摘 ? 要:研究了石材加工產生的廢石粉替代部分水泥對3D打印水泥砂漿性能的影響。結果表明:總體上,隨著廢石粉摻量的增加,砂漿的流動度降低,靜態屈服應力提高,但凝結時間變化不明顯;通過調整減水劑摻量可以改善廢石粉對3D打印水泥砂漿流動性和可建造性的不利影響;廢石粉的摻入對3D打印水泥砂漿的力學性能和層間界面黏結強度不利。
Abstract: The effect of replacing part of cement with waste stone powder produced by stone processing on the performance of 3D printing cement mortar was studied. The results show that with the increase of the waste stone powder content, the fluidity of cement mortar decreases and the static yield stress increases in general, but the setting time does not change significantly. The adverse effect of waste stone powder on the fluidity and constructability of 3D printing cement mortar can be improved by adjusting the amount of water reducing agent. The incorporation of waste stone powder is detrimental to the mechanical properties and interface bonding strength of 3D printing cement mortar.
