Solid waste composite foam concrete and preparation method thereof
The invention relates to the field of building materials, in particular to solid waste composite foam concrete and a preparation method thereof.The solid waste composite foam concrete is prepared from, by weight, 200-300 parts of cement, 100-200 parts of residual concrete slurry, 200-250 parts of recycled aggregate, 8-45 parts of mirabilite, 15-30 parts of water reducing agent, 15-20 parts of foaming agent and 90-120 parts of water. According to the solid waste composite foam concrete provided by the invention, by doping mirabilite, the early hydration process of the foam concrete is accelerated and propelled, so that the foam concrete with low cement consumption can obtain relatively high compressive strength; according to the method, the compressive strength of the foam concrete is improved, so that the residual concrete slurry and the recycled aggregate are compounded, and the solid waste resources are recycled.
本发明涉及建筑材料领域，特别涉及一种固废复合泡沫混凝土及其制备方法，固废复合泡沫混凝土按重量份计，包括以下原料：水泥200‑300份、混凝土余浆100‑200份、再生骨料200‑250份、芒硝8‑45份、减水剂15‑30份、发泡剂15‑20份、水90‑120份。本发明提供的固废复合泡沫混凝土通过掺入芒硝，加速、推进了泡沫混凝土的早期水化进程，使水泥用量低的泡沫混凝土能够获得较高的抗压强度；由于该方法使泡沫混凝土抗压强度的提高，得以复合混凝土余浆和再生骨料，从而将这些固废资源进行回收利用。
