Mix proportion design method of recycled all-light concrete
The invention provides a mix proportion design method of recycled all-light concrete, and belongs to the field of building materials. The design method comprises the following steps: (1) determining the water-binder ratio and the unilateral initial dosage of each raw material in the neat paste; (2) screening the regenerated light material, and determining the primary clear distance of the regenerated light material according to the mass of screen residues with different particle sizes; (3) determining the unit dosage of the regenerated light material and the net slurry according to the primaryclear distance; and converting the preliminarily determined dosage of each raw material into a preliminary reference mix proportion; (4) performing trial mixing optimization on the preliminary reference mix proportion to obtain a reference mix proportion; and (5) detecting raw material indexes for production adjustment, and converting the reference mix proportion into a production mix proportion.By means of the method, the reasonable use of the regenerated powder and the regenerated light material in the regenerated full-light concrete is realized, the internal stress balance is met, and theworkability and the cost performance are both considered.
本发明提供了一种再生全轻砼的配合比设计方法，属于建筑材料领域。该设计方法包括：(1)确定水胶比及净浆体中各原料的单方初定用量；(2)对再生轻料进行筛分，根据不同粒径的筛余质量，确定再生轻料的初级净距；(3)根据初级净距确定再生轻料和净浆体的单方用量；根据各原料的初定用量换算成初步基准配合比；(4)对初步基准配合比进行试拌优化，得到基准配合比；(5)检测用于生产调整的原料指标，将基准配合比换算为生产配合比。本发明采用上述方法实现了再生粉料和再生轻料在再生全轻砼中的合理使用，既满足内部受力平衡，又兼顾工作性和性价比。
