EXPERIMENTAL STUDY ON FLEXURAL PROPERTIES OF RECYCLED MICRONIZED CONCRETE LAMINATED SLABS
In order to realize the resource utilization of construction solid waste,this paper prepares recycled ce-ment paste powder (RSP) and recycled brick powder (RBP) as cementitious materials to produce laminated panels,in order to study the effect of different micropowders on the bending performance of concrete laminated panels. The results show that the bending damage process of RSP laminated slabs is basically the same as that of ordinary con-crete laminated slabs,but the cracking load,yield load and ultimate load are different;when RSP replaces cement,the ultimate load will be reduced to a certain extent,and different RSPs have different influences on the ultimate load of the slabs;the maximum reduction of the ultimate load is 16.5％,and the minimum reduction is 10.6％,com-pared with that of ordinary slabs;the maximum reduction is 10.6％. The maximum reduction in ultimate load is 16.5％and the minimum is 10.6％;however,when recycled micronized powder replaces fly ash,the reduction in ulti-mate load is not obvious,and the reduction in ultimate load is only 3.6％ when compared with the ordinary plate. Therefore,this study can provide an experimental basis for the application of recycled micronized powder in laminat-ed panels.
