Cement mortar admixture as well as preparation method and use method thereof
The invention discloses a cement mortar admixture as well as a preparation method and a use method thereof, and the cement mortar admixture is prepared from the following raw materials in parts by weight: 25-35 parts of limestone powder, 15-30 parts of metakaolin, 5-15 parts of waterborne epoxy resin, 5-12 parts of silane modified nano silicon dioxide, 5-9 parts of poly dimethyl diallyl ammonium chloride and 4-10 parts of lignin fiber. The concrete is prepared from the following raw materials in parts by weight: 100 parts of water, 3-10 parts of sodium dodecyl benzene sulfonate, 0.4-0.9 part of a water reducing agent, 6-10 parts of potassium methyl silicate and 150 The admixture promotes the cement mortar to permeate into the concrete, the lignin fibers and the silane modified nano silicon dioxide are added, the mechanical property of the material can be greatly improved, and when the cement mortar and the admixture are mixed according to the weight ratio of 1: 0.02, the water retention, water reduction and waterproof characteristics of the cement mortar are fully exerted, and meanwhile, the cement mortar and the admixture are mixed at the same time. The strength of the cement mortar is improved, the sound insulation effect is good, and the corrosion resistance is good.
本发明公开了一种水泥砂浆外加剂及其制备方法、使用方法，其组分原料按重量份计包括：石灰石粉25～35份、偏高岭土15～30份、水性环氧树脂5～15份、硅烷改性纳米二氧化硅5～12份、聚二甲基二烯丙基氯化铵5～9份、木质素纤维4～10份，十二烷基苯磺酸钠3～10份、减水剂0.4～0.9份、甲基硅酸钾6～10份、水150～250份。该外加剂促进水泥砂浆渗入混凝土内部，其中加入木质素纤维和硅烷改性纳米二氧化硅，能极大程度增加材料的力学性能，在水泥砂浆和外加剂按重量比1:0.02混合时，在充分发挥水泥砂浆具有保水、减水和防水特性的同时，还提高水泥砂浆的强度，其隔音效果好，耐腐蚀性能佳。
