摘要：对比研究了相同配合比条件下，机制砂和天然砂对C35混凝土的力学性能及体积变形的影响。结果表明：机制砂混凝土的力学性能明显优于天然砂混凝土；180 d时，机制砂混凝土的抗压强度较天然砂混凝土提高了15.3%，劈裂抗拉强度提高了4.3%；90 d时，机制砂混凝土的静弹性模量较天然砂混凝土提高了5.8%；机制砂混凝土的体积变形明显大于天然砂混凝土，180 d时，机制砂混凝土较天然砂混凝土的自收缩增大了约16.4%；机制砂中石粉掺量不宜过大，否则会显著增大混凝土的收缩开裂。 Abstract: The effects of mechanism sand and natural sand on the mechanical properties and volume deformation of C35 concrete under the same mix proportion conditions were studied. The results show that the mechanical properties of manufactured sand concrete are significantly better than those of natural sand concrete. At 180 d, the compressive strength of manufactured sand concrete increases by 15.3% compared to natural sand concrete, and the splitting tensile strength increases by 4.3%. At 90 d, the static elastic modulus of manufactured sand concrete increases by 5.8% compared to natural sand concrete. The volume deformation of manufactured sand concrete is significantly greater than that of natural sand concrete. At 180 d, the self-shrinkage of manufactured sand concrete increases by about 16.4% compared to natural sand concrete. The content of stone powder in the manufactured sand should not be too large, otherwise it will significantly increase the shrinkage and cracking of concrete.

Abstract: The effects of mechanism sand and natural sand on the mechanical properties and volume deformation of C35 concrete under the same mix proportion conditions were studied. The results show that the mechanical properties of manufactured sand concrete are significantly better than those of natural sand concrete. At 180 d, the compressive strength of manufactured sand concrete increases by 15.3% compared to natural sand concrete, and the splitting tensile strength increases by 4.3%. At 90 d, the static elastic modulus of manufactured sand concrete increases by 5.8% compared to natural sand concrete. The volume deformation of manufactured sand concrete is significantly greater than that of natural sand concrete. At 180 d, the self-shrinkage of manufactured sand concrete increases by about 16.4% compared to natural sand concrete. The content of stone powder in the manufactured sand should not be too large, otherwise it will significantly increase the shrinkage and cracking of concrete.
