以煤矸石为原材料,添加相应发泡剂和胶凝剂制备产品。制备完成后进行性能测试。在煤矸石多孔土壤制备研制过程中,采用单因素实验方法,先探究不同温度下煅烧活化效果,之后探究发泡剂种类和胶凝剂种类对多孔土壤性能的影响,制定吸水材料的最佳配料种类。结果表明:以山西煤矸石为原料时,经过煅烧活化后其保水性能最好的胶凝剂为水泥,保水性能、吸水性能和抗流失性能效果最好,其保水率为79.00%,吸水率为78.61%,流失率仅为0.50%。
The product was prepared by using coal refuse as raw material and adding the corresponding foaming agent and gelatinant,and its performance was further tested.In the process of the preparation of the porous soil,the single factor experimental method was used to first explore the effect of activation effect at different temperatures,and then the effect of the type of foaming agent and gelatinant on the performance of porous soil was investigated to develop the best type of water-absorbing material ingredients.The experimental results showed that when Shanxi coal refuse was used as raw material,the adhesive with the best water retention was cement after calcination and activation,and it also had the best water absorption and the resistance to loss performance with a water retention rate of 79.00%,a water absorption rate of 78.61% and a loss rate of 0.50%.
