| 摘 要： | 研究了氢氧化钠、水玻璃、氢氟酸和磷酸对黄河中游不同地区土壤的侵蚀激活效果,结果表明,磷酸对土有很好的激活作用,掺入磷酸的土做成试件抗压强度较不掺加磷酸的土有很大提高,并且随着磷酸掺量的增多,强度继续增长,耐水性也有很大改善。红外及微观分析表明,磷酸能够改变土粒表面的羟基团,并且磷酸与土中的碳酸盐等生成肉丝状的磷酸钙晶体,分布在土粒的周围,胶结土壤。

| Abstract: | The paper studies the erosion activation effect of sodium hydroxide,sodium silicate,hydrofluoric acid and phosphoric acid on the soil in different parts of the middle reaches of Yellow River.As the experiment shows,samples composed of soil added into phosphoric acid show higher compressive strength than it composed of pure soil.The more phosphoric acid in it,the higher compressive strength and better water-resistance it shows.The infrared and microcosmic analysis shows that phosphoric acid,which can change ... |
