High-strength concrete grouting material and preparation method thereof
The invention discloses a high-strength concrete grouting material which is prepared from the following raw materials in parts by weight: 3 to 4 parts of cement, 0.3 to 0.8 part of slag sand, 1 to 2 parts of quartz sand, 1.5 to 2.5 parts of river sand, 0.08 to 0.15 part of a water reducing agent, 0.1 to 0.5 part of an early strength agent, 0.2 to 0.35 part of fly ash, 0.009 to 0.015 part of polyvinyl alcohol, 0.001 to 0.005 part of graphene oxide, 0.5 to 1 part of quartz powder, 0.0005 to 0.003 part of a defoaming agent, 0.7 to 1 part of water, 0.0001 to 0.0005 part of a stabilizer and 0.002 to 0.008 part of a thickening time control agent. The method comprises the following steps: screening, cleaning and air-drying the raw materials, and proportioning the raw materials in parts by weight for backup; and mixing and stirring through a pulping machine, sampling a semi-finished product formed after mixing and stirring is completed through a sampler, and allowing the sampled semi-finished product to be subjected to a fluidity test. The grouting material prepared by the invention has the beneficial effects of simple process, low cost, high strength, long service life, improvement of structural safety and the like.
本发明公开了一种高强混凝土灌浆料，包括如下重量份的原料组成，水泥3～4份、矿渣砂0.3～0.8份、石英砂1～2份、河砂1.5～2.5份、减水剂0.08～0.15份、早强剂0.1～0.5份、粉煤灰0.2～0.35份、聚乙烯醇0.009～0.015份、氧化石墨烯0.001～0.005份、石英粉0.5～1份、消泡剂0.0005～0.003份、水0.7～1份、稳定剂0.0001～0.0005份和调凝剂0.002～0.008份。将原料进行筛选、清洗和风干后按照重量份的原料进行配比备份；通过制浆机进行混合搅拌，通过取样器对混合搅拌完成后形成的半成品进行取样，对取样后的半成品进行流动性测试。通过本发明制作的灌浆料具有工艺简单、成本较低、强度高、使用寿命长和提高结构安全性等有益效果。
