Title:
ROOM-TEMPERATURE FAST-CURING GEOPOLYMER AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/120780
Kind Code:
A1
Abstract:
The present invention provides a room-temperature fast-curing geopolymer and a preparation method therefor, wherein the geopolymer has: a higher curing rate than conventional geopolymers; a flexural strength increase of 40% or more compared to conventional geopolymers, with a maximum strength of 27.83 MPa; and a compressive strength increase of 20% or more compared to conventional geopolymers, with a maximum strength of 55 MPa. The geopolymer according to the present invention has excellent heat resistance and thus is suitable for flame-retardant performance and fire spread prevention.
