铜陵县耐磨灌浆料#价格 1. Introduction介绍 1.1 Description描述 Micro-fine cement is Portland cement based cements composed of ultrafine particles and are designed for injection into loose soils, rock and concrete. Because of micro-fine cement’s small particle size (the fineness largest grain size passing D95 is 16.0 μm and Blaine value 600 m2/kg.), it penetrates very well into tight joints, fissures and pore spaces to provide a water-tight grouted rock or soil mass. It can be used as grouting materials after adding water reducing agent (GC1). 超细水泥是经特殊设备精细研磨而成的新一代无机刚性超细材料，利用超细水泥再添加其他外加剂(例如GC1减水剂)、掺合料搅拌而成的浆液，可以用于补强加固工程的灌注作业。 1. 2Application应用范围 · Rock injection: Tunnels, cer, mines, etc. used for pre- and post excation injection. · Ground water sealing and ground stabilization. · Soil injection. · Dam foundation injection · Prepacked injection. · Contact injection. ．水利工程中大坝坝体及坝基裂缝灌浆； ．灌筑地下防水帷幕，截断渗透水源，整体抗渗堵漏； ．加固和土及岩石的力学强度，修复砼结构和恢复其整体性； ．纠正因地层不引起不均匀沉降而的大坝和高层建筑物的开裂、倾斜； ．公路、桥梁、跑道等地基下陷的补浆加固； ．各种地下建筑物开挖前的预处理以及地质钻探中复杂地层钻孔中的护孔固壁，止涌堵漏等工程； ．复杂地层的流沙层固沙及淤泥质土层的固结。 1.3 Features and benefits产品优点 · Fast setting time. · Fine particle size · Durable. · Economical solution. · Non-hazardous · Standard cement injection equipment can be used. · Better penetration in tight joints, fissures and pore spaces. · Greater penetration imparts greater water tightness. · Excellent penetration in tight joints, fissures and pore spaces · Better working environment and no hazardous components. · Better working environment. · Improved grouting efficiency and less waste · 超细水泥材料、无味、对地下水及无污染，属环保型材料。 · 超细水泥可以配合其他掺和料、助剂使用，搅拌而成的浆液固化时无收缩现象，结石强度高，耐久性好，不老化，抗渗性能佳。 · 超细水泥材料的比表面积在600㎡/㎏以上，平均粒径10μm以下，可使浆液流动性好，因而其性及可灌性高。 1.4 Packaging包装及储存 Micro-fine cement is supplied in 25 kg stic bags for ease of handling and to maximize storage life. 包 装：采用纸塑复合袋包装， 25公斤／袋； 贮 存：须贮存于干燥通风的室内，编织袋密闭，注意防潮、防冻； 保质期：6个月。 2 Performance Characteristics High-pressure piston pumps are normally used to pump the suspeion into the rock. The grout should be injected within6HOU after mixing to eure that it keeps penetrating into the fissures. 针对不同大小的缝隙空间．不同土壤地质，不同的灌浆基础条件，不同的强度指标要求确定适宜的水灰比(通常注浆料水灰比的范围为0.5—3.0) ）进行搅拌5分钟以上。 可采用手动或电动水泥灌浆设备进行灌浆作业，注浆压力在一定的范围内(通常在0.1-0.5MPa范围内。不同的基础条件，不同的水灰比，所需的注浆压力不同。注浆压力太大，可能形成劈裂注浆，无法均匀渗透。灌浆压力太小，则无法渗透至细微空间. 2.1 Technical Data PRODUCT 产品名称 Unit 单位 MFC-600 MFC-800 MFC-1200 Appearance 外观 Grey Powder 灰色粉末 Grey Powder 灰色粉末 Grey Powder 灰色粉末 Odor气味 none无 none无 none无 Toxic毒性 none 无 none无 none无 Deity 密度 kg/dm3 ~3 ~3 ~3 Specific Surface Area比表面积 ㎡/kg ≥600 ≥800 ≥1200 Grain Size 中位粒径D50 μm ＜8.96 ＜4.66 ＜3.21 Grain Size中位粒径 D90 μm ＜26.92 ＜13.31 ＜7.55 Grain Size中位粒径 D95 μm ＜32.00 ＜16.00 ＜10.51 Setting Times （Measured by Vicat needle）凝结
