碱-偏高岭土-矿渣水合陶瓷力学性能研究

Research on Mechanics Performance of Alkali-activated Metakaolin Slag Hydroceramic

研究了水热条件、粒化高炉矿渣掺量对碱-偏高岭土-矿渣水合陶瓷（alkali—activated metakaolin slag hydroceramic，AKSHC）力学性能和孔结构的影响；测定了当矿渣掺量为20％时，AKSHC基材的耐酸性和耐水性，研究了高碱废液掺量和水灰比对其固化体力学性能的影响。结果表明：一定范围内，矿渣能有效改善AKSHC基材力学性能；矿渣掺量增加，AKSHC基材孔体积逐渐增大，孔集中分布在15～90nm的范围内；AKSHC20固化体强度随高碱废液加入量增加、水灰比减小而提高。

Influence of hydrothermal condition and dosage of Granulated Blast-furnace Slag（GBS） on compressive strength and pore structure of alkali-activated metakaolin-slag hydroceramic（AKSHC） were researched. Property of resisted acid and water of AKSHC of 20 % dosage of GBS were investigated in NaAc-HAc and simulated ground for 120 days. Influence of dosage of simulated sodium bearing waste（SSBW） and water solid ratio on AKSHC form were researched. The results indicated that GBS would be helpful to improve compressive strength of AKSHC in some range of dosage of GBS. The total pore volume of AKSHC would be incrcasing with the increase of dosage of GBS and distributing mostly on 15- 90 nm; compressive strength of AK- SHC20 form would be increasing with the increase of dosage SSSBW and decrease of water solid ratio.
