摘要
混凝土开裂是影响路面混凝土耐久性的重要因素,粉煤灰混凝土具有较好的综合耐久性。通过对不同粉煤灰掺量混凝土在不同养护条件下开裂性的试验研究,验证了粉煤灰对混凝土抗裂性的影响。
Cracking is an important factor influencing the durability of concrete pavement, while fly - ash concrete is of better comprehensive durability. Based on the trial study of crack resistance with different dosages of admixing fly - ash under all curing conditions, this article analyzes effect of fly - ash on the crack resistance of road concrete.
