Dry-mixed mortar and preparation method thereof
The invention discloses dry-mixed mortar. The dry-mixed mortar comprises ordinary Portland cement, coal ash, diabase powder, quartz sand, titanium iron ore powder, sepiolite powder, short carbon fibers, citric acid residue powder, a polymer, a polycarboxylate superplasticizer, etherified starch and thickening powder. Specifically, the dry-mixed mortar comprises the following components in parts by weight: 90 to 110 parts of the ordinary Portland cement, 30 to 50 parts of the fly ash, 8 to 10 parts of the diabase powder, 720 to 840 parts of the quartz sand, 3 to 5 parts of the titanium iron ore powder, 6 to 8 parts of the sepiolite powder, 2 to 3 parts of the short carbon fibers, 12 to 15 parts of the citric acid residue powder, 10 to 30 parts of the polymer, 0.5 to 1.0 part of the polycarboxylate superplasticizer, 0.3 to 0.5 part of the etherified starch and 3 to 5 parts of the thickening powder. The prepared dry-mixed mortar is relatively good in crack resistance and relatively strong in water retention effect; and when the dry-mixed mortar is being prepared and the raw materials are stirred, flying of raw material dust cannot be caused, and rapid discharging is facilitated.
本发明公开了一种干混砂浆，包括普通硅酸盐水泥、粉煤灰、辉绿岩粉、石英砂、钛铁矿石粉、海泡石粉、短切碳纤维、柠檬酸渣粉、聚合物、聚羧酸减水剂、醚化淀粉和稠化粉，所述干混砂浆的重量组分为：普通硅酸盐水泥90～110份、粉煤灰30～50份、辉绿岩粉8～10份、石英砂720～840份、钛铁矿石粉3～5份、海泡石粉6～8份、短切碳纤维2～3份、柠檬酸渣粉12～15份、聚合物10～30份、聚羧酸减水剂0.5～1.0份、醚化淀粉0.3～0.5份、稠化粉3～5份。制备出的干混砂浆抗裂性能较好，且备出的干混砂浆保水效果较强，并且在制备干混砂浆时，搅拌原料时，不会造成原料粉尘的飞扬，以及便于快速出料。
