Abstract

The manufacturing process of artificial stone was analyzed through proper composition cost of complex substances such as waste paint and waste EPS generated by industries; measures were proposed to effectively increase the utilization and recycling rate of manufactured artificial stone. Experiments on compression strength, gravity, absorption, bending strength, and thermal conductivity of manufactured artificial stone demonstrated its availability in architecture and ultimately helped to increase the recycling rate of waste paint. Manufactured waste EPS proposed a manufacturing process that allows surface membranes to form, increase weight, and enhance hardness to increase binding power with other materials. Upon analysis of two purification resources involving the manufacturing process of waste paint and waste EPS, it was revealed that waste paint was produced with a certain specification of particle size, and waste EPS formed one complex. The manufacturing composition cost of artificial stone was proposed by adding cement, silicon, polyethylene, and waste paint aggregates into three categories; the composition cost was differently evaluated to resolve the combustibility issue of polyethylene. Manufactured artificial stone showed good results in compression strength, gravity, absorption rate, and bending strength evaluation, and in particular, flame retardability evaluation showed values above Class 1 and 2, demonstrating the potential to compensate for the shortcomings of existing artificial stone.
