Tunnel lining grouting material
The invention relates to a tunnel lining grouting material, which is prepared from the following components in parts by weight: 1434 parts of Portland cement, 141 to 230.1 parts of sulphoaluminate cement and 1246 to 1320 parts of quartz sand, less than or equal to 70.8 parts by weight of silica fume; 88.5 to 159.3 parts by weight of floating beads; 3.98 to 4.67 parts by weight of a water reducing agent; 0.708 to 1.77 parts by weight of an expanding agent; 0.177 to 0.531 parts by weight of a defoaming agent; 2.65 to 6.55 parts by weight of a retarder; 0.0885 to 0.177 part by weight of a latex powder; 0.0885 to 0.177 part by weight of welan gum; and 550 to 610 parts by weight of water. The prepared tunnel lining grouting material has the advantages of being good in fluidity, high in early strength, micro in expansion and good in bonding performance.
一种隧道衬砌注浆材料，包括：1434重量份的硅酸盐水泥，141至230.1重量份的硫铝酸盐水泥，1246至1320重量份的石英砂；小于等于70.8重量份的硅灰；88.5至159.3重量份的漂珠；3.98至4.67重量份的减水剂；0.708至1.77重量份的膨胀剂；0.177至0.531重量份的消泡剂；2.65至6.55重量份的缓凝剂；0.0885至0.177重量份的乳胶粉；0.0885至0.177重量份的温轮胶；550至610重量份的水。本发明制备而成的隧道衬砌注浆材料具有流动性好、高早强、微膨胀、结合性好的优势。
