Water-resistant magnesium phosphate repair mortar based on industrial waste residues and preparation method of water-resistant magnesium phosphate repair mortar
The invention discloses water-resistant magnesium phosphate repair mortar based on industrial waste residues and a preparation method of the water-resistant magnesium phosphate repair mortar. The water-resistant magnesium phosphate repair mortar comprises a mineral admixture, monopotassium phosphate, magnesium oxide, quartz sand, organic silica gel, a retarder and mixing water, the mineral admixture is formed by compounding steel slag, nickel slag and fly ash. During preparation, the monopotassium phosphate, the retarder and the mixing water are firstly mixed and stirred, then the mineral admixture, the magnesium oxide and the organic silica gel are sequentially added and rapidly stirred, and finally the quartz sand is added and stirred. When the repairing mortar is applied, the setting time is greater than or equal to 23 minutes, the fluidity is greater than or equal to 195mm, the 3h compressive strength is greater than or equal to 25.2 MPa, the 3d compressive strength is greater than or equal to 47.4 MPa, the 3h breaking strength is greater than or equal to 3.6 MPa, the 3d breaking strength is greater than or equal to 6.1 MPa, and the 1d tensile adhesive strength is greater than or equal to 0.8 MPa; and the water absorption ratio can reach 0.15 or below.
本发明公开了一种基于工业废渣的耐水型磷酸镁修补砂浆及其制备方法，包括矿物掺合料、磷酸二氢钾、氧化镁、石英砂、有机硅凝胶、缓凝剂及拌和水；矿物掺合料由钢渣、镍渣与粉煤灰复配而成。制备时先将磷酸二氢钾、缓凝剂、拌和水混合搅拌，再依次加入矿物掺合料、氧化镁、有机硅凝胶快速搅拌，最后加入石英砂搅拌。本发明的修补砂浆应用时凝结时间≥23min，流动度≥195mm，3h抗压强度≥25.2MPa，3d抗压强度≥47.4MPa，3h抗折强度≥3.6MPa，3d抗折强度≥6.1MPa，1d拉伸粘结强度≥0.8MPa；且吸水率比能够达到0.15以下。
