Sleeve grouting material for steel bar connection in prefabricated building field and preparation method of sleeve grouting material
The invention relates to the technical field of sleeve grouting materials, and discloses a sleeve grouting material for steel bar connection in the field of prefabricated buildings, which is prepared from the following raw materials in parts by weight: 350 to 600 parts of cement, 150 to 250 parts of blast furnace slag, 80 to 150 parts of mineral admixture, 70 to 100 parts of copper tailings, 10 to 30 parts of plastic expanding agent, 1 to 5 parts of naphthalene water reducer, 0.5 to 0.8 part of retarder and 1 to 3 parts of exciting agent. According to the sleeve grouting material for steel bar connection in the prefabricated building field and the preparation method of the sleeve grouting material, mineral aggregates such as the blast furnace slag, the mineral admixture and the copper tailings are added into the raw materials to replace a traditional quartz powder raw material so as to reduce the cost required by production of the whole slurry, and a plastic expanding agent, a naphthalene water reducer and a retarder are sequentially added into the mineral aggregates so as to reduce the cost required by production of the whole slurry. The excitant enables the mortar powder to be most closely stacked, so that the porosity of the slurry is reduced, the compressive strength of the slurry is improved, the grouting material has an early-strength and high-strength mechanism, and the hardened slurry has early-strength and high-strength performance.
本发明涉及套筒灌浆料技术领域，且公开了一种装配式建筑领域钢筋连接用套筒灌浆料，包括以下重量份数配比的原料：水泥350‑600份，高炉矿渣150‑250份，矿物掺合料80‑150份，铜尾矿70‑100份，塑性膨胀剂10‑30份，萘系减水剂1‑5份，缓凝剂0.5‑0.8份，激发剂1‑3份。该装配式建筑领域钢筋连接用套筒灌浆料及其制备方法，通过向原料中加入高炉矿渣，矿物掺合料，铜尾矿等矿料，来代替传统的石英粉原料，来降低整个浆料在生产时所需要的成本，而通过向矿料内依次加入塑性膨胀剂，萘系减水剂，缓凝剂，激发剂来使砂浆粉料达到最紧密堆积，从而降低浆料孔隙率，提高其抗压强度，使得灌浆料具有早强高强机理，硬化后浆体具有早强高强性能。
