Mix proportion design method and application of recycled brick-concrete pervious concrete
The invention discloses a mix proportion design method and application of recycled brick-concrete pervious concrete, and the method comprises the following steps: presetting a target porosity, a testwater cement ratio, a cement aggregate ratio and a sand rate, selecting a recycled aggregate replacement rate, a fly ash replacement rate and a theoretical mixing amount of a water reducing agent, calculating the consumption of recycled and natural aggregates in each cubic meter of recycled brick pervious concrete, calculating the volume of the cementing material slurry in each cubic meter of therecycled brick pervious concrete and the dosage of cement, theoretical water, fly ash and a water reducing agent, calculating the actual water consumption in each cubic meter of recycled brick pervious concrete, calculating the use amount of sand in each cubic meter of recycled brick pervious concrete, and determining a final mixture ratio. According to the mix proportion design method, recycled brick-concrete aggregate is considered to be doped, and reference and guidance are provided for use of low-quality recycled aggregate, meanwhile, the method is simple, the quality is easy to control, the cement consumption can be reduced under the condition of considering the target porosity, environmental protection is facilitated, and the resource utilization rate is increased.
本发明公开了一种再生砖混透水混凝土的配合比设计方法及其应用，该方法其包括以下步骤：预设目标孔隙率、试验水灰比、水泥骨料比和砂率，并选取再生骨料取代率、粉煤灰置换率和减水剂理论掺量；计算每立方米再生砖混透水混凝土中再生、天然骨料的用量；计算每立方米再生砖混透水混凝土中胶凝材料浆体的体积、水泥、理论用水、粉煤灰、减水剂的用量；计算每立方米再生砖混透水混凝土中实际用水量；计算每立方米再生砖混透水混凝土中砂用量；确定最终配合比。该配合比设计方法考虑掺入再生砖混骨料，为低品质的再生骨料使用提供借鉴与指导；同时，该方法简单且质量易控，在考虑目标孔隙率情况下可降低水泥用量，有利于环保并提高资源化利用率。
