture. The silica gel powder and the rubber are added to increase the water resistance and hydrophobicity of the admixture, the prepared concrete admixture enables concrete to have better hydrophobicity in actual use, the grinding slurry of the rattan skin is added, the rattan has high toughness and elasticity, the rattan is ground into slurry to be mixed in the admixture to be used in cooperation with the concrete, and the water resistance and hydrophobicity of the admixture are improved. The cohesive force of the concrete is increased, and the problem that the concrete is easy to crack is avoided.
本发明公开了一种防水抗裂混凝土外加剂，按照质量份包括以下组分：葡萄糖酸钠10‑15份、硅胶粉3‑5份、橡胶0.8‑1.2份、藤条皮8‑12份、减水剂10‑13份、聚乙烯磺酸钠1‑1.2份、甲基纤维素0.4‑0.7份、抗氧化剂2‑5份、表面活性剂1‑2份；按照上述组份高速搅拌制备获得防水抗裂混凝土外加剂；本发明通过加入硅胶粉和橡胶来增加外加剂的抗水憎水性，使制备的混凝土外加剂在实际使用时使混凝土具备更好的疏水性，并增加了藤条皮的研磨浆料，藤条具有较强的韧性和弹性，研磨成浆混合在外加剂内配合混凝土使用，增加了混凝土的粘结力，避免了混凝土容易出现开裂的问题。
