Reinforcing steel bar sleeve grouting material and preparation method thereof
The invention discloses a reinforcing steel bar sleeve grouting material and a preparation method thereof. The reinforcing steel bar sleeve grouting material comprises the following components in parts by mass: 550-700 parts of cement clinker powder; 40 to 80 parts of silica fume; 200 to 400 parts of regenerated micro powder; 900 parts to 1100 parts of reclaimed sand; 12 to 20 parts of an additive; and 12 to 24 parts of an alkali solubilizing activator. The preparation method of the reinforcing steel bar sleeve grouting material comprises the following steps: 1) preparing the silicon mortar material; 2) preparing reclaimed sand-silica fume mixed mortar; and 3) mixing the cement clinker powder, the regenerated micro powder, the additive, the alkali solubilizing activator and the regenerated sand-silica fume mixed mortar. The reinforcing steel bar sleeve grouting material is excellent in performance and low in price, the mixing amount of the regenerated sand and the regenerated micro powder is large, the using amount of the cement and the quartz sand is small, and the problems of small mixing amount and low additional value utilization existing in resource utilization of the construction waste are well solved.
本发明公开了一种钢筋套筒灌浆料及其制备方法。本发明的钢筋套筒灌浆料包括以下质量份的组分：水泥熟料粉：550份～700份；硅灰：40份～80份；再生微粉：200份～400份；再生砂：900份～1100份；外加剂：12份～20份；碱增溶活化剂：12份～24份。本发明的钢筋套筒灌浆料的制备方法包括以下步骤：1)制备硅灰浆料；2)制备再生砂‑硅灰混合砂浆；3)水泥熟料粉、再生微粉、外加剂、碱增溶活化剂和再生砂‑硅灰混合砂浆的混合。本发明的钢筋套筒灌浆料性能优异、价格低廉，再生砂和再生微粉掺量大，水泥和石英砂的用量小，很好地解决了建筑垃圾资源化利用存在的掺量小、低附加值利用的问题。
