不同河川地區河川淤泥之化學與物理性質差異甚大，有些河川淤泥主要成分為黏土，有些則以砂為主，另外，由於河川所受汙染來源與程度不同，河川淤泥中之雜質，可能包括重金屬、塑膠袋、牡蠣殼及玻璃碎片等，其中，有機不淨物含量高之河川淤泥，無法直接再利用於CLSM、改質淤泥及取代粒料等工程應用，只能藉由高溫煅燒後製成無機聚合物。本研究將台南地區河川淤泥再利用於製作無機聚合膠結材及混凝土，將其分別加入預成形泡沫，或高分子聚合物進行改質，製成不同相對密度之泡沫無機聚合物，以及不同高分子材料之改質無機聚合物，除考慮大量消耗河川淤泥，同時，增加其製品之高附加經濟價值，因此，藉由試驗量測此兩種河川淤泥無機聚合物之物理及力學性質，評估其再利用於營建材料之可能性。

The chemical and physical properties of river sludge could vary significantly, depending on the location it is evacuated from. River sludge in Taiwan mainly contains clay or sand. In addition, the most waste substances in river sludge are heavy metals, plastic bags, oyster shells and glass fragments, resulting from the pollution of each river. The river sludge with a high organic content cannot be utilized as a construction material for the engineering applications of controlled low strength material (CLSM), organo-modified sludge and aggregate as a replacement of fine aggregate in concrete. It can only be calcined at high temperatures and then reused as a raw material to produce alkali-activated inorganic polymers.
In this study, some river sludge in Tainan was first reused as a raw material to make inorganic polymeric binder and concrete. Furthermore, foamed inorganic polymers with various relative densities and latex-modified inorganic polymers with different introduction of polymeric materials were made from some river sludge, tested mechanically and then compared to each other. As a result, the improvement of mechanical properties and the reduction of manufacturing cost were studied to evaluate the feasibility of using a large amount of river sludge as a raw material in producing inorganic polymeric binders and concrete with good thermal insulation and high energy absorption.
