Recycled aggregate fiber reinforced sprayed concrete and preparation method thereof
The invention discloses recycled aggregate fiber reinforced sprayed concrete. The sprayed concrete is prepared from the following raw materials in parts by weight: 100 parts of a cementing material, 75-85 parts of cement, 12-15 parts of fly ash, 6-8 parts of silica fume,150-168 parts of 5-10mm gravel, 39-42 parts of 5-10mm recycled coarse aggregate, 193-203 parts of sand, 18-23 parts of 0.15-5mm recycled fine aggregate, 6-8 parts of polypropylene fibers, 40-45 parts of mixing water, 1.5-4.5 parts of a water reducing agent, 0.1-1 part of a thickening agent and 6-8 parts of an accelerator. The invention also discloses a preparation method of the recycled aggregate fiber reinforced sprayed concrete. The sprayed concrete provided by the invention has good crack resistance, impermeability and corrosion resistance, and also has the characteristics of rapidness, early strength, simple construction process and the like.
本发明公开了一种再生骨料纤维增强喷射混凝土，包括如下组分的原料制备而成，具体组分为：胶凝材料100份，水泥75～85份，粉煤灰12～15份，硅灰6～8份，5～10mm碎石150～168份；5～10mm再生粗骨料39～42份，砂193～203份，0.15～5mm再生细骨料18～23份，聚丙烯纤维6～8份；拌合水40～45份，减水剂1.5～4.5份，增稠剂0.1～1份，速凝剂6～8份。本发明还公开了一种再生骨料纤维增强喷射混凝土的制备方法。本发明的喷射混凝土具有良好的抗裂性、抗渗性及抗腐蚀性，同时，具有快速、早强、施工工艺简单等特点。
