Preparation method of ultrafine micro-nano-scale active admixture and chained grouting material
The invention provides a preparation method of an ultrafine micro-nano-scale active admixture and a chained grouting material, and the chained grouting material comprises the following components in percentage by mass: 25%-38% of cement, 5%-14% of glass beads, 2%-5% of silica fume, 5%-20% of the ultrafine micro-nano-scale active admixture, 2%-5% of high-strength fibers, 0.1%-1% of toughening fibers and 0.2%-0.4% of a polycarboxylate superplasticizer. 0%-0.02% of a defoaming agent, 0%-0.04% of a foaming agent, 28%-42% of river sand and 12%-18% of ground river sand; according to the invention, a compound of ordinary Portland cement, industrial gypsum and calcium bicarbonate is added together as an active activator of the mineral admixture, and the active activator and the high efficiency water reducer act together to excite the activity of the mineral admixture, so that active components of fly ash and slag powder in the mineral admixture are fully excited; various pores formed in the hardening process of the grouting material are filled, the void ratio of the grouting material is reduced, and the grouting material has excellent erosion resistance and durability.
本发明提供了一种超细微纳米尺度活性掺合料及链接灌浆材料制备方法,所述灌浆材料包括以下组分，按质量百分比：水泥25％～38％，玻璃微珠5％～14％，硅灰2‑5％，超细微纳米尺度活性掺合料5％‑20％，高强纤维2‑5％，增韧纤维0.1‑1％，聚羧酸减水剂0.2％～0.4％，消泡剂0％～0.02％，发泡剂0％～0.04％，河砂28％～42％，磨细河砂12％～18％；本发明通过加入普通硅酸盐水泥与工业石膏和和碳酸氢钙的复合物一起作为矿物掺合料的活性激发剂与高效减水剂共同作用来激发其的活性，使矿物掺合料中的粉煤灰、矿渣粉的活性成分得到充分的激发，填充了灌浆料硬化过程中形成的各种孔隙，降低了灌浆料的空隙率，灌浆料获得优良的抗侵蚀性和耐久性。
