ABSTRACT:
A water soluble chemical composition for use as a soil stabilizer, conditer and structuring agent includes a dispersing agent such as a polyanionic sulfonated urea-melamine formaldehyde condensate, an aggregating agent such as a non-ionic water soluble urea-formaldehyde condensate having relative weight average molecular weights between 400 to 10,000 and polydispersity between 2.5 to 10, and a basic salt like di-sodium tetra borate and/or a neutral salt like sodium chloride and a nitrogen potassium or phosphorous containing compound such as potassium nitrate, phosphoric acid, potassium dihydrogen orthophosphate and the like, wherein the ratio of urea-formaldehyde to sulfonated urea-melamine-formaldehyde is between 0.2:1 to 2.0:1 and the final solid contents of this composition is between 1-15%. These compositions are then sprayed on top of sand or soil with conventional equipment and will impart significant improvements in their mechanical properties and their erosion resistance to water and wind.
