Early-strength and later-strength grouting material and preparation method thereof
The invention relates to the technical field of building materials, in particular to an early-strength and later-high-strength grouting material and a preparation method thereof.The early-strength and later-high-strength grouting material is prepared from Portland cement, fly ash, superfine slag micropowder, quartz sand, sodium silicate, silica fume, rubber powder, a water reducing agent, a defoaming agent, an expanding agent, a dispersing agent, an anti-freezing agent and water; according to the invention, the sleeve grouting is prepared by adopting an optimized raw material ratio and double-doping superfine slag micropowder and fly ash, the grouting material has the advantages of early strength and later-stage high strength at the same time by adding the optimized functional aids such as a water reducing agent, a defoaming agent, an expanding agent, a dispersing agent and an anti-freezing agent of the grouting material, the compressive strength can reach 85 MPa within 3 days and reach 110 MPa or more within 24 days, and the grouting material has the advantages of high early strength and high later-stage strength. The working performance such as the strength of the grouting material is obviously improved.
本发明涉及建筑材料技术领域，具体的涉及一种早强后高强灌浆料及其制备方法，其中早强后高强灌浆料组成原料包括：硅酸盐水泥、粉煤灰、超细矿渣微粉、石英砂，硅酸钠、硅灰、胶粉、减水剂、消泡剂、膨胀剂、分散剂，抗冻结剂、水，本发明采用优化的原料配比，采用超细矿渣微粉与粉煤灰双掺制备套筒灌浆，通过添加优化的灌浆料的减水剂、消泡剂、膨胀剂、分散剂，抗冻结剂等功能能助剂，使灌浆料同时具有早强和后期高强的优点，抗压强度可以在3d达到85Mpa，在24d达到110MPa以上，显著提高灌浆料的强度等工作性能。
