Recycled concrete with excellent impermeability and preparation method of recycled concrete
The invention discloses recycled concrete with excellent impermeability and a preparation method of the recycled concrete. The concrete with excellent impermeability is prepared from the following components in parts by weight: 240 to 300 parts of cement, 100 to 160 parts of fly ash, 120 to 180 parts of modified recycled aggregate, 15 to 25 parts of montmorillonite, 5 to 10 parts of naphthalene water reducer, 3 to 8 parts of micron calcium sulfate whisker, 6 to 12 parts of modified halloysite nanotube, 3 to 6 parts of VAE emulsion, 8 to 10 parts of fiber and 90 to 120 parts of water. After thePortland cement, the sulphoaluminate cement, the fly ash, the modified recycled aggregate, the montmorillonite, the micron calcium sulfate whisker, the modified halloysite nanotube and the fiber areused as base materials of the recycled concrete, and are matched with a naphthalene water reducer, a VAE emulsion and the water to be used as auxiliary materials, all the raw material have a synergistic effect, and the finally prepared recycled concrete has excellent water-retaining property, permeation resistance and compressive strength; and the recycled concrete is green and environment-friendly in the preparation process, has good applicability and is suitable for large-scale popularization and application.
本发明公开了一种具有优异抗渗性的再生混凝土及其制备方法，该具有优异抗渗性的再生混凝土按重量份计，包括以下组分：水泥240～300份、粉煤灰100～160份、改性再生骨料120～180份、蒙脱土15～25份、萘系减水剂5～10份、微米硫酸钙晶须3～8份、改性埃洛石纳米管6～12份、VAE乳液3～6份、纤维8～10份和水90～120份。本发明通过以硅酸盐水泥、硫铝酸盐水泥、粉煤灰、改性再生骨料、蒙脱土、微米硫酸钙晶须、改性埃洛石纳米管以及纤维为再生混凝土的基材，再配合萘系减水剂、VAE乳液以及水作为辅料使用后，各个原料之间协同增效，使得最终制备的再生混凝土具有优异的保水性能、抗渗透性能以及抗压强度，且制备过程中绿色环保，具有良好的应用性，适合大规模推广应用。
