PLA MANUFACTURING METHOD OF FLY ASH-BASED GEOPOLYMER OPEN POROUS MATERIAL USING PLA FIBERS

摘要

The present invention relates to a method for manufacturing a fly ash-based geopolymer porous material having continuous pores using biodegradable polymer polylactic acid (PLA) fibers. The PLA fibers are mixed and cured in a fly ash-based geopolymer, and decomposed and removed during a curing process using properties of which the PLA fibers are decomposed at curing temperature conditions and strong alkali environments to produce the fly ash-based geopolymer porous material having continuous pores. The fly ash-based geopolymer porous material has the continuous pores having the porosity of 20% or more and has no reaction with reactants at room temperature, thereby being useful for water and air purification since the pores are not deformed.
