Plateau region airport pavement concrete and preparation method thereof
The invention belongs to the technical field of concrete materials, and particularly relates to plateau region airport pavement concrete and a preparation method thereof. The plateau region airport pavement concrete is prepared from the following raw materials in parts by weight: 330-450 parts of cement; 1000 to 1200 parts of coarse aggregate; 550 to 650 parts of fine aggregate; 60 to 90 parts of fly ash; 2.1-3 parts of a water reducing agent; 15-20 parts of an early strength agent; 0.03 to 0.05 part of an air entraining agent; 0.6 to 0.8 part of super absorbent resin; 4-6 parts of composite fiber; and 137-190 parts of water. The invention designs and prepares the concrete capable of overcoming the cracking problem caused by the plateau dry environment, and applies the concrete to airport pavements in plateau areas.
本发明属于混凝土材料技术领域，具体涉及一种高原地区机场道面混凝土及其制备方法。高原地区机场道面混凝土由如下重量份数的原料制成：水泥330‑450份；粗骨料1000‑1200份；细骨料550‑650份；粉煤灰60‑90份；减水剂2.1‑3份；早强剂15‑20份；引气剂0.03‑0.05份；高吸水性树脂0.6‑0.8份；复合纤维4‑6份；水137‑190份。本发明设计并制备一种克服高原干燥环境引起开裂问题的混凝土，并将其应用于高原地区机场道面。
