Efficient concrete composite admixture and preparation method thereof
The invention discloses an efficient concrete composite admixture and a preparation method thereof. The composite admixture is formed by mixing and storing the following components in percentage by weight: 10%-15% of silicate, 1%-5% of potassium ethyl silicate, 3%-5% of lignosulfonate, 0.5%-1.5% of sodium sulfate, 1%-3.5% of sodium aliphatate, 0.1%-0.8% of sodium hydroxide, 0.3%-1% of sodium hydrogen sulfate, 1%-6% of cellulose, 1%-2.5% of triethanolamine, 0.01%-0.2% of a defoaming agent, 0.01%-0.1% of a pH regulator and 60%-82% of water by processing equipment. The composite admixture obtained by reasonably configuring various raw materials is simple to produce and excellent in performance, can effectively improve the water-reducing rate after being used, can greatly improve the durability of concrete and enhance the compression resistance, tensile strength, bending resistance and shear strength of the concrete, so that the service life of the concrete is prolonged, the hardening degree, freezing resistance and cohesiveness of the concrete can be remarkably improved, the bleeding amount is reduced, the homogeneity is improved, the composite admixture has certain chemical erosion resistance, and is suitable for many fields.
本发明公开了一种高效混凝土复合外加剂及其制备方法，由以下组分按重量百分比组成：硅酸盐10％‑15％、乙基硅酸钾1％‑5％、木质磺酸盐3％‑5％、硫酸钠0.5％‑1.5％、脂肪酸钠1％‑3.5％、氢氧化钠0.1％‑0.8％、硫酸氢钠0.3％‑1％、纤维素1％‑6％、三乙醇胺1％‑2.5％、消泡剂0.01％‑0.2％、pH调节剂0.01％‑0.1％和水60％‑82％通过加工设备混合搅拌所得。本发明通过合理配置各种原料所得的复合外加剂，生产简单，性能优良，使用后能有效提高减水率，能够大大提高混凝土的耐久性，增强混凝土的抗压、抗拉、抗弯、抗剪强度，从而提高其使用寿命，能显著提高混凝土的硬化度、抗冻性和粘结性，能够降低泌水量，提高匀质性，且具有一定的抗化学侵蚀能力，适用于较多领域。
