Research Of Experimental Method In The Mechanical Properties Of Coarse Aggregate

Coarse aggregate is granular material.Research of mechanical properties in granular material is based on the continue media theory for long years,but in fact not scientific.Yet we should study granular mechanical properties based on the granular media theory by contact areas.Recently national micromechanics theory of granular material may deeply help to study the mechanical properties in granular material.On the same time, experiment in engineering can only test weared stone value ,not derectly test the mechanical properties of coarse aggregate now.On one hand,we made the testing method of elastic parameter in coarse aggregate based on the micromechanical model.First ,the basic method of testing the elastic parameter in coarse aggregate is made and the number of contact areas in coarse aggregate is solved.Testing the elastic parameter of coarse aggregate by micromechanical method is performed finally.On the other hand,because now in engineering men can only test the weared stone value,to develop the method of it is foundmental by the need of engineering recently.We develop the testing method of weared stone value by realize virtual instrument of testing weared stone value based on LabVIEW,and offer a new idea and continent method for experiment of mechanical properties in coarse aggregate.
