Method for manufacturing exterior material of concrete substitute building using waste glass fiber and building exterior material

摘要

The present invention relates to a method for manufacturing an exterior material for a building substitute for concrete using waste glass fiber, comprising: a first step (S10) of repairing the waste glass fiber and preparing an additive raw material for the exterior material by classifying it according to the residue of foreign substances; a second step (S20) of preparing an activator that induces a reaction between the main raw material for the exterior material and the geopolymer; a third step (S30) of mixing 25 to 35 wt% of an active agent and 1.0 to 5.0 wt% of an additive to 67 to 73 wt% of the prepared main raw material; A fourth step (S40) of injecting the mixture into a mold of a set shape and curing the mixture at 25 to 60° C. for 3 to 8 hours to complete the exterior material (S40). Therefore, the present invention has the effect of using household waste incineration ash or molten slag as a main raw material, and using waste glass fiber as an additive raw material to prevent environmental pollution while supplying exterior materials at a low cost.
