Method for preparing foam concrete by using construction waste recycled aggregate
The invention discloses a method for preparing foam concrete by using construction waste recycled aggregate. The foam concrete is prepared from the following raw materials in parts by weight: 50-55 parts of construction waste recycled aggregate, 25-30 parts of Portland cement, 8-15 parts of ceramic fiber, 4-8 parts of pyrite cinder, 45-55 parts of water, 8-10 parts of a polycarboxylic acid water reducer, 3-5 parts of cellulose ether, 2-3 parts of a shrinkage reducing agent and 5-6 parts of a foaming agent. The construction waste recycled fine aggregate is used for replacing natural sand in a traditional foam concrete preparation method, the physical and mechanical properties of the construction waste recycled fine aggregate are enhanced by adding the mixed admixture, and the quality and preparation efficiency of the foam concrete are improved by adopting a steam curing method. The problems that foam concrete is low in strength, easy to shrink and crack and poor in stability are solved.
本发明公开了一种利用建筑垃圾再生骨料制备泡沫混凝土的方法。所述泡沫混凝土由以下重量份的原料制备而成：建筑垃圾再生骨料50~55份、硅酸盐水泥25~30份、陶瓷纤维8‑15份、硫铁矿烧渣4~8份、水45~55份、聚羧酸系减水剂8‑10份、纤维素醚3‑5份、减缩剂2~3份、发泡剂5~6份。本发明利用建筑垃圾再生细骨料代替传统泡沫混凝土制备方法中的天然砂，添加混合掺料来强化建筑垃圾再生细骨料的物理力学性能，并采取蒸汽养护的方法提高泡沫混凝土的质量与制备效率，本发明解决了泡沫混凝土强度低、易收缩干裂和稳定性差的问题。
