采用正交试验法研究了水灰比、空气含量、硅灰、砂比对混凝土线膨胀系数的影响。结果表明：在一定水泥材料用量下，随着水灰比的增大，混凝土的CLE增大，且水灰比对混凝土CLE的影响显著；随着硅灰掺量的增加，混凝土的CLE增大；当混凝土中空气含量为3.5%时，混凝土的CLE降低，但当混凝土中空气含量为6%时，CLE出现反弹；随着砂率的增加，混凝土的CLE增大；掺硅灰混凝土的单位抗压强度CLE随硅灰掺量的增加而减小；随着空气含量的增加，混凝土的单位抗压强度CLE也随之增加。
The effect of water-cement ratio, air content, silica fume and sand ratio of concrete on the coefficient of linear expansion(CLE) was studied by orthogonal experiment. The results show that under a certain amount of cement material, CLE of concrete increase as the water-cement ratio increases and the effect of water-cement ratio on CLE of concrete is remarkable; with the increase of blending ratio of silica fume, the CLE of concrete increases; the CLE of concrete reduces with 3.5% air content in concrete, but rebound with 6% air content in concrete; with the sand rate increases, CLE of concrete increases; CLE per unit compressive strength of concrete with silica fume decreases with increase of silica fume content; CLE per unit compressive strength of concrete with air content increase when air content increase.
