Steel slag powder-doped micro-expansion grouting material for sleeve, and preparation and expansion effect detection methods thereof
The invention relates to a steel slag powder-doped micro-expansion grouting material for a sleeve, and preparation and expansion effect detection methods thereof. The steel slag powder-doped micro-expansion grouting material is prepared by mixing the following components in percentage by mass: 40-45% of cement, 30-35% of steel slag powder, 1-2% of fine sand, 1-2% of a water reducing agent, 1-2% ofa retarder and 1-2% of a defoaming agent, with the balance being water. According to the invention, the steel slag powder replaces modified mineral powder; due to the expansion effect of the slag powder, an expanding agent does not need to be added; and the compactness of the sleeve filled with the sleeve grouting material and used for steel bar connection can be improved after the grouting material is used, so steel bar connection strength is further improved, and the utilization rate of resources can be increased. The quality of the grouting material for the sleeve is guaranteed through a corresponding detection mode in the preparation process.
掺入钢渣粉套筒微膨胀灌浆料及其制备和膨胀效应检测方法，本申请提供掺入钢渣粉套筒微膨胀灌浆料，由以下各组分混合而成,各组分按质量百分比构成如下:水泥：40‑45％；钢渣粉：30‑35％；细砂：1‑2％；减水剂：1‑2％；缓凝剂：1‑2％；消泡剂：1‑2％；其余为水；本发明提供掺入钢渣粉套筒微膨胀灌浆料及其制备和膨胀效应检测方法，本申请钢渣粉替代改性矿物粉料，由于矿渣粉的膨胀效应，不需添加膨胀剂，使用后可以提高钢筋连接用套筒灌浆料填充套筒的密实性，从而进一步增加钢筋连接强度，并且可以提高资源利用率，本发明制备过程中通过相应的检测方式保证套筒灌浆料质量。
