廃石こうボードの再資源化に関する実験的研究

Abstract

Plaster board is produced in large quantities in Japan. Therefore quantity of disposal increases, too. Therefore I examine recycling of plaster board. I crush a plaster board and plaster powder it. I use the plaster powder which I separate paper and plaster powder and took out. I add plaster powder and cement and water, and examine the thing which hardened as product. I do unconfined compression test and a flexure test of this plaster product. Furthermore, I measure an effect as a water retentive block. I suggest a superior product to water retentive power, than these test results.
