本文通过对建筑垃圾再生粉料的基本性能、胶砂流动度和胶砂强度等性能的试验研究,得出结论:建筑垃圾再生粉料有一定的活性,其各项性能指标满足II级粉煤灰要求,因此可作为混凝土矿物掺合料使用,配制混凝土。通过胶砂试验表明,再生粉料的掺量应控制在20%以下,才能保证各种性能不受影响;超过20%,其性能随掺量的增加急剧下降,进而可能影响到混凝土的性能,因此再生粉料的掺量要控制在一定范围内使用,才能发挥良好的活性特征。
Based on the experimental study on the basic performance of building waste recycle powder, the fluidity of mortar and the strength of mortar, the conclusion is drawn that the recycle powder of construction waste has certain activity, and its performance indexes meet Grade II pulverized coal Ash requirements, it can be used as a concrete mineral admixture, the preparation of concrete. Through the mortar test, the content of recycled powder should be controlled below 20% to ensure that all kinds of properties will not be affected. When the content exceeds 20%, the properties will decline sharply with the increase of dosage, which may affect the properties of concrete, Therefore, the content of recycled powder to be controlled within a certain range of use, to play a good active characteristics.
