Recycled concrete veneer and preparation method thereof
The invention relates to the technical field of recycled veneers, in particular to a recycled concrete veneer and a preparation method thereof. The recycled concrete veneer is prepared from the following preparation raw materials in parts by weight: 1 part of cement, 0.05 to 0.20 part of fly ash, 0.08 to 0.2 part of mineral powder, 0.03 to 0.08 part of silica fume, 2.0 to 4.5 parts of recycled fine aggregate, 1.0 to 3.5 parts of recycled coarse aggregate, 0.01 to 0.035 part of water reducing agent, 0.01 to 0.04 part of shrinkage reducing agent, 0.01 to 0.03 part of defoaming agent and 0.48 to 0.64 part of water. The particle size of the recycled fine aggregate is smaller than that of the recycled coarse aggregate; and the recycled fine aggregate and the recycled coarse aggregate are prepared from building (structure) waste. By means of the recycled concrete veneer, reutilization of construction waste is achieved, and the purposes of energy conservation, environmental protection, harmlessness and recycling are achieved.
本发明涉及再生饰面板技术领域，尤其涉及一种再生混凝土饰面板及其制备方法。本发明提供了一种再生混凝土饰面板，按重量份计，包括以下制备原料：水泥1份，粉煤灰0.05～0.20份，矿粉0.08～0.2份，硅灰0.03～0.08份，再生细骨料2.0～4.5份，再生粗骨料1.0～3.5份，减水剂0.01～0.035份，减缩剂0.01～0.04份，消泡剂0.01～0.03份和水0.48～0.64份；所述再生细骨料的粒径小于所述再生粗骨料的粒径；所述再生细骨料和再生粗骨料由建(构)筑废弃物制备得到。本发明所述的再生混凝土饰面板实现了对建筑垃圾的再利用，实现了节能、环保、无害化和资源化的目的。
