High-performance building support grouting material and preparation method thereof
The invention discloses a high-performance building support grouting material, which is prepared from 15 to 25 parts of Portland cement and 15 to 25 parts of sulphoaluminate cement; 1 to 5 parts of silica fume, 3 to 6 parts of mineral powder and 2 to 5 parts of fly ash; 50 to 70 parts of machine-made sand, 1 to 3 parts of phosphogypsum and 0.3 to 0.5 part of fiber; 1 to 5 parts of an expanding agent and 0.3 to 0.5 part of a water reducing agent; and 0.01 to 0.15 part of a defoaming agent and 0.3 to 0.5 part of a retarder. The grouting material disclosed by the invention can meet the construction requirements of the grouting material for the basin-type rubber support of the prefabricated box girder, and has good impermeability and wear resistance.
本发明公开了一种高性能建筑支座灌浆料，包括硅酸盐水泥15份～25份、硫铝酸盐水泥15份～25份；硅灰1份～5份、矿粉3份～6份、粉煤灰2份～5份；机制砂50份～70份、磷石膏1份～3份、纤维0.3份～0.5份；膨胀剂1份～5份、减水剂0.3份～0.5份；消泡剂0.01份～0.15份、缓凝剂0.3份～0.5份。本发明的灌浆料能够达到预制箱梁盆式橡胶支座灌浆料的施工要求，且具有良好的抗渗耐磨能力。
