摘要
本文旨在研究以碱-矿渣配制高密度材料时,在不同工艺条件下仅以水玻璃作激发剂对其微观结构的影响,从而了解其性能变化规律并确定最佳工艺参数。研究表明,在W/C=0.26,水玻璃模数为1.0,掺量为10%时,其浆体28 d抗压强度可达58.2 MPa,碱-矿渣可配制成高密度材料,因其凝结时间快可用作检修材料,亦可用可溶性碳酸盐调节其凝结时间,对浆体结构密实的原因亦作了研究。
The preparation of a material from alkali-water granulated blast furnace slag was studied in different technical conditions using soluble glass as a stimulator only. The changes of microstructure of the material were observed by SEM and analysed by DTA and infrared analysis to find out the variation rules of property and to determine the optimum technical parameters. The results showed that the 28 d compressive strength of the paste was about 58 MPa with high density when W/C=0.26, modulus of soluble glass 1.0 and addition amount 10%. This material could be used as a rushing repairing material due to its quick setting, but the setting time could be regurated by adding soluble carbonate, if necessary.
