Recycled GFRP powder/slag-based geopolymer cured clay and preparation method thereof
The invention discloses recycled GFRP (glass fiber reinforced plastic) powder/slag-based geopolymer cured clay and a preparation method thereof, the recycled GFRP powder/slag-based geopolymer cured clay is prepared from the following substances in parts by weight: 20-40 parts of recycled GFRP powder, 60-80 parts of slag, 70-80 parts of clay and 100-200 parts of aqueous alkali, and the concentration of the aqueous alkali is 8.7-10.2 M; the modulus of the aqueous alkali is 1.2; the liquid-solid ratio is 1.0 to 1.4. The alkali-activated activity of aluminosilicate fibers can be utilized, the characteristic that slag geopolymer solidified soil is prone to cracking is improved, and the defects that a traditional cement-based soil solidifying agent is large in dry shrinkage, prone to cracking and poor in water stability are overcome. The recycled GFRP powder does not need to be subjected to fiber and resin separation, the GFRP powder and slag generate gel under the action of alkali excitation, the gel replaces a cement-based material to serve as a soil curing agent, the problems that in the cement production process, energy consumption is large, and a large amount of CO2 is discharged can be effectively solved, and remarkable economic, environment-friendly and social benefits are achieved.
本发明公开了一种回收GFRP粉末/矿渣基地聚物固化黏土及制备方法，包括以下重量份的物质组成：回收GFRP粉末20份～40份，矿渣60份～80份，黏土70份～80份，碱溶液100份～200份，其中碱溶液浓度为8.7M～10.2M；碱溶液模数为1.2；液固比：1.0～1.4。本发能利用硅铝酸盐系纤维的碱激发活性，改善矿渣地聚物固化土易产生裂纹的特点，弥补传统水泥基土壤固化剂干缩大、易开裂、水稳性较差的特点。回收GFRP粉末无需进行纤维和树脂分离，与矿渣在碱激发作用下生成胶凝体，替代水泥基材料作为土壤固化剂，可有效缓解水泥在生产过程中能耗大，排放大量CO2等问题，具有显著的经济、环保与社会效益。
