再生砖混骨料的研究现状与应用探讨

随着我国城市建设速度的加快,大量建筑废弃物无处堆放且难以得到有效地利用。将建筑废弃物破碎筛分成砖混骨料不仅可以大幅降低工程造价,另一方面也缓解建筑废弃物处置,砂石资源短缺等问题。因此该文针对再生砖混骨料的研究现状展开探讨,总结砖混骨料的材性指标,水稳材料强度形成机理以及混凝土与水泥稳定材料掺入砖混骨料后力学性能及耐久性能的变化规律。为今后砖混骨料广泛应用于实际工程提供参考。

With the acceleration of urban construction in China,a large number of construction wastes have nowhere to be piled up and are difficult to be used effectively.The crushing and screening of construction waste into brick-concrete aggregate can not only greatly reduce the project cost,but also alleviate the problems such as the disposal of construction waste and the shortage of sand and gravel resources.Therefore,this paper discusses the research status of recycled brick aggregate,and summarizes the material property index of brick aggregate,the strength formation mechanism of water stabilized materials and the change law of mechanical properties and durability of concrete and cement stabilized materials mixed with brick aggregate,thereby provides a reference for the wide application of brick-concrete aggregate in practical engineering in the future.
