Method for rapidly preparing mix proportion of recycled aggregate concrete
The invention discloses a method for rapidly preparing a mix proportion of recycled aggregate concrete. The recycled aggregate concrete mix proportion design process comprises the steps of classification of waste concrete in the place, pretreatment of the waste concrete, detection of basic characteristics of recycled aggregate, preliminary screening of mix proportion design according to characteristic conditions, orthogonal test design, mix proportion design and mix proportion application and detection. The workability, the compressive strength and the mix proportion of the recycled concrete with the coarse aggregate substitution rate of 100% are researched through tests, the influence of the water cement ratio, the unit water consumption and the sand ratio on the workability and the compressive strength is emphatically analyzed, and the mix proportion of the recycled aggregate concrete is rapidly and efficiently prepared. The method is suitable for preparing the mix proportion of the recycled aggregate concrete according to different types of waste concrete in various places, and the application range is wide; the recycled aggregate is adopted to completely replace the coarse aggregate in the common material mixing ratio, so that the resource recycling rate is increased; and an orthogonal test design is adopted, so that the mix proportion design is more efficient.
本发明公开了一种快速制备再生骨料混凝土的配合比的方法。再生骨料混凝土配合比设计流程:所在地废弃混凝土分类→废弃混凝土预处理→检测再生骨料基本特性→根据特性情况进行配合比设计初筛→正交试验设计→配合比设计→配合比应用及检测。通过试验对粗骨料取代率为100%的再生混凝土和易性、抗压强度和配合比进行研究,着重分析水灰比、单位用水量和砂率对和易性和抗压强度的影响,快速高效地配制出再生骨料混凝土的配合比。本发明适用于针对各地不同类型废弃混凝土制备再生骨料混凝土的配合比,适用范围广;采用再生骨料100%替换所述普通料配合比中的粗骨料,提高了资源循环利用率;采用正交试验设计,配合比设计更高效。
