Early-strength nano mineral admixture for concrete and preparation method thereof
The invention discloses an early-strength nano mineral admixture for concrete, which relates to the field of early-strength nano mineral admixtures and comprises the following components in percentageby weight: 99.0-99.5 percent of fly ash, 0.1-0.5 percent of nano carbon material, 0.05-0.10 percent of grinding aid, 0.05-0.15 percent of water retaining agent, 0.05-0.15 percent of water reducing agent and 0.05-0.20 percent of retarder. The invention also relates to a preparation method which comprises the following steps: mixing the fly ash, the nano carbon material and the grinding aid, and grinding the mixture until the specific surface area is 800-1000 m2/kg to obtain a material A; mixing the water-retaining agent, the water reducing agent and the retarder to obtain a material B; and mixing the materials A and B to obtain the early-strength nano mineral admixture. The early strength type nano mineral admixture can improve the working performance and workability of concrete, improve the early strength and later strength of the concrete and improve the durability of the concrete.
本发明公开了一种用于混凝土的早强型纳米矿物掺合料，涉及早强型纳米矿物掺合料领域，按重量比计，包括：粉煤灰99.0‑99.5％，纳米碳材料0.1～0.5％，助磨剂，保水剂0.05‑0.10％，减水剂0.05～0.15％，缓凝剂0.05～0.20％。本发明还涉及一种制备方法，包括：粉煤灰、纳米碳材料、助磨剂混合并粉磨比表面积至800‑1000m2/kg得到物料A；保水剂，减水剂，缓凝剂混合得到物料B；混合A和B，得到早强型纳米矿物掺合料。本发明早强型纳米矿物掺合料能改善混凝土的工作性能及和易性，提高混凝土早期和后期强度，提高混凝土耐久性。
