高抗冻碾压混凝土胶砂裹石拌和方法
摘要：
本发明涉及一种高抗冻碾压混凝土胶砂裹石拌和方法，适用于寒区高抗冻碾压混凝土施工领域。采用的胶砂裹石拌和方法是：采用强制式搅拌机分段拌和，拌和时先投入胶凝材料、砂料，加外加剂水溶液搅拌2min~3min，再加入石料搅拌1.5min~3.0min。本发明明显提高了碾压混凝土含气量，可广泛应用于常态混凝土拌和工艺中，具有广泛的推广应用价值。
摘要（英）：

The invention relates to a high frost resistance roller compacted concrete mortar wrapped stone mixing method which is suitable for the field of construction of high frost resistance roller compacted concrete in a cold region. The high frost resistance roller compacted concrete mortar wrapped stone mixing method comprises the steps of: stirring by sections by adopting a forced stirring machine, firstly putting a binding material and a sand material during stirring, adding an additive water solution for stirring for 2min-3min, and then adding stone for stirring for 1.5min-3.0min. The method provided by the invention remarkably increases the gas content of roller compacted concrete, can be widely applied to a normal concrete mixing process, and has wide popularization and application values.
