Alkali-activated material for repairing concrete cracks and preparation method of alkali-activated material
The invention discloses an alkali-activated material for repairing concrete cracks and a preparation method of the alkali-activated material. The alkali-activated material comprises the following components: 30%-50% of modified S95 mineral powder, 10%-20% of natural gypsum, 5%-10% of quick lime, 10%-20% of I-grade fly ash, 3%-5% of nano SiO2 and 0%-30% of steel slag powder. A net structure is formed through cross lapping of gel substances so as to form certain strength, on one hand, the addition of natural gypsum can play a role in assisting in grinding, on the other hand, a mechanochemical coupling effect can be generated so as to further improve the activity of mineral powder, and on one hand, the doping of I-grade fly ash and nano SiO2 can form a tightest stacking state to formoverlap effect, and on the other hand, the fluidity and the early strength of the material are further improved.
本发明公开了一种用于混凝土裂缝修复的碱激发材料及其制备方法，由以下组分构成：改性后S95矿粉：30％‑50％，天然石膏：10％‑20％，生石灰：5％‑10％，I级粉煤灰：10％‑20％，纳米SiO2：3％‑5％，钢渣粉：0％‑30％，本申请通过凝胶物质交叉褡裢形成网状结构从而形成一定强度，天然石膏的加入一方面可以起到助磨效果，另一方面可以产生机械‑化学耦合作用从而进一步提高矿粉活性，I级粉煤灰以及纳米SiO2的掺入一方面可形成最紧密堆积状态，形成“超叠效应”，另一方面进一步提高材料流动度以及早期强度。
