に従って、水和水の一部を追い出す。
(初期重量−最終重量)÷初期重量×100=ブリーディング水(%)
密度(lb/ft3)=(立方体の重量×0.47598)÷立方体の数
床の下張り製品において使用するのに適した石膏セメント配合物を、本発明に従って製造した。β型焼成石膏を、かなりの量のα型焼成石膏の代わりに使用し、約0.025%〜約10%のポリカルボキシレートを添加して高品質製品を製造した。
種々の供給源の石膏を用いて、いくつかの床配合物を作製し、試験した。表III−A及びIII−Bに示すように、高強度床材料は、種々の焼成石膏を用いて、種々の水分レベルで作製することができ、それでもなお、砂安定性が良好であり、ブリーディング水が少ない。
高強度の上塗りを、表IVの材料から作製した。すべての測定はポンドで行った。
