Grouting material type admixture for high-strength and high-fluidity concrete and preparation method of grouting material type admixture
The invention relates to an additive, and particularly discloses a grouting material type additive for high-strength and high-fluidity concrete and a preparation method of the grouting material type additive. The invention discloses a grouting material type admixture for high-strength and high-fluidity concrete. The raw materials of the admixture comprise the following components in parts by weight: 120-160 parts of cement, 0.1-1 part of modified carbon nanotubes, 80-100 parts of lithium slag powder, 60-80 parts of water, 80-120 parts of aggregate, 1-5 parts of a water reducing agent and 0.1-1 part of a defoaming agent, the raw materials of the modified carbon nano tube comprise phenolic resin, an organic solvent and a carbon nano tube. The phenolic resin is uniformly loaded on the carbon nanotubes through the organic solvent, the phenolic resin is easily mixed with the aggregate, and the phenolic resin and the aggregate have relatively strong binding power, so that the carbon nanotubes are uniformly dispersed in the additive, the carbon nanotubes have a certain inhibition effect on a shrinkage phenomenon, and the lithium slag powder has a certain expansion effect; therefore, the strength of the formed concrete is improved.
本申请涉及一种外加剂，具体公开了一种高强度高流动性混凝土用灌浆料型外加剂及其制备方法。一种高强度高流动性混凝土用灌浆料型外加剂，所述外加剂的原料包括如下重量份的组分：水泥120~160份、改性碳纳米管0.1~1份、锂渣粉80~100份、水60~80份、骨料80~120份、减水剂1~5份、消泡剂0.1~1份；所述改性碳纳米管的原料包括酚醛树脂、有机溶剂、碳纳米管。本申请中有机溶剂使得酚醛树脂均匀负载在碳纳米管上，酚醛树脂容易同骨料混合，且与骨料具有较强的粘结力，从而使得碳纳米管均匀分散在外加剂中，碳纳米管对收缩现象具有一定的抑制作用，且锂渣粉具有一定的膨胀作用，从而提高了形成混凝土的强度。
