Preparation method of building solid waste regenerated composite micro powder based on road engineering base
The invention belongs to the field of solid waste utilization, and relates to a preparation method of building solid waste regenerated composite micro powder based on a road engineering base layer, which comprises the following steps: preparing the following raw materials: 76.2-101.6 parts of 42.5-grade P.O, ISO standard sand, 0-25.4 parts of regenerated brick powder, 0-25.4 parts of regenerated concrete powder and 0-348.4 parts of high-calcium fly ash (CaO content is 10%); the mass ratio of cement to fly ash in the cement fly ash stabilized macadam base in certain road engineering is 3.5%: 12%. The report is used for testing the compressive strength and the breaking strength of a regenerated composite micro-powder cement mortar test piece for 3d, 7d and 28d, and analyzing the mechanical property evolution law of regenerated brick powder, regenerated concrete powder and high-calcium fly ash in cement mortar during single doping, double doping and three doping; the optimal proportion of the regenerated composite micropowder (RPBCF) is determined according to comprehensive performance indexes of mortar prepared from different mixing amounts of regenerated brick powder, concrete powder and fly ash. The invention has a huge promotion effect on the development of construction waste resource utilization, and has an important scientific value.
本发明属于固废利用领域，涉及一种基于道路工程基层的建筑固废再生复合微粉的制备方法，包括以下步骤：准备原材料：42.5级P.O 76.2～101.6份，ISO标准砂，再生砖粉0～25.4份，再生混凝土粉0～25.4份，高钙粉煤灰(CaO含量10％)0～348.4份；以某道路工程中水泥粉煤灰稳定碎石基层中水泥:粉煤灰＝3.5％:12％(质量比)。本报告测试再生复合微粉水泥砂浆试件3d、7d、28d抗压、抗折强度，并分析再生砖粉、再生混凝土粉、高钙粉煤灰在水泥砂浆中单掺、两掺、三掺时力学性能演化规律，根据不同掺量再生砖粉、混凝土粉、粉煤灰下所制备的砂浆综合性能指标确定出再生复合微粉(RPBCF)最佳配比。本发明对于建筑垃圾资源利用的发展具有巨大的推进作用，具有重要的科学价值。
