| Abstract: | Mechanism mountain sand is the mountain rocks crushed and screened by the special mechanical. In addition to the poor abrasive resistance, the concrete is close to the coarse river sand concrete reflected in the steel cohesive force, elastic modulus, flexural and compressive strength. In the near future, mechanism mountain sand will be gained popularity in the construction industry because of easy fabrication and good performance. |
