Fly Ash-Based Lightweight Geopolymer Mortars for Fire

The present study aims to investigate the use of geopolymer mortars as passive fire protection system for steel structures. Coal fly ashes were used as aluminosilicate source and perlite was employed as aggregate to obtain a lightweight system. In addition, a geopolymer mortar containing quartz aggregate was produced for comparison.

CONCRETE Optimizing the Use of Fly Ash in Concrete

covering fly ash is CSA A3001 Cementitious Materials for Use in Concretewhich separates fly ash into three types based on the calcium content of the fly ash as shown in Table 3. The calcium content of the fly ash is perhaps the best indicator of how the fly ash will behave in concrete (Thomas 1999), although other compounds such as the alkalis

Use of Biomass Gasification Fly Ash in Lightweight

Fly ash from biomass gasification differs considerably from conventional combustion ashes. Gasification ash might contain high concentrations of unburned carbon and harmful, soluble compounds. This restricts direct ash utilization and makes some pretreatment necessary, representing a significant share of the overall operating cost of gasification-based systems for energy production.
