Anti-radiation concrete screw hole plugging filler
The invention provides an anti-radiation concrete screw hole plugging filler, which comprises ordinary Portland cement, fly ash, quartz sand, silica powder, an optional medium-ash cement adjusting agent, water, and (a) metakaolin and magnesium oxide or (b) an emulsion. The anti-radiation concrete screw hole plugging filler has good shrinkage resistance and bonding capacity, and no shrinkage traceexists on the edge of a screw hole visually after the screw hole is plugged by the filler for 28 days.
本发明提供了一种防辐射混凝土螺杆孔封堵填充料，所述螺孔填充料包含普通硅酸盐水泥、粉煤灰、石英砂、二氧化硅粉、任选的中灰水泥调剂和水，以及(a)偏高岭土和氧化镁或(b)乳液。本发明的防辐射混凝土螺杆孔封堵填充料具有良好的抗收缩和粘结能力，填充料封堵螺杆孔28天后目视螺孔边缘无收缩痕迹。
