摘要
混凝土的耐久性是衡量水泥混凝土公路长期工作性能的重要指标,通过相关标准试验,对不同水灰比和不同粉煤灰掺率下的混凝土进行了相关试验,通过对试验数据的整理可见,在冻融循环作用下,水灰比过大和粉煤灰掺率过小都会导致混凝土内部的毛细孔数量变多,使得混凝土的抗渗性能和抗冻性能降低,影响到水泥混凝土公路的路用性能。
Durability of concrete is an important indicator of long-term performance of cement concrete roads,the article through the relevant standard tests of concrete mixed with fly ash at different water and different rates under the relevant test conducted by the test data finishing,seen in the freezing and thawing cycles,water-cement ratio is too large and too small fly ash mixing ratio will result in the number of pores inside the concrete increases,so impermeability and frost resistance of concrete to reduce the impact to the concrete Highway road performance.
