Description
以下の表1に記載する配合割合にて本発明品及び比較品の配合物を作製し、得られた配合物に所定量の水を添加し、万能ミキサーにて混練した後、40mm×40mm×160mmの型枠に流し込み、硬化、脱枠後、110℃で24時間乾燥して供試体を得た。
得られた供試体について、線変化率、曲げ強さ、かさ比重並びに熱伝導率を次に示す方法により測定した:
線変化率:JIS R2554に準じ、1000℃焼成後の供試体について測定した;
曲げ強さ:JIS R2553に準じ、1000℃焼成後の供試体について測定した;
かさ比重:JIS R2205に準じ、焼成後の供試体について測定した;
熱伝導率:115×114×65mmの供試体を1000℃で3時間焼成した後、熱線法により測定した。
得られた結果を表1に併記する。
