Light high-strength fabricated board based on waste gypsum board and preparation method thereof
The invention discloses a light-weight high-strength fabricated board based on a waste gypsum board. The light-weight high-strength fabricated board comprises the following components in parts by weight: 100 parts of regenerated alpha-type semi-hydrated gypsum powder, 20-30 parts of fly ash, 5-10 parts of cement, 8-15 parts of EPS light aggregate and 50-55 parts of water. The regenerated alpha-type semi-hydrated gypsum powder is formed by performing activation pretreatment and secondary crystal form conversion treatment on waste gypsum boards. The regenerated alpha-type semi-hydrated gypsum powder obtained by the invention has the characteristics of low standard thickening water demand and high strength, and can be matched with fly ash and cement to further improve the later strength of ahardened body, so as to prepare an assembled plate which can effectively consider the advantages of light weight, high strength and low cost; and the related preparation method is simple, can realizehigh-added-value utilization of the waste gypsum board, and has important economic and environmental benefits.
本发明公开了一种基于废弃石膏板的轻质高强装配式板材，各组分及其所占重量份数包括：再生α型半水石膏粉100份，粉煤灰20～30份，水泥5～10份，EPS轻集料8～15份，水50～55份；所述再生α型半水石膏粉为废弃石膏板经活化预处理和二次晶型转化处理而成。本发明所得再生α型半水石膏粉料具有低标稠需水量和高强度特性，与粉煤灰、水泥配合作用可进一步提升硬化体的后期强度，以制备得到可有效兼顾轻质、高强和低成本优势的装配式板材；且涉及的制备方法简单，并可实现废弃石膏板的高附加值利用，具有重要的经济和环境效益。
