The invention relates to a preparation method of a single-component geopolymer straw aggregate, which comprises the following steps: crushing straw particles, spraying and wetting the straw particles with water, spraying and mixing the straw particles and sodium hydroxide particles, stirring and mixing the straw particles and sodium silicate particles, vibrating, extruding and compacting the straw mixture to form a straw aggregate block, and drying the straw aggregate block to obtain the single-component geopolymer straw aggregate. Sealing and packing the straw aggregate blocks by adopting a polyethylene film and a packing belt; the straw aggregate block is used as a carrier of an alkaline activator, so that the problems of corrosion danger caused by adding the activator into a traditional geopolymer composite material at a construction site and inaccurate field proportioning and metering error of a single-component geopolymer are solved, time and labor are saved, and the problems of looseness, large unit volume and low cost of a straw material are solved. And loading, unloading and transportation costs are high.
一种单组分地质聚合物秸秆集料的制备方法，其制作工艺包括秸秆颗粒粉碎，秸秆颗粒洒水喷淋润湿，秸秆颗粒与氢氧化钠颗粒喷洒混合，秸秆颗粒与硅酸钠颗粒搅拌混合，秸秆混合料振捣挤压密实成型为秸秆集料块体，采用聚乙烯薄膜及打包带密封打包秸秆集料块体；秸秆集料块体作为碱性激发剂的载体，解决了传统地质聚合物复合材料在施工现场添加激发剂引发的腐蚀危险，解决了单组分地质聚合物现场配比不精准，计量误差的问题，省时省力，解决了秸秆材料松散，单位体积大，装卸及运输成本高的问题。
