High-titanium slag micro-nano admixture for concrete and preparation method of high-titanium slag micro-nano admixture
The invention provides a high-titanium slag micro-nano admixture for concrete and a preparation method of the high-titanium slag micro-nano admixture, and relates to the technical field of concrete mineral admixtures. The high-titanium slag micro-nano admixture for the concrete comprises the following raw materials in parts by weight: 40-55 parts of high-titanium slag, 0-15 parts of active steel slag powder, 45-60 parts of silica fume and 0-1 part of an additive. The high-titanium slag micro-nano admixture provided by the invention can be better dispersed in high-strength and high-performance concrete, the cement consumption can be reduced by 10-20% under the condition of ensuring the strength requirement, and meanwhile, the high-titanium slag micro-nano admixture has reasonable micro-grain size distribution micro-aggregate, can effectively fill micro-gaps of a rubber material, and has the advantages of high strength and high performance. A denser concrete cementing surface is obtained, the dry shrinkage rate of the concrete can be effectively reduced, the problems of concrete cracking and the like are effectively reduced, and the durability of the concrete can be remarkably improved.
本发明提供一种混凝土用高钛型矿渣微纳米掺合料及其制备方法，涉及混凝土矿物掺合料技术领域。该混凝土用高钛型矿渣微纳米掺合料，包括以下质量份数的原料：高钛型矿渣40‑55重量份、活性钢渣粉0‑15重量份、微硅粉45‑60重量份和外加剂0‑1重量份。本发明提供的高钛型矿渣微纳米掺合料在高强高性能混凝土中能更好的分散性，在保证强度要求的情况下，可降低水泥用量10‑20％，同时该高钛型矿渣微纳米掺合料具有合理的微观粒度级配微骨料，可有效填充胶材的微观空隙，获得更致密的混凝土胶结面，可有效降低混凝土干缩率，有效减少混凝土开裂等问题发生，可显著提高混凝土耐久性。
