摘要
采用粉煤灰、硅灰及钢纤维、聚丙烯纤维配制机制砂机场道面混凝土,通过单掺及复掺的方式,研究了不同掺量、不同配合比对机场道面混凝土力学性能、耐磨性能、抗冲击性能、抗冻性能的影响。结果表明,采用硅灰、粉煤灰与钢纤维、聚丙烯纤维复合的方式,在钢纤维、聚丙烯掺量分别为7.9kg/m^3和1.5kg/m^3的情况下,可配制出超高力学性能及优异耐久性能的道面混凝土。
The mechanism sand airport pavement concrete is prepared with fly ash,silica fume, steel fibers and polypropylene fiber. The effects of different dosage and different coordination on the mechanical properties, abrasion resistance, impact resistance and frost resistance of airport pavement were studied by means of single mixing and blending. The results show that in the case of steel fiber polypropylene content of 7.9kg/m^3 and 1.5kg/m^3 respectively, high mechanical properties and excellent durability pavement concrete can be prepared by using silica fume, fly ash, steel fiber and polypropylene fiber compasite.
