PHC tubular pile non-autoclaved concrete active powder and preparation method thereof
The invention discloses PHC tubular pile non-autoclaved concrete active powder. The PHC tubular pile non-autoclaved concrete active powder comprises, by mass, 35%-65% of granulated blast furnace slagpowder, 20%-45% of fly ash, 5%-15% of silica fume, 5%-35% of microbeads, 5%-20% of gypsum powder, 5%-25% of nickel slag powder and 0.01%-5% of an early strength agent. A preparation method of the active powder comprises the following steps: putting the granulated blast furnace slag powder, the fly ash and the nickel slag powder into a ball mill, grinding for 20-40 minutes until the specific surface area is 400-450 m<2>/kg, and mixing the obtained powder with the silica fume, the microbeads, the gypsum powder and the early strength agent in a mixer for 15-25 minutes. The PHC tubular pile non-autoclaved concrete active powder can ensure the early and later strength of concrete, shorten the steam curing time, improve the production efficiency, enhance the durability of the concrete, and obtain favorable social and economic effects.
本发明公开了一种PHC管桩免蒸压混凝土活性粉，其包含如下质量百分比的组分：粒化高炉矿渣粉35%～65%，粉煤灰20%～45%，硅灰5%～15%，微珠5%～35%，石膏粉5%～20%，镍渣粉5%～25%，早强剂0.01%～5%。其制备方法是将粒化高炉矿渣粉、粉煤灰、镍渣粉投入球磨机粉磨20min～40min，粉磨至比表面积为400m2/kg～450m2/kg，再与硅灰、微珠、石膏粉、早强剂在混料机中混合15min～25min即可制得。本发明的一种PHC管桩免蒸压混凝土活性粉既能保证混凝土的早后期强度，又能缩短蒸养时间，提高生产效率，还能增强混凝土的耐久性，可取得良好的社会经济效应。
