Regenerated plastic-based high-strength foam concrete and preparation method thereof
The invention relates to an efficient utilization method of regenerated plastic, in particular to regenerated plastic-based high-strength foam concrete which comprises the following components in parts by weight: 100 parts of cement, 15-32 parts of fly ash, 35-70 parts of regenerated plastic, 5-15 parts of carbon fiber chopped strands, 1-3 parts of a foaming agent, 2-4 parts of a water reducing agent, 3-6 parts of a silane coupling agent and 10-30 parts of water. The regenerated plastic is modified PP regenerated plastic, and particularly, calcium carbonate is adopted to carry out filling modification on PP. The regenerated PP plastic particle structure obtained after inorganic filler modification contains a large amount of calcium carbonate particles, the particles have good compatibility with cement, fly ash and other components, and the binding strength between interfaces is improved; on the other hand, the strength of the PP modified by the inorganic filler is also increased, and the strength of the concrete prepared from the PP is further enhanced.
本发明涉及一种再生塑料的高效利用方法，具体涉及一种基于再生塑料的高强度泡沫混凝土，包括如下重量份数的组成：水泥100份、粉煤灰15‑32份、再生塑料35‑70份、碳纤维短切丝5‑15份、发泡剂1‑3份、减水剂2‑4份、硅烷偶联剂3‑6份、水10‑30份；所述再生塑料为改性PP再生塑料，具体是采用碳酸钙对PP进行填充改性；这种通过无机填料改性后得到的再生PP塑料颗粒结构中含有大量得碳酸钙颗粒，这些颗粒与水泥、粉煤灰等其他组分得相容性较好，增加了界面之间得粘接强度；另一方面，通过无机填料改性后的PP本身的强度也增加了，当其制成混凝土后的强度进一步增强。
