The flexural strength could achieve more than 5.5MPa at 28 days, and the recycled concrete felt with the existent pavement well, which could fulfill the long-term requirements of airfield pavement, the concrete also could be used in the rapid repair the cement concrete pavement of civil airfield and highway. 1 Introduction Cement concrete has excellent construction properties and durability[1], it constitutes the mostly building material of airfield pavement.
At present, the repair materials for the pavement include very quickly setting cement concrete, Portland cement concrete with flash admixture, mineral or organic polymer concrete, and so on, but there are some questions, such as the 4 hours’ strength is lower, the felting performance of repair materials and the existent pavement is not definite, the long-term strength is lower and even minish[2~3].
The tiny aggregates effect could stoppage the bleeding channels in the mortar and prevent the concrete from segregating and bleeding, so the concrete has well capability of water retention[8]. 3 Test studies 3.1 Materials (1)Cement: a, 42.5R portland cement was produced in Yaoxian of Shaanxi, the density is 3.10g/cm3, the flexural strength and compressive strength at 3 days are 6.1MPa and 28MPa, at 28 days are 8.9MPa and 48MPa; b, Type S early strength special cement was produced by Double-crane Special Cement Limited Company of Shanghai, the density is 3.10g/cm3, the initial setting time≤5 minutes, the final setting time≤10 minutes, when W/C=0.35, the compressive strength of neat cement grout at 2 hours is higher than 20MPa, at 1 day is higher than 40MPa; (2)Fly ash: Fly ash of grade Ⅱ was produced by Wei River Power Plant in Shaanxi, the density is 2.20g/cm3, the water requirements ratio is 91%; (3)Fine aggregate: Medium sand from Ba River in Shaanxi, the fineness module is 2.73
