Method for constructing cement-stabilized base by using cement tailings as coarse and fine aggregates
The invention belongs to a method for constructing a cement-stabilized gravel base by using cement tailings as coarse and fine aggregates. The method comprises the following steps: batching of a cement-stabilized gravel base, paving of the cement-stabilized gravel base, rolling of the cement-stabilized gravel base, maintenance of the cement-stabilized gravel base and the like. Wherein the particle size ratio of the graded gravel in the cement stabilized gravel lower base layer is (20-31 mm): (10-20 mm): (3-10 mm): (0.075-3 mm) = 18%: 32%: 30%: 20%; wherein the particle size ingredients of the cement tailings respectively account for 6% of 32%, 6% of 30% and 3% of 20% according to the same particle size proportion; the blending proportion of the cement tailings in the cement stabilized base layer replacing the corresponding coarse and fine aggregates in the graded gravel is 15%, the cement tailings and the cement can be used as the stabilized gravel base layer to meet the requirement of excellent quality, and the method has the advantages of simplicity, convenience, practicability, low cost, construction period saving, good quality and long service life.
本发明属于一种用水泥尾矿作粗细集料施工水稳基层的方法，方法包括包括水泥稳定砂砾基层配料、水泥稳定砂砾基层的摊铺、水泥稳定砂砾基层的碾压、水泥稳定砂砾基层的养生等步骤。其中：水泥稳定砂砾下基层中级配砂砾的粒径比例为：20～31mm:10～20mm:3～10mm:0.075～3mm=18%:32%:30%:20%；其中水泥尾矿粒径配料占同粒径比例分别为32%中的6%，30%中的6%，20%中的3%；水泥稳定基层中水泥尾矿代替级配砂砾中对应的粗、细集料的掺配比例为15%，本发明能保证利用水泥尾矿水泥作稳定砂砾基层达到质量优良的要求，具有方法简便实用，成本低,节约工期，质量好和使用寿命长的优点。
