Application of machine-made sand in shrinkage-free high-strength grouting material
The invention discloses an application of machine-made sand in a shrinkage-free high-strength grouting material. The machine-made sand is used for replacing quartz sand to be applied to the shrinkage-free high-strength grouting material. When the water-cement ratio is 0.15 and the ratio of replacing quartz sand by machine-made sand reaches 60%, the strength of the grouting material is remarkably improved, the fluidity and workability state are good, the vertical expansion rate is slightly improved compared with a reference ratio, and plastic settlement generated in the initial stage of pouring can be effectively overcome. The grouting material has the excellent performance of high early strength, micro-expansion and no shrinkage, is simple in production process, low in cost and free of secondary pollution, can be widely applied to anchoring of foundation bolts, embedding of reinforcing steel bars, secondary grouting of equipment, reinforcement of beams, plates, columns and terraces of buildings and the like, and is wide in application range. Effective load transmission is guaranteed, high fluidity is achieved, construction time is long, early strength and high strength are achieved, construction performance is good, cost is reduced, performance is improved, and market requirements can be met.
本发明公开了一种机制砂在无收缩高强灌浆料中的应用。利用机制砂替换石英砂应用在无收缩高强灌浆料中。当水灰比为0.15且机制砂替换石英砂比例达60％时，灌浆料强度显著提高，流动度及和易性状态良好，竖向膨胀率与基准配比相比略微提升，能够有效克服浇注初期产生的塑性沉降。本发明具有早期强度高，微膨胀无收缩等优异性能，生产工艺简单，成本低廉，并且无二次污染，可广泛用于地脚螺栓锚固，栽埋钢筋，设备的二次灌浆以及建筑物的梁、板、柱和地坪的补强加固等方面，应用范围较广。保证有效传递荷载，高流动度可施工时间长，早强高强，施工性能好，既降低了成本又提高了性能，希望能满足市场的需求。
