High-strength high-performance concrete admixture and preparation method thereof
The invention relates to the technical field of concrete admixtures, and discloses a high-strength high-performance concrete admixture which is prepared from the following raw materials in percentage by weight: 50-60% of a non-polar solvent, 10-15% of water-soluble calcium salt, 3-5% of an emulsifier, 0.5-1% of a co-stabilizer, 8-11% of tetraethyl silicate, 0.1-0.2% of ammonia water and 10-28% of water. Meanwhile, the invention discloses a preparation method of the high-strength high-performance concrete admixture, and the preparation method comprises the following steps: firstly, mixing and stirring a mixed and prepared solution and a non-polar solution added with the emulsifier and the co-stabilizer in a water bath under the condition of 25-40 DEG C, and carrying out pre-emulsification treatment by virtue of an ultrasonic emulsification instrument, subjecting an obtained emulsified solution to heating demulsification treatment, so that when the prepared admixture is added into concrete, the admixture can be more uniformly mixed with the concrete, the strength of the concrete is improved by the admixture, and is more convenient to use.
本发明涉及混凝土外加剂技术领域，公开了一种用于高强度高性能混凝土外加剂，由以下重量百分比的原料制成：非极性溶剂：50‑60％、水溶性钙盐：10‑15％、乳化剂：3‑5％、助稳定剂：0.5‑1％、硅酸四乙酯：8‑11％、氨水：0.1‑0.2％、水：10‑28％；同时公开了一种用于高强度高性能混凝土外加剂的制备方法，在进行制备该外加剂时，先将混合制备好的溶液与添加有乳化剂和助稳定剂的非极性溶液在25‑40℃的条件下水浴混合搅拌，并通过超声乳化仪进行预乳化处理，对乳化后的溶液在进行升温破乳处理，使得制备的外加剂在添加进混凝土中时，能够更加均匀的与混凝土进行混合，提高本外加剂对混凝土强度的提升，且更加方便进行使用。
