压块密度

Testing of asphalt ; determination of bulk density , compacted density , void content and degree of compaction
沥青的检验.体密度压实密度空隙含量和压缩程度的
The heat conductivity of bentonite will increase with the rising of water content in bentonite under the same compact density
结果表明，在相同的压实密度条件下，随着膨润土含水率的增加，导热系数也增加。
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
本文设计了一套生产再生骨料的处理工艺流程，并利用武昌车辆厂的废弃混凝土制备了一定量的再生骨料。对再生骨料的表观密度、吸水率、压碎指标、容重和孔隙率等基本性能进行了研究，分析了分别采用聚合物和有机硅防水剂进行表面处理后的再生骨料的性能变化。从而得出经过表面处理后再生骨料的吸水率有所降低，性能有所改善。
