Abstract
Methods for increasing soil stabilization utilizing an anionic surfactant and a solution. Varying amounts of the anionic surfactant sodium dodecyl sulfate ('SDS') is added to soils along with a solution of calcium chloride. A mixing procedure is then used to mix the SDS-soil matrix with the calcium chloride solution. The micelles surround the soil particles, creating a matrix, and then the calcium ions of the calcium chloride solution bonds the micelle complex together. The resulting calcium dodecyl sulfate ('CDS') complex is very hard, relatively insoluble, and very strong. This process can be reversed by exposing the CDS complex to seawater. The sodium ions of the seawater exchange with the calcium ions of the CDS complex reforming the SDS surfactant.
