Journal ArticleDOI
Effects of Si/Al ratio on the efflorescence and properties of fly ash based geopolymer
TL;DR: In this paper, a test method of the efflorescence degree of fly ash based geopolymer was proposed and applied and the effects of the Si/Al ratio on products, microstructure, pore structures, compressive strength, water loss rate and efforescence of geopolymers were systematically investigated.
Journal ArticleDOI
Preparation, characterization and application of red mud, fly ash and desulfurized gypsum based eco-friendly road base materials
TL;DR: In this article, the authors used fly ash and desulfurized gypsum (DG) as the main raw materials to prepare road base materials based on the different (CaO+Na2O)/(SiO2+Al2O3) molar ratio, and its mechanical properties, durability, microstructure and environmental performance were investigated.
Journal ArticleDOI
Binary reaction behaviors of red mud based cementitious material：Hydration characteristics and Na+ utilization
TL;DR: New theoretical guidance for the utilization of RM and its Na+ in building materials is provided and the compressive strength of RMC is the highest and reaches 32.5R OPC.
Journal ArticleDOI
Mechanism of magnetizing the Bayer red mud and meanwhile improving the cementitious activity of its tailings by using biomass
TL;DR: In this article, the effects of biomass as reductant and alteration agent on the hematite transformed into magnetite in BRM and cementitious activity of tailings (residue after extraction of iron components, abbreviated as REIC) were systematically investigated.
Journal ArticleDOI
Effects of sulfate on the mechanical performances and hydration characteristics of red mud based non-burnt brick
TL;DR: In this paper, the effects of sulfate on the mechanical performances, hydration characteristics, internal structure and micrographs of red mud based non-burnt brick (RMNB) were studied by using red mud (RM), fly ash (FA) and desulfurized gypsum (DG).
