几个与“密度”关联概念的理解与应用研究

The research of understanding and application to the several concepts associated with the "density"

有关"密度"的物理参数、概念有:表观密度、真密度、视密度、堆积密度、松散堆积密度、紧密堆积密度、干密度、湿密度、比重、容重等,本文从定义、理解与应用方面进行了研究,正确把握它们之间的区别与联系,在混凝土行业及其它行业更好的指导生产,控制质量。

Relevant 'density' physical parameters,concepts: apparent density,true density,depending on the density,bulk density,loose closely bulk density and stacking density,dry density,wet density,proportion,density and so on,the definition,understanding and application are studied,correctly grasp the differences and relations among them in order to guide produciton and control quality of concrete and other industries.
