台灣本島水庫淤泥中含有大量矽鋁酸鹽礦物,可應用於無機聚合膠結材之原料。本研究使用30%爐石粉與70%煅燒水庫淤泥之混合物,並添加氫氧化鈉及液態矽酸鈉所配置之鹼活化液加以攪拌,再採用機械發泡方式,製作不同密度及厚度之發泡無機聚合物,然後進行一系列物理、力學及聲學試驗之量測。無機聚合物之水膠比為0.4及0.5,設計密度則為1.0、0.9、0.8及0.7 ,分別量測不同密度及水膠比發泡無機聚合物之吸水率、孔徑分佈、抗壓強度及抗彎強度等。另外,製作厚度為10及6cm之發泡無機聚合物單層板,量測並比較不同密度及厚度發泡無機聚合物之噪音穿透損失值,進而獲得發泡無機聚合物之最佳厚度及密度。
試驗結果發現,不同密度和厚度之發泡無機聚合物,其噪音穿透損失值遵守質量定律,發泡無機聚合物之最佳密度為1.0 ,最佳厚度則為10cm。同時,此次試驗結果與煅燒高嶺土發泡無機聚合物相互比較,發現煅燒水庫淤泥發泡無機聚合物之穿透損失值,優於煅燒高嶺土發泡無機聚合物,尤其在高頻部分。
The reservoir sludge in Taiwan, with large amounts of silicate minerals, can be used as a raw material for the production of inorganic polymers. In the study, a combination of 30% slag and 70% calcined reservoir sludge was first mixed with an alkali activating solution of sodium hydroxide and sodium silicate and then foamed mechanically to make foamed inorganic polymers with various density and thickness. At last, a series of physical, mechanical and acoustic tests were conducted to measure the water absorption, cell size distribution, compressive strength and flexural strength of foamed inorganic polymers with two water/binder ratios of 0.4 and 0.5 and various densities of 1.0, 0.9, 0.8 and 0.7 . Meanwhile, the transmission losses of foamed inorganic polymers with two different thicknesses of 10 and 6cm and various densities were measured and then compared to determine their optimal thickness and density.
Based on our experimental results, it was found that the transmission loss of foamed inorganic polymers follow the mass law and the optimum density is 1.0 while the optimum thickness is 10cm. Also, the transmission loss of foamed inorganic polymers made from calcined reservoir sludge is superior to those made from calcined metakaolin, especially in the range of high frequency.
