The Sand Applicability Of The Mechanism In The Concrete Structural Thing To Study

Traffic basic development at full speed of construction of facilities, result in, build the road material fast soaring of consumption, it is most high-level to make the grit material reach at quality and competence of using in history. Meanwhile, because of the resource maldistribution of sand of our country, the sand for building is about more than 3 billion tons every year, the consumption is very enormous, the contradiction causing sand resources in short seems outstanding day by day. The more and more one regards sand of mechanism as the substituting materials of the river sand now, the progressively extensive ground is applied to various project buildings. This text combines the requirement for wide Palestinian expressway engineering construction of Sichuan Province, on the basis of making investigations and the theory is analyzed, to the characteristic of the sand of mechanism, use and design the testing program to carry on both sand and river sand of mechanism to fully compare with research evenly, through certain using the means and improving the measure, solve the contradiction between the mechanics performance of physics and working, have made some research results.Utilize the research results to make the sand of mechanism totally substitute or substitute the river sand and formulate out the concrete partly, apply to project reality, has overcome the existing bad shortcoming of sand of mechanism. Relieve the tense situation of supply and demand of material, in order to save the fabrication cost of the project, protect the environment, promoting the quality of the road has certain social effect and project value.
