Salinized soil modifier as well as preparation method and application thereof
The invention provides a saline soil modifier as well as a preparation method and application thereof, and relates to the technical field of saline soil modification. The saline soil modifier comprises the following raw materials: cement, lime, fly ash, an exciting agent, zeolite, calcium silicate, PVA (Polyvinyl Alcohol) and the like. Meanwhile, the mass ratio of the calcium silicate to the PVA is limited to be (1.5-2): 1, and the exciting agent is calcium chloride and water glass; the mass ratio of the calcium chloride to the water glass is (1-2): (1-2). By adjusting the raw material composition and proportion of the salinized soil modifier, the pavement performance of solidified soil can be improved on the premise of low mixing amount, the strength and water resistance of the solidified soil are improved, the stability is good, the engineering performance of the salinized soil can be remarkably improved, the service life of a roadbed is prolonged, and the salinized soil modifier has wide application prospects.
本发明提供了一种盐渍土改性剂及其制备方法与应用，涉及盐渍土改性技术领域。本发明的盐渍土改性剂包括水泥、石灰、粉煤灰、激发剂、沸石、硅酸钙、PVA等原料；同时本发明还限定了所述硅酸钙和所述PVA的质量比为(1.5～2):1，所述激发剂为氯化钙和水玻璃；所述氯化钙和水玻璃的质量比为(1～2):(1～2)。本发明通过调整盐渍土改性剂的原料组成及其配比，能够在较低掺量的前提下改善固化土的路用性能，提高固化土的强度及其阻水性能，且稳定性良好，能够显著提高盐渍土的工程性能，延长路基的使用寿命，具有广泛的应用前景。
