Testing of asphalt ; determination of bulk density , compacted density , void content and degree of compaction
瀝青的檢驗.體密度壓實密度空隙含量和壓縮程度的
The heat conductivity of bentonite will increase with the rising of water content in bentonite under the same compact density
結果表明，在相同的壓實密度條件下，隨著膨潤土含水率的增加，導熱系數也增加。
The paper designs a set of technics flow of producing recycled aggregates and uses scrap concrete in wuchang vehicle factory to manufacture some recycled aggregates , and researches the basic properties of recycled aggregates such as apparent density , absorption , crush index , compacted density , porosity , etc . and analyses the properties change of recycled aggregates after the respective surface treatment with the polymer and polysilicone waterproofing agents , and then obtains the result that their absorption decreases and their properties improves after recycled aggregates are surface treated
本文設計了一套生產再生骨料的處理工藝流程，并利用武昌車輛廠的廢棄混凝土制備了一定量的再生骨料。對再生骨料的表觀密度、吸水率、壓碎指標、容重和孔隙率等基本性能進行了研究，分析了分別采用聚合物和有機硅防水劑進行表面處理后的再生骨料的性能變化。從而得出經過表面處理后再生骨料的吸水率有所降低，性能有所改善。
