Integrated drilling and sealing material
The invention discloses an integrated drilling and sealing material. The integrated drilling and sealing material comprises the following components in percentage by weight: 35-50% of water, 60-75% ofordinary Portland cement, 1.2-1.7% of aluminum powder microcapsules and 1.0-2.0% of a high-efficiency air-entraining and water-reducing agent, the aluminum powder microcapsule contains 88-93% of water, 1-3% of gelatin, 2% of sodium alginate and 3-7% of aluminum powder, has good fluidity before initial setting, and can well fill cracks and holes in drilled holes; and after solidification, the material has the characteristics of high compressive strength, the good sealing performance, good durability and weak drainage capacity, and can meet the requirements of integrated drilling.
本发明公开了一种一体化钻孔封孔材料，该组成按重量百分比计分别为：水35‑50%，普通硅酸盐水泥60‑75%，铝粉微胶囊1.2‑1.7%，高效引气减水剂1.0‑2.0%；所述铝粉微胶囊含有水88‑93%，明胶1‑3%，海藻酸钠2%，铝粉3‑7%，本发明材料初凝前具有良好的流动性，能够很好地填充钻孔内的裂隙、孔洞；材料凝固后具有抗压强度高、密封性好，耐久性好，析水能力弱的特点，能够满足一体化钻孔的要求。
