摘　　要：机制山砂是岩石经专门机械破碎筛分制成的山砂,其混凝土除耐磨性较差外,与钢筋粘结力、弹性模量、抗折和抗压强度等均接近中、粗河砂混凝土。在不久的将来,机制山砂因制造方便,性能优良,将在建筑行业得到普及。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.
