GEOPOLYMER COMPOSITION AND MORTAR OR CONCRETE OR SECONDARY CONCRETE PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a geopolymer composition that can prevent significant reduction of workability (e.g., trowel releasability) while ensuring the practical formulation in which the strength of a fly ash-based geopolymer is improved with a blast furnace slag, as well as a mortar or concrete or secondary concrete product.SOLUTION: The geopolymer composition is produced by mixing a filler composed of a fly ash and a blast furnace slag; an alkali solution; and an aggregate, and then curing and hardening the mixture. The particle size is adjusted by substituting a portion of the fly ash as a filler with a certain amount of silica fume.
