The invention discloses a concrete heat preservation wallboard based on construction waste, and relates to the technical field of concrete heat preservation wall preparation, the concrete heat preservation wallboard comprises a concrete wallboard base plate, polyurethane foam glue and a polyurethane foam plate, an adhesion agent is arranged on the outer side of the concrete wallboard base plate, the polyurethane foam glue is arranged on the outer side of the adhesion agent, and the polyurethane foam plate is arranged on the outer side of the adhesion agent. The polyurethane foam board is arranged on the outer side of the concrete wallboard base board through polyurethane foam glue. The shape of the recycled coarse aggregate is improved through a physical modification method, and the use performance of the recycled coarse aggregate in concrete is improved, so that the void ratio in the concrete is reduced, and the compactness and compressive strength of the concrete are improved; ultrasonic waves generate high-frequency vibration and a cavitation effect, so that the organosilicon waterproofing agent is uniformly dispersed and reacts with components in the aggregate to generate a product to fill pores of the recycled coarse aggregate, microcracks generated by crushing on the surface of the aggregate are repaired and filled, the pore structure in the aggregate is improved, and the compactness of the aggregate is improved, so that the void ratio is reduced.
本发明公开了一种基于建筑垃圾的混凝土保温墙板，涉及混凝土保温墙体制备技术领域，包括混凝土墙板基板、聚氨酯泡沫胶和聚氨酯泡沫板，所述混凝土墙板基板的外侧设置有界面剂，所述界面剂的外侧设置有聚氨酯泡沫胶，所述聚氨酯泡沫板通过聚氨酯泡沫胶设置在混凝土墙板基板的外侧。本发明通过物理改性方法改善再生粗骨料的形状，提高其在混凝土中的使用性能，从而减少混凝土内空隙率，提高混凝土的密实性和抗压强度，超声波产生高频振动和空化效应使有机硅防水剂均匀分散并与骨料中的成分反应产生生成物对再生粗骨料的孔隙进行填充，修复填充骨料表面由于破碎产生的微裂缝，改善骨料内部的孔结构，提高骨料的密实程度从而降低空隙率。
