电石渣掺量对矿用充填胶固粉性能影响研究

Research on Effect of Dosage of Carbide Slag on the Performance of Filling Cementing Powder

为了在矿用充填材料中更加合理的利用电石渣,本文在粉煤灰、水泥熟料、钢渣等掺量不变的情况下,研究电石渣掺量0%、0.5%、1%、1.5%、2%时对胶固粉浆体的凝结时间、抗压强度、流动性、微观结构、水化产物的影响。试验结果表明:在凝结时间方面,随着电石渣掺量的增加,凝结时间随之减少;在抗压强度方面,1%掺量的电石渣组相比较其他掺量组使胶凝材料的强度最高;能够生成更多的水化产物;通过SEM观测表明,胶凝材料的微观结构更加致密。

In order to use carbide slag in the ore filling materials more reasonably,on the condition of the normal dosage of fly ash,cement clinker and slag,the effect of the dosage of carbide slag of 0%、0. 5%、1%、1. 5%、2% on the setting time,compressive strength,fluidity,the influence of the microstructure and hydration products was studied.The test results show that in terms of setting time,with the increase of dosage of carbide slag,the setting time is less and in terms of compressive strength,compared with other dosage groups of gelled material,1%of calcium carbide slag dosage group has the highest strength and can generate more hydration products.SEM showed that the gel material had more dense microstructure.
