Construction waste pervious concrete mix proportion design method
The invention discloses a construction waste pervious concrete mix proportion design method, aggregate adopts two-grade graded construction waste of 4.75-9.5 mm and 1.18-2.36 mm, green, low-carbon, energy-saving and environment-friendly construction is realized, meanwhile, the contact surface between the aggregate is effectively increased, a continuous slurry bridge is favorably formed by a cement cementing material, the strength of pervious concrete is further greatly improved, and the service life of the pervious concrete is prolonged. According to the present invention, by using the gap-graded two-grade construction waste as the aggregate, the interference effect between the aggregates is reduced while the pervious concrete skeleton is formed, the skeleton stability is easily achieved, the segregation phenomenon caused by the large particle size difference is reduced, and the site construction operation is easily achieved. According to the method, the coordination between the strength of the pervious concrete and the working performance is synthesized, construction conducted at the cost of performance loss in the construction operation process can be effectively reduced, solid waste recycling is achieved, meanwhile, the construction quality is effectively guaranteed, and remarkable social and economic benefits are achieved.
本发明公开了一种建筑垃圾透水混凝土配合比设计方法，骨料采用4.75～9.5mm、1.18～2.36mm两档断级配建筑垃圾，在实现绿色低碳、节能环保建设，同时有效增大集料之间接触面，利于水泥胶凝材料形成连续的浆桥，进而大大提升透水混凝土强度，利用断级配的两档建筑垃圾作为骨料，在形成透水混凝土骨架的同时，减少骨料之间的干涉作用，利于骨架稳定性，同时减少因粒径差异过大带来的离析现象，利于现场施工作业。该方法综合透水混凝土强度与工作性能之间的协调性，能有效减少施工作业过程中出现以一种性能的损失为代价而进行的施工，再实现固废循环再利用同时，有效保证了施工质量，具有显著的社会经济效益。
