活性炭-矿渣基导电地质聚合物的制备及性能研究

Study on Preparation and Properties of Activated Carbon-slag Based Conductive Geopolymer

以矿渣为原料,活性炭为导电相,水玻璃为激发剂制备了活性炭-矿渣基导电地质聚合物,考察了活性炭掺量对地质聚合物标准稠度、凝结时间、抗压强度和电阻率的影响。结果表明,随着活性炭掺量的增加,地质聚合物的标准稠度和凝结时间都有所延长,抗压强度先增加后减小,电阻率呈先下降后升高的趋势。当活性炭掺量为5%时,样品电阻率为17.2Ω·m,显示出较好的导电性,且抗压强度可达100.63MPa。

Activated carbon-blast furnace slag (BFS) geopolymers were prepared by using BFS as the raw material,using the activated carbon as conductive phase and using water glass as alkali activator.The effects of amount of activated carbon on the standard consistency,the setting time,the compressive strength and the resistivity of geopolymer were studied.The results indicate that the standard consistency and setting time are prolonged,the compressive strength first increases and then decreases,and the resistivity is decreased firstly and then increased with the increasing of the activated carbon content.When the amount of activated carbon is 5%,the geopolymer samples lower resistivity of 17.2 Ω·m,better conductivity and higher compressive strength of 100.63 MPa.
