The invention discloses a prestressed dry and hard recycled concrete laminated slab and a manufacturing process thereof, and belongs to the field of building material manufacturing, the prestressed dry and hard recycled concrete laminated slab comprises a recycled concrete prefabricated layer, side panel grooves are formed in the two ends of the recycled concrete prefabricated layer respectively, and a protective layer is laid at the bottom end of the recycled concrete prefabricated layer; prestressed steel strands are embedded in the recycled concrete prefabricated layer, transverse steel bars are laid at the upper end of the recycled concrete prefabricated layer, longitudinal steel bars are laid at the upper end of the recycled concrete prefabricated layer, and a concrete post-pouring layer is poured at the upper end of the recycled concrete prefabricated layer. According to the method, the laminated slab can be manufactured very conveniently and rapidly, steam curing does not need to be conducted on the formwork additionally, the water content is small, concrete is in a contracted state, the strength is high, and the construction cost of constructional engineering is reduced.
本发明公开了一种预应力干硬性再生混凝土叠合板及其制作工艺，属于建筑材料制作领域，包括再生混凝土预制层，所述再生混凝土预制层两端分别开设有侧面板槽，所述再生混凝土预制层底端铺设有保护层，所述再生混凝土预制层内部镶嵌有预应力钢绞线，所述再生混凝土预制层上端铺设有横向钢筋，所述再生混凝土预制层上端铺设有纵向钢筋，所述再生混凝土预制层上端浇筑有混凝土后浇层；本发明能够非常方便、快捷地制作叠合板，不用另外对模板进行蒸汽养护，其中含有的水量比较少，混凝土呈现收缩状态，强度较高，降低降低建筑工程的造价。
